Start in a squat (feet under shoulders, toes facing forward, thighs parallel to floor) with torso upright and hands clasped in front of chest. Press through feet to straighten legs and jump up off the floor while swinging straight arms behind body. Land back in a squat position. That’s one rep. Perform 10 reps, then immediately continue on to your next move (you’re doing six to eight total). When you’ve completed all of your exercises, rest for 30 seconds to one minute. Then, repeat twice more for a total of three rounds.
