Instructions
Using bumper plates, place the barbell on the floor. With knees slightly bent, grip the bar slightly wider than shoulder width, with an overhand grip. Lift one leg so it is off the floor. Keeping your core tight, raise your torso to an upright position. Straighten knee of supporting leg as torso becomes upright. Lower the bar to the floor while raising lifted leg back behind. Keep back straight and knee of supporting leg slightly bent. Keep hip and knee of lifted leg extended throughout the movement. Once barbell contacts the floor, repeat.
Tips
Throughout the lift, keep arms and back straight. Full range of motion will vary from person to person. Those with less flexibility may need to bend knee of supporting leg more so barbell can contact floor. Or use blocks to lower the barbell on to.
