INTRODUCTION
The trap bar was first introduced
in the strength and conditioning
literature by Gentry et al. (12) in
1987. This initial model was diamond
shaped with 4 sides in the lifting frame.
The frame has been adapted over the
years, and the most common design is
now known as hexagonal (i.e., 6 sides)
(Figure 1). The design of the hexagonal
bar (hereafter referred to as the hex
bar) was designed to increase the safety
of lifting exercises, specifically the
deadlift, by allowing the load to be kept
closer to the body by creating a barbell
frame that the athlete could lift within
(7,12,35). As seen in Figure 1, hex bars
can feature low and high handles, and
the dimensions of the bar are relatively
consistent across different manufac-
turers. For example, the distance within
the frame between the centers of the
handles is approximately 0.64 m,
whereas the distance between the
low and high handles is approximately
0.10 m. However, despite increasing
availability in training facilities, there
is still relatively little information
regarding the use of the hex bar.
This article will provide 3 exercise ex-
amples where the hex bar could be
used in the resistance training pro-
grams of athletes. These exercises will
be the deadlift, farmer’s walk, and jump
squat. In each instance, supporting
research literature will be provided as
to why the hex bar is applicable as
a training device. In addition to this,
information regarding the execution
of each exercise will be provided, as
well as load and volume recommenda-
tions. This information may have value
for the strength and conditioning pro-
fessional because it will demonstrate
how certain exercises can be adapted
depending on the characteristics of the
individual, and the availability of equip-
ment within the training facility.
THE DEADLIFT
The conventional deadlift performed
with a standard bar is a popular
strength exercise that targets the legs,
hip, back, and torso muscles
(11,16,20,32,34,35,37). However, this
exercise can be difficult to perform for
some individuals because of certain
physical limitations; anthropometrical
factors such as height, torso, leg, and
arm length can all influence an individ-
ual’s ability to successfully perform the
conventional deadlift (16). The impact
of these limitations formed part of the
justification for the original trap bar
design. When discussing the theoretical
advantages of this bar, Gentry et al. (12)
suggested that the trap bar: allowed the
load to be kept closer to the individual’s
center of mass; potentially reduced
stress on the lower back by keeping
the individual in a more upright

position; and positioned the forearms in
a more natural position, potentially
reducing stress on the wrist, elbow,
and biceps. As stated, the 6-sided bar
frame has become more commonly
used for performing the deadlift exer-
cise, and thus, several researchers have
investigated the potential benefits of
using the hex bar for this exercise
(7,20,25,35). The results from these
studies have provided some support to
the initial assertions of Gentry et al. (12).
Swinton et al. (35) compared the hex
bardeadliftperformedwiththelow
handles to the conventional deadlift
across loads ranging from 10 to 80%
of the 1 repetition maximum (1RM)
among elite male powerlifters. A greater
1RM load was lifted in the hex bar
deadlift (265.0 641.8 kg) versus the
conventional deadlift (244.5 639.5
kg), which could be related to a more
advantageous lifting position and
reduced bar displacement. When com-
pared with the conventional deadlift,
the hex bar led to lower moment arms
at the lumbar spine, hip, knee, and
ankle, which Swinton et al. (35) related
to the lifting position provided by the
hex bar design. Swinton et al. (35) found
that for loads above 60% of the 1RM,
bar displacement was reduced by
approximately 22% in the hex bar dead-
lift. Furthermore, the hex bar deadlift
reduced peak moments at the lumbar
spine and hip across a range of loads
and increased peak moment at the knee.
Swinton et al. (35) detailed that when
lifting with the hex bar, the position of
the bar created a flexion moment at the
knee, as the load was positioned behind
the knee for the majority of the lift. This
placed an increased demand on the
knee extensors to move the bar, while
reducing the lifting demands on the low
back muscles. Last, peak velocity and
power were greater in the hex bar dead-
lift for the 30–80% of the 1RM loads,
which could also be related to a more
advantageous lifting position provided
by the hex bar deadlift. Taken together,
Swinton et al. (35) recommended the
hex bar deadlift above the conventional
deadlift for individuals who may expe-
rience low back issues and also noted
the potential stimulus provided by the
greater power generated in this lift.
The results from Swinton et al. (35)
were also supported by Camara et al.
(7). In an analysis of strength-trained
men, Camara et al. (7) documented
that that when compared with the con-
ventional deadlift being lifted with
loads of 65 and 85% of the 1RM, the
hex bar deadlift performed with the
low handles resulted in greater activity
of the vastus lateralis in both the con-
centric and eccentric phases of the lift.
This relates to the findings from Swin-
ton et al. (35), who illustrated that the
moment arm created at the knee
placed greater demands on the knee
extensors. In further support of Swin-
ton et al. (35), Camara et al. (7) found
that peak force, power, and velocity as
measured by a force plate were all
greater in the hex bar deadlift.
Although many hex bar designs fea-
ture low and high handles (Figure 1),
there is very little research that has
investigated how using high handles
may affect the resulting movement pat-
tern of the deadlift. Most studies inves-
tigating the hex bar deadlift have used
the low handles (7,25,35), and only 1
study has exclusively investigated the
hex bar deadlift performed with the
high handles (20). Lockie et al. (20)
compared the 1RM high-handle hex
bar deadlift with the conventional
deadlift in strength-trained men and
women. Similar to Swinton et al. (35),
Lockie et al. (20) found that a greater
load was lifted using the hex bar
(154.50 645.29 kg) when compared
with the deadlift with the bar (134.72
640.63 kg). As measured by a linear
position transducer, lift distance and
duration were reduced by approxi-
mately 22 and 25% in the high-
handle hex bar deadlift, respectively.
The 1RM high-handle hex bar deadlift
was also found to have greater peak
power, peak velocity, and peak and
mean force when compared with the
1RM conventional deadlift. This sup-
ports the data for the low-handle hex
bar deadlift provided by Swinton et al.
(35) and Camara et al. (7).
Collectively, the results from these
studies demonstrate several potential
benefits to using the hex bar with
either the low or high handles. This
includes a more advantageous lift posi-
tion, greater work completed by the
knee extensors, less stress on the lower
back, and high peak power, peak
velocity, and peak and mean force gen-
eration. Strength and conditioning
professionals who decide to use the
hex bar deadlift in programs for their
athletes or clients should use the typi-
cal guidelines for resistance training.
The examples shown in the Table fol-
low the general load, volume, and
intensity guidelines provided by the
National Strength and Conditioning
Association (1). It is suggested that
the hex bar deadlift could be used in
programs that focus on either hyper-
trophy or strength. Furthermore, given
there is application for the hex bar
deadlift in the training of athletes,
and strength and conditioning

