Objective: This review synthesized evidence on the use of body weight exercises through high-intensity interval training (HIIT-BW). Methods: The research was performed in the Science Direct, Embase, MEDLINE, PEDro, SciELO, CINAHL, and LILACS databases from 2013 to 2023. Descriptors such as: high-intensity whole-body, high-intensity functional training, whole-body, whole-body training, whole-body calisthenics, high-intensity calisthenic training, and HIIT bodywork were used. In addition, original articles in English and Portuguese that addressed body weight HIIT were included. The final analysis consisted of 12 articles. Results: HIIT-BW protocols presented varied methodological characteristics: number of series ranged from 4 to 20; stimulus time ranged from 5 to 30 seconds with all-out intensity; and the passive interval ranged from 10 to 35 seconds between the series in 11 studies. The acute responses resulted in psychophysiological changes, increased lactate, Rated Perceived Exertion (RPE), heart rate (HR), fatigue, sweating rate, body size perception, training load, maximum oxygen volume (VO2max), caloric expenditure, perception of recovery, feeling of anger, mood disorder, intention of physical activity and reduction in the perception of pleasure, variability in HR, number of movements in complex exercises, and vigor. When compared with moderate continuous exercise and other high-intensity interval training protocols, HIIT-BW presented similar responses, however the use of preferred songs in the session provided an increase in the number of movements and perception of pleasure when compared with sessions that used non-preferred music and without music. Conclusion: In conclusion, based on data from studies found in the literature, HIIT-BW sessions promote increased feelings of fatigue, anger, mood disorder, RPE, HR, lactate, sweating rate, body size perception, caloric expenditure, and VO2. The results found helped to project indicators of long-term physical fitness and to plan sessions aimed at improving the lifestyle of its practitioners.
