There is nothing nice about Tabata This. It's an intense cardio workout and you just try to hold on and make it to the end! The workout consists of 5 exercises. You perform 8 rounds of each exercise: 20 seconds of work, 10 seconds of rest. There is NO rest between each exercise and the lowest number of reps on any given round is your score for that exercise.. keep that in mind and try to beat your score the next time!
