Tabata training is one of the most popular forms of high-intensity interval training (HIIT). It consists of eight rounds of high-intensity exercises in a specific 20-seconds-on, 10-seconds-off interval. It may only take four minutes to complete a Tabata circuit, but those four minutes may well push your body to its absolute limit.
8 Rounds of each exercise (20 sec Work, 10 sec Rest)