professionals should also know how to
correctly execute this exercise.
EXECUTION OF THE HEXAGONAL
BAR DEADLIFT
Numerous authors have described the
technique and execution of the deadlift
(4,5,14–16,32). However, the execution
of the hex bar deadlift will be described
here and adapted from the deadlift
description provided by Graham (15).
Figure 2A shows the start position for
the low-handle hex bar deadlift,
whereas Figure 2B displays the start
position for the high-handle deadlift.
The standing position for the low-
and high-handle deadlifts is shown in
Figures 3A and 3B, respectively.
STARTING POSITION
The hex bar should be positioned on
the floor, with an equal load on each
side. The individual should step
inside the frame of the hex bar and
position themselves such that they
are in line with the handles and
weight plates.
The feet should be approximately
shoulder-width apart, with the toes
pointing forward or slightly outward
due to external rotation at the hips.
The individual should squat down by
flexing at the hips, knees, and ankles
to grasp either the low (Figure 2A)
or high (Figure 2B) handles with
a closed, neutral grip.
The shoulders should be in line with
the handles, and the head and chest
should be positioned in a manner
that allows for natural curvature of
the spine. The hips should be lower
than the shoulders because of flexion
at the hips and knees. As noted by
Graham (15) for the conventional
deadlift, the trapezius and upper
back should be relaxed and in a slight
state of stretch.
The feet should be flat on the floor,
with body weight evenly balanced
between these 2 points of contact.
This is the starting position for the
hex bar deadlift.
ASCENT—CONCENTRIC PHASE
The lift is initiated by driving down
into the floor (force production
should be evenly distributed
between each leg such that the resul-
tant body weight is centered
between the feet) and extending at
the hips and knees. The extension in
these joints should occur simulta-
neously, and the torso angle with
the floor should remain constant.
To achieve this, the head and chest
should be kept up, and the back

muscles should be contracted to
retract the shoulder blades.
The hips should not rise faster than
the shoulders, and the back must
remain slightly arched or flat
throughout the ascent. The arms
should also be extended at the el-
bows and held by the sides of the
body throughout the duration of
bar ascent. The load (i.e., the weight
plates) should remain in line with
the body.
During the conventional deadlift,
Graham (15) recommends that the
breath should be held until the bar
reaches the knees before exhaling
and then breathing normally. The
same breathing approach could be
taken for the hex bar deadlift.
The individual should continue to
simultaneously extend at the hips
and knees until a standing position
is achieved (Figure 3). Ideally, the
lifter should look forward to ensure
the head is positioned to encourage
a natural spine alignment in the
standing position.
DESCENT—ECCENTRIC PHASE
The descent is initiated by simulta-
neous flexion of the hips and knees.
The back should remain rigid and
flat or slightly arched. The head
and chest positions should allow
the maintenance of the torso posi-
tion and normal spine curvature.
The arms should remain extended
at the elbows and held by the sides
of the body throughout the descent.
The bar should be lowered with
control, and the load should remain
in line with the body. The individual
should inhale during the
descent (15).
Flexion of the hips and knees con-
tinues until the weight plates contact
the floor. This position should be the
same as that for the starting position
in the low- or high-handle hex bar
deadlift (Figure 2). Depending on the
goal of the set and repetition, the
weight plates should slightly touch
the floor before the next repetition
is initiated (“a touch-and-go” proce-
dure) (42), or the bar can come to
a complete stop on the floor, so no
momentum is present for the next
repetition.
FARMER’S WALK
The farmer’s walk is a strongman event
that involves an individual picking up
a heavy load (in a motion similar to the
hex bar deadlift) in each hand and then
walking a certain distance (usually
between 20 and 50 m) as quickly as
possible (18,45,47). This event has also
been recommended for the strength
training of athletes because it could
allow for the transfer of strength into
more “functional” actions (9,26,41,49).
Indeed, the farmer’s walk results in
high force production both during
the lift, and also when walking with
the load (45). This could have transfer
into maximal running. For example,
fast sprinting speeds require high force
production in both the vertical and
horizontal planes (23,28,29,43), and
this capacity may be developed
through the regular use of the farmer’s
walk. In addition to this, a faster farm-
er’s walk features a greater step length,
faster step frequency, and lower ground
contact times (18), which is also typical
of faster sprint performances
(6,21,22,24,30). The farmer’s walk
could potentially aid in developing
the strength and force capacities that
could be transferred into a sport-
specific action such as running and
sprinting.
As the load must be held throughout
the lift and walk, grip strength is
another physical component that
could be improved through the use
of the farmer’s walk (27,48,49). Zemke
and Wright (49) related the use of
strongman exercises such as the farm-
er’s walk to develop the grip required in
sports such as wrestling. Demands are
also placed on the linkages within the
body between those muscles that drive
the movement (i.e., the upper- and

