The kettlebell is a popular device for exer-cises designed to enhance athletic perfor-mance, and for injury rehabilitation. 1,2 The girya, Russian for "kettlebell," is a cast iron weight that resembles a cannonball with a handle. 3,4 Kettlebells range in weight from a few pounds to over 100 pounds. Weight selection is dependent upon the nature of the exercise, or the user's level of experi-ence and strength (Table 1). The kettlebell first appeared in the Russian dictionary in 1704. 3,4 Originally used as a counterweight for market produce scales, it became a popular training tool among Rus-sian strongmen and weightlifters, known as gireviks or kettlebell men, in the early 20th century. 3,5 The unique shape and off-set center of gravity permit the use of curvilinear movement patterns and the development of centrifugal force. 5,6,7,8 The kettlebell's shape places the weight in a hanging position, which keeps the force of the weight directed downwardly, helping to maintain a vertical body position throughout performance of the exercise. 9 University multistep, progression-based total body exer-cise that is performed by "getting up" from a supine position to a standing position. 8,9 The origins of the TGU can be traced over 200 years to Turkish wrestling training. 6,9 Before allowing a wrestler to proceed to the next stage of training, he was required to get up from the ground nimbly, while holding a kettlebell overhead and maintaining con-trol. 9 Today, the TGU is included in training programs because of its versatility, the chal-lenge it presents to maintenance of stability, and the demand that it imposes for develop-ment of strength throughout the entire body. The TGU can serve as a corrective exercise, a movement screen, or a conditioning workout. 9 Given the step-wise nature of the movement, it can also be used to elicit adap-tations in untrained and injured individuals or to challenge well-trained individuals who require a high-intensity stimulus (Table 2). © 2012 Human Kinetics -IJATT 17(4), pp. 8-13
