DESCRIPTIONStand up straight with abs tight, shoulders back, and hands on your hips.
Inhale as you take a large step back with your right foot, and lower your right knee down to the floor until it is about an inch from the ground while keeping your weight on you left heel. Do not allow your left knee to go past your toes. Exhale as you return to the starting position by pressing up through your left heel.
Switch sides, and alternate to complete reps. Hold dumbbells by your sides, or a barbell across the back of your shoulders to make more difficult.