lower-body muscles required to lift,
carry, and walk with the weight) and
those that need to stabilize the trunk
and core (27). This is notable because
the farmer’s walk with 70% of the 1RM
deadlift load caused greater trunk flex-
ion when compared with normal walk-
ing in male strongman athletes (45).
McGill (26) recommended using an
exercise such as the farmer’s walk to
strengthen the core musculature to
optimize the training of other sections
(i.e., the prime movers) of the body and
facilitate best athletic performance.
Therefore, in addition to being a spe-
cific training exercise for strongman
athletes, there may be benefits for other
athletes who use the farmer’s walk reg-
ularly in their training programs.
The load for the farmer’s walk is typi-
cally provided by specifically designed
bars (45,48). However, the farmer’s
walk is another exercise for which
the hex bar could be used. Lockie
et al. (20) noted similarities between
the high-handle hex bar deadlift with
the farmer’s walk. This is because the
farmer’s walk bars feature high handles
such as those on the hex bar. In addi-
tion to this, the hex bar frame should
allow enough space for an individual to
adopt an appropriate gait pattern to
walk with the load. Understanding
how the farmer’s walk could be per-
formed with the hex bar is especially
applicable for individuals who may not
have access to specific strongman
equipment, or those strength and con-
ditioning professionals who do not
have the finances to purchase extra
bars that may only be used for 1 exer-
cise. This will be described in the next
section. Furthermore, some training
recommendations for the farmer’s walk
with the hex bar have been provided in
the literature (13,41,45,46,48,49) and
are adapted here in the Table. Win-
wood et al. (47) noted that the most
common walking distance used by
strongman athletes was 20 m, although
distances up to 50 m have also been
featured when training with the farmer’s
walk. The load used for the hex bar
farmer’s walk will be dependent on the
strength and experience levels of the
individual. For those individuals less
experienced with performing the hex
bar farmer’s walk, a lighter resistance
should be prescribed (13). Shorter
recovery periods between sets can
also be set if the farmer’s walk is being
used as a conditioning activity (48,49).
Strongman athletes tend to rest for
longer periods (;4minutes)toin-
crease their ability to exhibit maximal
strength and power (47).
EXECUTION OF THE FARMER’S
WALK WITH THE HEXAGONAL BAR
There have been some brief descrip-
tions provided for the execution of
the farmer’s walk (18,45,47,48). How-
ever, none has incorporated the hex
bar, and therefore that information will
be provided here. The lift-off position
and start position use the same move-
ment pattern as the high-handle hex
bar deadlift, which is shown in Figures
2B and 3B, respectively. The walking
gait pattern for the hex bar farmer’s
walk is shown in Figure 4.
LIFT-OFF AND START POSITION
Set the distance the individual is
required to walk.
The bar should be positioned on the
ground with equal load on both
sides. The individual should pick
up the bar with the high handles in
the same manner as the first phase of
the hex bar deadlift (Figure 2B). The
standing position following bar
ascent is the starting position for
the hex bar farmer’s walk
(Figure 3B).
WALKING WITH THE HEXAGONAL
BAR
While keeping the arms extended at
the elbows and kept by the sides of
the body, the individual should start
to walk with the load (Figure 4). The
arms should remain extended at
the elbows and held at the sides of
the body throughout the walk, and
care should be taken to not swing
the load. A closed grip should be
maintained on the handle to control
the load. The trunk should remain
relatively upright (45), and the head
and chest should be up.
The individual should attempt to
cover the required distance as
quickly as possible. A correct balance
between step length and frequency
specific to the individual should be
adopted, within the context of the
spacing in the hex bar frame. The
individual should not attempt to
overstride to walk quickly, as this
will incur greater braking forces with
each ground impact (8). In addition,
walking with too high a step fre-
quency will shorten step length
because of the negative relationship
between these 2 variables (17).
Once the required walking distance
has been covered, the load should be
returned to the floor in the same
manner as the descent phase in the
hex bar deadlift.
JUMP SQUATS
In addition to strength, athletes need
to be able to express this strength
quickly in sport-specific situations.
This highlights the importance of
power for many athletes. Numerous
studies have shown relationships
between greater lower-body power
and enhanced athletic performance,
which has been documented by supe-
rior jumping or sprinting speed
(2,10,22,31,40). As a result, strength
and conditioning professionals will
use exercises that can encourage a high
movement velocity during training
(19). An example of a popular exercise
used to achieve this is the loaded jump
squat. The loaded jump squat is typi-
cally performed with a barbell held
across the shoulders, while the individ-
ual performs a countermovement jump
(36). However, there are limitations to
the use of a barbell. The individual
must actively hold down the bar across
the shoulders, cervical spine, and tra-
pezius such that it does not move dur-
ing the jump and landing. In addition,
the positioning of the load across the
shoulders during the jump squat can
increase the moment arm of the trunk,
which could cause the individual to
deviate from their unloaded counter-
movement jump technique (36). This

has led to research investigating the use
of the hex bar in the jump squat
(36,39,40).
In the hex bar jump squat, the bar is
held at arm’s length while the individ-
ual performs the jump while positioned
within the frame. Swinton et al. (36)
argued that the benefit of using the
hex bar for jump squatting is that
the load can be positioned closer to
the body’s center of mass and moved
independently of the torso. As a result,
Swinton et al. (36) suggested that this
could result in the individual more
closely reproducing their unloaded
countermovement jump technique,
with the potential benefits provided by
the external resistance. In addition to
this, a high external resistance may not
be required for the hex bar jump squat
to attain peak power, which is a training
focus when using loaded jump squats
(38–40,44). Turner et al. (39) found that
peak power in a hex bar jump squat
was generated when using a load of
10–20% of a 1RM box squat in profes-
sional male rugby union players. Fur-
thermore, Turner et al. (40) found that
peak power generated in the hex bar
jump squat significantly correlated
with countermovement jump (P,
0.01, correlation coefficient [r]5
0.80), 10-m sprint time (P,0.01, r
520.70), and 20-m (P,0.01, r5
20.75) sprint time in professional male
rugby union players. The positive rela-
tionship for the vertical jump indicated
that those rugby players who gener-
ated greater peak power in the hex
bar jump squat tended to have a higher
countermovement jump. The negative
relationships found by Turner et al.
(40) for the 10-m and 20-m sprints
indicated that rugby players with
a greater peak power in the hex bar
jump squat were faster over 10 and
20 m (i.e., they had lower sprint times).

