How to do it
Stand with feet shoulder-width apart. Breath in, engage your core and keep your chest up as you drop into a squat. Continue lowering your butt until your thighs are parallel with the floor. Exhale and drive back up through heels to jump up, using your arms as necessary. Land with bent knees to absorb impact. That’s one rep. Do three sets of 12 to 20 reps.
