High Intensity Interval Training (HIIT) is a kind of exercise that consists of short, intense bursts of action followed by brief intervals of recuperation. This pattern of exercise may be repeated several times. Because of this, they started looking for methods that were efficient, didn't cost a lot of money, and could burn a lot of calories in a short period of time to establish a home-based weight reduction programme that is successful via the use of HIIT. The primary purpose of this research is to investigate the effects of HIIT on a participant's physical fitness components. 60 schools were chosen, and individuals were selected for this study and being randomly allocated to either the experimental group (n = 30) or the control group (n = 30). The High Intensity Interval Training (HIIT) programme was implemented 30 seconds of each exercise followed by 10 seconds of recovery. This routine was repeated by all of the individuals for a total of 12 weeks. The number of exercise repetition was also increased in staircase method. The pre-and post-treatment mean values showed a significant result in experimental the groups (<0.05) and control group did not show any improvement. This study provides the evidence that HIIT is proved effective in improvement of health-related physical fitness components among school going children

High-intensity interval training (HIIT) consists of alternating periods of intensive aerobic exercise with periods of passive or active moderate/mild intensity recovery. The purpose of the present study is to motivate other researchers to conduct a study on High-intensity interval training (HIIT) and spread knowledge about this training. this article was compiled through previous studies which are available on the internet, in theses, and in books. Search through Electronic databases to identify all related articles on HIIT and its impact or effect on the human body. Through this research or investigation, we have found that HIIT has lots of benefits like burning calories, improving muscle mass, improving endurance, maintaining a healthy heart, helping in maintaining diabetes, improving aerobic capacity and anaerobic capacity, and improving explosive strength. From this study, it was concluded that High-intensity interval training (HIIT) is very beneficial to maintaining good health, and it’s recommended to perform any kind of High-intensity interval training (HIIT) at least twice a week.