Thus, the hex bar jump squat does
relate to sport-specific performance
and has application for the strength
and conditioning professional. If the
strength and conditioning professional
is using the hex bar jump squat to max-
imize power, it is recommended that
a load equaling approximately 10–
60% of the 1RM is used (39,40,44).
The wide range provided here relates
to the findings of Turner et al. (39), in
addition to the analysis of Baker et al.
(3) on jump squat peak power devel-
opment in rugby league players. Baker
et al. (3) found that stronger athletes
were able to generate peak power in
the jump squat with a greater percent-
age of their 1RM back squat. There-
fore, the actual load prescribed by the
strength and conditioning professional
will be dependent on the strength level
of the individual. Further training rec-
ommendations are shown in the Table.
A description of how the hex bar jump
squat should be executed is detailed
hereafter.
EXECUTION OF THE JUMP SQUAT
WITH A HEXAGONAL BAR
The jump squat has been described
previously, although this was with
either a barbell, Smith machine, or
dumbbells (33). The section will specif-
ically describe the technique used for
the hex bar jump squat. Figure 5 dis-
plays the start position, countermove-
ment, and flight phases for this
exercise.
STARTING POSITION
The bar should be positioned on the
ground with equal load on both
sides. The individual should pick
up the bar (with either the low or
high handles) in the same manner
as the first phase of the hex bar dead-
lift (Figure 2). The individual should
then stand upright with the bar, and
the arms should be fully extended
at the elbows and held at the sides
of the body (Figure 5A). The body
should be in line with the handles
and load. This is the starting
position.
COUNTERMOVEMENT AND FLIGHT
The arms should remain extended at
the elbows throughout the counter-
movement, with the load kept in line
with the body.
The individual should squat down
into an approximate half-squat posi-
tion, such that the knee angle between
the thigh and shank for each leg is
approximately 908(Figure 5B).
Immediately after reaching this posi-
tion, the jump is initiated by driving
down into the floor (the resultant
body weight should be centered
between the feet) and forcefully ex-
tending at the hips, knees, and ankles.
When airborne, the legs should
remain extended (Figure 5C). The
trunk should also extend, such that
the individual has a straight body
position while airborne.
LANDING
The individual should land with
both feet contacting the ground
simultaneously. Flexion should
occur at the hips, knees, and ankles
to cushion the landing in a manner
similar to that for the countermove-
ment (Figure 5B).
The arms should remain extended at
the elbows, and the trunk should flex
to control the load. The body should
remain in line with the weight
throughout the landing.
After the landing has been absorbed,
the individual should extend the
knees and hips to return to a standing
position (Figure 5A).
CONCLUSION
This article detailed the potential
advantages for using the hex bar dur-
ing exercises, such as the deadlift,
farmer’s walk, and jump squat. This
does not discount the value of using
the bar (or even dumbbells) for the
deadlift and jump squats, or the specific
farmer’s walk bars. Rather, this article
highlights how the hex bar could be
applied for these exercises as a form
of variation. Depending on the
strengths or physical limitations of
the individual, or the availability of
equipment, the strength and condition-
ing professional could use the hex bar
as a different form of resistance in the
deadlift, farmer’s walk, and jump squat.

... For example, the conventional deadlift (i.e., straight bar) can be difficult for some individuals to perform, especially those who suffer from lower back pain (Martín-Fuentes et al., 2020;Swinton et al., 2011). In this regard, substantial internal forces, moment arms, and electromyography amplitude were demonstrated in the lumbar spine muscle during the conventional deadlift (Camara et al., 2016;Lockie & Lazar, 2017;Swinton et al., 2011), potentially increasing the likelihood of lower back muscle pain or injury when lifting heavy loads (Lockie & Lazar, 2017). Hence, alternative variations of the conventional deadlift have been proposed to broaden its utilization at resistance training. ...

... The hexagonal bar deadlift (HBD) is a common variation of the deadlift exercise used by strength and conditioning coaches (Camara et al., 2016). The hexagonal bar was designed to improve lifting safety by allowing the practitioners to perform the lifting when the load is positioned closer to their body (Lockie & Lazar, 2017). This shift in load position can result in different neuromuscular stimuli, resistive torque at the trunk and hip, and kinematics output than the conventional deadlift (Camara et al., 2016;Lockie & Lazar, 2017;Swinton et al., 2011). ...

In this study, we examined the load-velocity relationship in the hexagonal bar deadlift exercise in women. Twenty-seven resistance-trained women were recruited. Participants performed a progressive load test up to the one-repetition maximum (1RM) load for determining the individual load-velocity relationship in the hexagonal bar deadlift exercise. Bar velocity was measured in every repetition through a linear encoder. A very strong and negative relationship was found between the %1RM and bar velocity for the linear (R 2 = .94; standard error of the estimation = 5.43% 1RM) and second-order polynomial (R 2 = .95) regression models. The individual load-velocity relationship provided even better adjustments (R 2 = .98; coefficient of variation = 1.77%) than the general equation. High agreement level and low bias were found between actual and predicted 1RM for the general load-velocity relationship (intraclass correlation coefficient = .97 and 95% confidence interval [0.90, 0.99]; bias = −2.59 kg). In conclusion, bar velocity can be used to predict 1RM with high accuracy during hexagonal bar deadlift exercise in resistance-trained women.
... From this position, they were required to flex their knees to ~90° (determined by an elastic band placed parallel to the ground by a tripod), then fully extended their lower limbs at the end of lifting. The HBD exercise started with the bar on the floor with the high-handle grip following the previous recommendations [21]. The shoulder should be in line with the handles and hips lower than the shoulders. ...
... From a mechanical perspective, shifting the load position can alter the kinematics and kinetics in lifting [18][19][20]. For example, the HBD makes it possible to keep the load closer to the individual's body, reducing the amount of torso inclination and horizontal displacement of the bar, which may provide favourable vertical displacement over the BSQ exercise [18,20,21]. From a practical perspective, the resulting equations provided here would enable strength and conditioning coaches to incorporate the VBT paradigm for the free-weight BSQ and HBD exercises in their RT programmes. ...

