Give your abs a rest and work your lower body with the atomic get-up into a front kick. Start kneeling and keep your body tall with your shins flat on the ground. With power, jump up onto your feet and come into a squat, and then stand tall. Perform a kick with your left leg, and then return to the starting position. Repeat, and perform a kick with your right leg. Complete 10 to 20 reps.
