1. Lie on the floor and roll the barbell up to your chest or have a partner hand it to you.
2. Grasp the bar at about shoulder width and arch your back so there’s space between your lower back and the floor.
3. Lower the bar to your sternum, tucking your elbows about 45 degrees to your sides. When your triceps touch the floor (not your elbows), press the bar back up.