The aim of this study was to analyse the load-velocity and load-power relationships in the free-weight back-squat (BSQ) and hexagonal bar deadlift (HBD) exercises. Twenty-five (n = 25) resistance-trained men (age = 23.7 ± 2.8 years) performed a progressive load test at maximal intended velocity to determine their BSQ and HBD one-repetition maximum (1RM). Mean propulsive velocity (MPV) during the concentric phase of the lift was recorded through a linear encoder. Load-velocity and load-power relationships were analysed by fitting linear regression and the second-order polynomial, respectively, to the data. Maximum strength (1RM), MPV (30–80% 1RM), and power output (30–90% 1RM) were higher for HBD compared to BSQ exercise (p < 0.05). A very strong relationship between MPV and relative intensity was found for both BSQ (R2 = 0.963) and HBD (R2 = 0.967) exercises. The load that maximizes power output (Pmax) was 64.6 ± 2.9% (BSQ) and 59.6 ± 1.1% (HBD) 1RM. There was a range of loads at which power output was not different than Pmax (BSQ: 40–80% 1RM; HBD: 50–70% 1RM). In conclusion, the load-velocity and load-power relationships might assist strength and conditioning coaches to monitor and prescribe exercise intensity in the BSQ and HBD exercises using the velocity-based training approach.
... While not specific to the neck, a number of common gym-based exercises undertaken may elicit secondary strength adaptations in the neck, including the upper trapezius and the sternocleidomastoid muscles. 28 As an example, while a deadlift using a trap-bar is typically prescribed to target the lower body, the neck position (and therefore neck muscles) is important to maintain good lifting technique, and the trapezius muscles contribute to the stabilisation of the shoulder throughout the movement. 28 Thus, having a structured S&C program for elite women's football-code athletes may be sufficient to strengthen the neck musculature, however, the optimal neck strength of female athletes to reduce the risk of injury is still unknown. ...

Objectives The purpose of this study was to investigate the effectiveness of an isometric neck strengthening program to improve isometric neck strength in elite women's football-code athletes. Design Randomised controlled trial. Method Elite female soccer (n = 10) and Australian football (n = 30) players were randomised into either a control (n = 20) or experimental (n = 20) group for a 12-week intervention study during their respective seasons. While both groups undertook their prescribed strength and conditioning programs, the experimental group also performed isometric neck strengthening exercises three times per week prior to training. Isometric neck strength of the extensors, flexors, lateral flexors, and rotators were assessed pre, mid (Week 7), and post (Week 13) intervention with a hand-held dynamometer during early to mid-competition season. A mixed design analysis of variance was performed for statistical analysis. Results No significant group-by-time interactions in isometric neck strength were observed. All strength variables displayed a significant change over time throughout the 12-week period (p < 0.05). No significant between group differences in isometric neck strength variables were observed except for lateral left flexion (F(1, 38) =5.064, p = 0.030, η²p = 0.117). Conclusion The addition of isometric neck strengthening exercises did not improve neck strength beyond a standard strength and conditioning program for elite women's football-code athletes. While this specific program may not improve neck strength in elite women's football-code athletes, further investigation is needed to determine whether sport-specific neck strength exercises may improve neck strength or if lower-level competition athletes may still benefit from an isometric neck strengthening program.

Other phases of the lift (i.e., pause at the top of the lift, or the speed of bar lowering) were not standardized and subjects were allowed to use their preferred style, contributing to ecological validity of the study.

Jovanovic, M and Jukic, I. Within-unit reliability and between-units agreement of the commercially available linear position transducer and barbell-mounted inertial sensor to measure movement velocity. J Strength Cond Res XX(X): 000-000, 2020-The purpose of this study was to investigate the within-unit reliability of GymAware linear position transducer (GYM) and PUSH2 inertial sensor to measure mean velocity (MV) and peak velocity (PV) during hexagonal barbell deadlift (HBD) and to examine the agreement between GYM and PUSH2 devices. Twelve strength-trained men performed 2 HBD one-repetition maximum (1RM) sessions followed by 2 repetitions to failure assessments with 80 and 90% of daily 1RM. Barbell MV and PV were simultaneously monitored with 2 GYM and PUSH2 devices during all assessments. An ordinary least products regression was used to assess within-units agreement and whether PUSH2 can accurately predict GYM velocity. In addition, residual standard error (RSE) and smallest detectable change in load (SDC%1RM) were also calculated. GYM devices have been shown to be highly reproducible devices (RSE 5 0.019-0.021 m·s 21 ; SDC%1RM 5 1.795-2.679%). However, PUSH2 devices displayed a substantial amount of error (RSE 5 0.133-0.220 m·s 21) and lack of sensitivity (SCD%1RM 5 14.113-14.558%) to detect smallest change in load, which makes them untrustworthy for a regular use for monitoring athletes. Although very high correlations (r 5 0.915-0.948) have been observed between PUSH2 and GYM velocity recordings, PUSH2 overestimated both MV and PV as indicated by high fixed and proportional bias. The findings of the present study suggest that sport professionals should not use PUSH2 devices when the aim is to accurately monitor velocity variables during HBD exercise because low within-unit agreement and high fixed and proportional bias and RSE compared with GYM devices may compromise the utility of the collected data.
... Although the RDL is typically performed with a barbell, a less common method is with the use of the more recently popular hexbar. Hexbars were originally designed to decrease spinal load when completing the deadlift as the shape allows the lifter to keep the external load closer to the body (6,15,16). By keeping an external load closer to the individual's center of mass during a conventional deadlift, horizontal displacement of the weight can be reduced by up to 75% for low loads (i.e., ,60% 1-repetition maximum [1RM]) and approximately 22% for loads .60% ...
... The following technique is based off of the previous literature using a traditional barbell RDL (11,16). Starting position for the RDL will begin with the athlete stepping inside of the hexbar and position the midfoot in line with the middle of the bumper plates. ...

