Stand with your feet shoulder-width apart, weight in your heels, and your arms at your sides.
Push your hips back, bend your knees, and lower your body into a squat. Place your hands on the floor, shifting your weight onto your hands. Jump your feet back to softly land on the balls of your feet in a plank position. Your body should form a straight line from your head to heels. Be careful not to let your back sag or your butt stick up in the air, as both can keep you from effectively working your core. Lower your body all the way down to the floor. Jump your feet back so that they land just outside of your hands. Reach your arms over head and explosively jump up into the air. That’s one rep.
