This is the ultimate workout method to train your entire body in four-minute increments. "Tabata's short duration can increase a person's willingness to complete it," says trainer Selena Watkins. "It also increases the chances you'll do the routine regularly."

Shorter durations mean less stress on the body, and no excuse to skip a workout.


Do each exercise for four minutes (20 seconds on, 10 seconds off, for eight sets total), then move on to the next exercise. Choose either Workout 1 or Workout 2 for a single day, and incorporate both into your regular fitness routine.