This column provides a description of the correct technique for a hexagonal bar Romanian deadlift (RDL). The use of the hexagonal bar provides a unique variation of the conventional RDL to promote a more advantageous upright body posture, thereby allowing greater loads to be lifted and reductions in spinal compression forces. Additionally, the use of the hexagonal bar RDL can aid in the development in the musculature of the posterior chain benefiting those who are required to sprint and jump regularly.
... Session one consisted of the completion of a survey regarding age, mass, height, resistance training history, estimated 1-repetition maximum (1RM), and injury history, as well as determination of hexbar deadlift 1RM. The hexbar deadlift was performed with technique previously outlined [15]. Loads for warmup sets and the initial testing set were determined based on the subject-reported estimated 1RM. ...

Knowledge of individual muscle force during strength and conditioning exercises provides deeper understanding of how specific training decisions relate to desired training outcomes. The purpose of this study was to estimate individual muscle forces during hexbar jumps with 0%, 20%, 40%, and 60% of the hexbar deadlift 1-repetition maximum utilizing in vivo motion capture and computational modeling techniques of male participants. Muscle forces for the gluteus maximus, biceps femoris, rectus femoris, vastus intermedius, gastrocnemius, and soleus were estimated via static optimization. Changes in muscle forces over the concentric phase were analyzed across loading conditions using statistical parametric mapping, impulse, and peak values. Conclusions about the effects of load differ between the three analysis methods; therefore, careful selection of analysis method is essential. Peaks may be inadequate in assessing differences in muscle force during dynamic movements. If SPM, assessing point-by-point differences, is combined with impulse, where time of force application is considered, both timepoint and overall loading can be analyzed. The response of individual muscle forces to increases in external load, as assessed by impulse and SPM, includes increased total muscle output, proportionally highest at 20%1RM, and increased absolute force for the vasti and plantarflexors during the concentric phase of hexbar jumps.
... Trap bars or hex bars have also been used to teach clean pull derivatives. The design of the trap bar puts athletes in a much more anatomical advantageous start position by reducing the stress on the lower back, allowing for a more upright set position, which may promote more optimal execution of triple extension in a loaded squat jump [24]. While unstable variations such as sandbags or waterbags, offer perturbative forces that require continuous body stabilization, especially at high velocities. ...

The power clean and its variations are prescribed by strength and conditioning coaches as part of the ‘big three’ to develop “total body strength”. This article explores the application of the power clean and its variations to athletic performance and introduces strength and conditioning coaches to teaching progressions, with specific emphasis on developing the correct body positioning required for the power clean. Teaching components are addressed with special reference to taller athletes. It is recommended that strength and conditioning coaches teach the hang clean follow a progression model to decrease movement complexity when advancing athletes to the power clean.

Background: Health and wellness programs can be implemented at police departments. Little research has detailed the characteristics of officers within these programs. Objective: To analyse the health and fitness data of officers involved in a health and wellness program from 2018-2020, and to profile the officers involved relative to population norms. Methods: Analysis was conducted on archival data from 633 officers (523 males, 110 females) who participated in a health and wellness program from a large city police department. Data included: body mass; body fat percentage; blood pressure (BP); estimated maximal aerobic capacity; sit-and-reach; push-ups; vertical jump; grip strength; sit-ups; bench press ratio. Data were grouped by year (2018, 2019, 2020), and a univariate ANCOVA with Bonferroni post hoc adjustment determined any significant between-group differences. Individual officer data were also compared to population norms. Results: The 2020 group had higher systolic BP compared to both other groups, and superior sit-and-reach and grip strength compared to the 2018 group (p < 0.05). Compared to population norms across the 3 years, 74-86% of officers had BP elevated above normal levels. Depending on the fitness component measured most officers (69-98%) were categorised as average or better. Conclusions: There were few differences between the year groups, although the 2020 officers did have superior sit-and-reach and grip strength. The higher systolic BP from the 2020 group may be indicative of the challenges of the year (pandemic, civil unrest). Officers generally had good profiles relative to population norms. The wellness program appeared to benefit the well-being of officers.

