The Tabata workout protocol is: for 20 seconds do as many reps of the assigned exercise as you can - then rest 10 seconds. Repeat this for a total of 8 intervals, 4 minutes total exercise. Score the lowest number of reps attained in any of the given 8 intervals.
Try to match your squats numbers on each of the Tabata Squat sets in this workout.