Punches in boxing are intricate actions requiring the coordinated and synergistic recruitment of leg, trunk and arm musculature. Maximal punches can have a marked impact on the outcomes of boxing contests. Currently, there is an absence of research appraising the biomechanics and physical performance-related qualities associated with boxing punches, and as such, there are no practical guidelines pertaining to resistance training and its impact upon these important characteristics. In this respect, coaches and boxers are reliant consequently upon non-scientific approaches to training and contest preparation. Thus, the purpose of this thesis was to quantify the biomechanics and physical performance-related qualities associated with maximal punching techniques common to amateur boxing, and investigate the extent to which resistance training enhances such features. Study 1 quantified the three-dimensional kinetics and kinematics of maximal punches common to boxing competition to identify the differences between punch types (straights, hooks, and uppercuts), whilst Study 2 investigated the movement variability of these measures across punch types. These studies revealed significant differences for the majority of kinetic and kinematic variables between punch types. High within-subject, between-subject, and biological variability were recorded for the same variables across punch types, independent of the amount of boxing experience. These findings confirm that kinetic and kinematic characteristics vary from punch to punch, with boxers appearing to manipulate kinematic variables in order to achieve a consistent intensity and end-product. Study 3 quantified the relationships between physical performance-related traits and kinetic and kinematic qualities of maximal punches, and revealed moderate-to-large associations with muscular strength and power. From this, Study 4 appraised the extent to which strength and contrast resistance training enhanced maximal punch biomechanics and physical performance-related qualities. The findings highlighted that contrast training was superior among male amateur boxers over a six-week intervention, though strength training alone also brought about improvements. This current research has advanced our understanding of maximal punching and the influence of resistance training on a variety of its determinants. Nonetheless, future research is required to identify if the same findings can be generalised to higher standards of boxing and whether alternative strength and conditioning strategies are equally, or more effective.

The high-handle hexagonal bar deadlift (HHBD), a variation of the conventional deadlift (CD), is said to reduce the lift range of motion, which may change the mechanics of the lift. However, no research has investigated this. This study compared the mechanics between a one-repetition maximum (1RM) CD and HHBD. Thirty-one strength-trained subjects (21 males, 10 females) completed a 1RM CD and HHBD. A linear position transducer measured lift distance, duration, and work; and peak and mean power, velocity, and force. The presence of a sticking region (SR) was determined for each lift. A repeated measures ANOVA calculated differences between 1RM CD and HHBD mechanics. A one-way ANOVA compared the mechanics of each lift between subjects who exhibited a SR or not, and the SR between the CD and HHBD. Significance was set at p < 0.01. Subjects lifted a greater load in the HHBD (154.50 ± 45.29 kg) compared to the CD (134.72 ± 40.63 kg). Lift distance and duration were 22% and 25% shorter during the 1RM HHBD, respectively. The HHBD featured greater peak power and velocity, and peak and mean force; more work was done in the CD. Most subjects did not exhibit a CD (68%) or HHBD (77%) SR. There were no differences in CD or HHBD mechanics between subjects with or without a SR, and no differences in SR region distance or duration between the CD and HHBD. Greater force can be generated in the HHBD, which could have implications for strength training adaptations over time.

This study sought to obtain some preliminary sagittal plane kinematic data on a common strongman event (and conditioning exercise) ‘the farmers walk’ and gain some insight into its kinematic determinants. Five experienced resistance trained males performed three, 20 m farmers walks at maximal speed while carrying 90.5 kg in each hand. Farmers walk average velocity was significantly greater in the middle (8.5–11.5 m) and latter (17–20 m) than initial stage (0–3 m), with this also associated with significant increases in stride length and stride rate and reductions in ground contact time. Comparisons between each subject’s fastest and slowest trials revealed virtually no significant differences. In contrast, the fastest three trials (irrespective of subject) had significantly greater stride length, stride rate and reduced ground contact time than the slowest three trials. Based on the impulse-momentum relationship, the production of high anterior-posterior and vertical impulses over short ground contact times may be crucial for farmers walk performance. Future studies should utilise larger samples and investigate the ground reaction and joint kinetics of the farmers walk and compare these values to other forms of bipedal gait and resistance training exercises to get a more complete understanding of the biomechanics of this exercise.

Those training for strength and power commonly use different bars and different lifts. The hexagonal barbell (HBar) and Olympic barbell (OBar) are frequently used training implements, and the mid-thigh pull and deadlift are two popular exercises. Therefore, the purpose of this study was to compare force between an HBar and OBar for a mid-thigh pull (MTP), deadlift (DL) and countermovement jump (CMJ). Twenty resistance trained men (age = 24.05 +/- 2.09 yrs, ht = 178.07 +/- 7.05 cm, mass = 91.42 +/- 14.44 kg) volunteered to participate and performed MTP and DL utilizing both bars, and a CMJ. Joint angles were recorded for all pulls and the bottom position of the CMJ. Peak ground reaction force (PGRF) was greater in the MTP (3186.88+/-543.53N) than DL (2501.15+/-404.04N) but not different between bars. MTP joint angles were more extended than DL, and the strongest correlations between isometric and dynamic performance were seen between DL PGRF and CMJ impulse (OBar r=0.85; HBar r=0.84). These findings are likely due to the different anatomical characteristics between the MTP and DL as well as the similarity in joint angles between the DL and CMJ. Therefore, the deadlift may be an optimal choice for athletes in jump dependent sports, regardless of bar. Copyright (C) 2016 by the National Strength & Conditioning Association.

The deadlift exercise is commonly performed to develop strength and power, and to train the lower body and erector spinae muscle groups. However, little is known about the acute training effects of a hexagonal barbell vs. a straight barbell when performing deadlifts. Therefore, the purpose of this study was to examine the hexagonal barbell in comparison to the straight barbell by analyzing electromyography (EMG) from the vastus lateralis, biceps femoris, and erector spinae, as well as peak force, peak power, and peak velocity using a force plate. Twenty men, with deadlifting experience volunteered to participate in the study. All participants completed a one-repetition maximum (1RM) test with each barbell on two separate occasions. Three repetitions at 65% and 85% 1RM were performed with each barbell on a third visit. The results revealed there was no significant difference for 1RM values between the straight and hexagonal barbells (mean ± SD in kg = 181.4 ± 27.3 vs. 181.1 ± 27.6, respectively) (p > 0.05). Significantly greater normalized EMG values were found from the vastus lateralis for both the concentric (1.199 ± 0.22) and eccentric (0.879 ± 0.31) phases of the hexagonal barbell compared to the straight barbell deadlift (0.968 ± 0.22 and 0.559 ± 1.26), while the straight barbell deadlift led to significantly greater EMG values from the bicep femoris during the concentric phase (0.835 ± 0.19) and the erector spinae (0.753 ± 0.28) during the eccentric phase compared to the corresponding values for the hexagonal barbell deadlift (0.723 ± 0.20 and 0.614 ± 0.21) (p ≤ 0.05). In addition, the hexagonal barbell deadlift demonstrated significantly greater peak force (2,553.20 ± 371.52 N), peak power (1,871.15 ± 451.61 W), and peak velocity (0.805 ± 0.165) compared to the straight barbell deadlift values (2,509.90 ± 364.95 N, 1,639.70 ± 361.94 W, and 0.725 ± 0.138 m/s) (p ≤ 0.05). These results suggest that the barbells led to different patterns of muscle activation, and that the hexagonal barbell maybe more effective at developing maximal force, power, and velocity.

The introduction of the shorter match formats for cricket (i.e. Twenty20) requires batsmen to be proficient in sprint acceleration to increase run scoring potential. Therefore, the study aim was to identify the kinematics of faster acceleration performance of non-striking batsmen when completing a quick single. Eighteen experienced male cricketers currently playing cricket in a regional competition in Australia completed 17.68-meter (m) sprints utilizing a match-specific start (walking start, bat dragged through crease, leg guards worn). Timing gates recorded the 0-5 and 0-17.68 m time. Joint and step kinematics were analyzed through the first and second steps via three-dimensional motion analysis. Subjects were split into faster and slower groups according to 0-5 m time, and a one-way analysis of variance determined significant (p < 0.05) between-group differences. Effect sizes and Pearson's correlations (r) were also calculated. The faster group was significantly quicker for the 0-5 and 0-17.68 m intervals, and had a 10% longer first, and 11% longer second, step. Second step swing leg hip adduction was 23% greater in the faster group. A significant, negative correlation (r = -0.647) was found between second step drive leg extension and 0-5 m time. Batsmen should cover the initial 5 m of a quick single in the shortest time possible to increase the likelihood of a successful run. This is aided by longer first and second steps, and increased hip adduction to transition into normal sprint technique. Step length development should be a key consideration for coaches attempting to improve quick single performance. Copyright (C) 2015 by the National Strength & Conditioning Association.

This study examined the influence of force plate targeting, via stride length adjustments, on the magnitude and consistency of ground reaction force and segment angle profiles of the stance phase of human running. Seven male subjects (height, 1.77 m ± 0.081; mass, 72.4 kg ± 7.52; age range, 23 to 32 years) were asked to run at a mean velocity of 3.2 m · s-1 under three conditions (normal, short, and long strides). Four trials were completed for each condition. For each trial, the ground reaction forces were measured and the orientations of the foot, shank, and thigh computed. There were no statistically significant differences (p > .05) between the coefficients of variation of ground reaction force and segment angle profiles under the three conditions, so these profiles were produced consistently. Peak active vertical ground reaction forces, their timings, and segment angles at foot off were not significantly different across conditions. In contrast, significant differences between conditions were found for peak vertical impact forces and their timings, and for the three lower limb segment angles at the start of force plate contact. These results have implications for human gait studies, which require subjects to target the force plate. Targeting may be acceptable depending on the variables to be analyzed.

Recent studies indicate that the utilization of the hexagonal barbell jump squat (HBJS) compared to the traditional barbell jump squat may offer a superior method of developing peak power. The notion that a single optimal load may be prescribed in training programmes aiming to develop peak power is subject to debate. The purpose of this study was to identify the optimal load corresponding with peak power output during the HBJS in professional rugby union players. Seventeen professional rugby union players participated in this study. Participants performed 3 unloaded countermovement jumps on a force-plate, as well as 3 HBJS at each of the following randomized loads: 10%, 20%, 30% and 40% of box-squat 1 repetition maximum (1RM). Peak power output was the dependent variable of interest. A one-way repeated measures ANOVA was conducted to compare peak power output across each load. A significant main effect for load was observed [Wilk's Lambda = 0.11, F (4, 13) = 18.07, p < 0.01, partial eta squared = 0.88]. Results of the Bonferroni adjusted pairwise comparisons indicated that peak power output in the HBJS is optimized at a load range between 10-20% of box squat 1RM. The results of this study indicate that the use of the HBJS with a training load between 10-20% of box squat 1RM optimizes peak power output in professional rugby union players.

Recent research suggests that jump squats with a loaded hexagonal barbell are superior for peak power production to comparable loads in a traditional barbell loaded jump squat. The aim of this study was to investigate the relationship between relative peak power output during performance of the hexagonal barbell jump squat (HBJS), countermovement jump (CMJ) height and linear acceleration speed in rugby union players. Seventeen professional rugby union players performed 10m and 20m sprints, followed by a set of 3 unloaded CMJ's and a set of 3 HBJS at a previously determined optimal load corresponding with peak power output. The relationship between HBJS relative peak power output, 10m and 20m sprint time, and CMJ height was investigated using correlation analysis. The contribution of HBJS relative peak power output and CMJ height to 10m and 20m sprint time was investigated using standard multiple regression. Strong, significant, inverse correlations were observed between HBJS relative peak power output and 10m sprint time (r = -0.70, p < 0.01), and 20m sprint time (r = -0.75, p < 0.01). A strong, significant, positive correlation was observed between HBJS relative peak power output and CMJ height (r = 0.80, p < 0.01). Together HBJS relative peak power output and CMJ height explained 46% of the variance in 10m sprint time, whilst explaining 59% of the variance in 20m sprint time. The findings of the current study demonstrate a significant relationship between relative peak power in the HBJS and athletic performance as quantified by CMJ height and 10m and 20m sprint time.
