Muscles trained: Glutes, hamstrings, lower back

Set a loaded barbell on the supports of a rack or cage just below shoulder height. Step under the bar and rest the barbell comfortably on your upper back. Slowly bend forward at the hips as you lower your chest as far as you can go while maintaining the natural arch in your lower back or until your upper body is parallel to the floor. Keep your head up and maintain the same angle of your knees. Lift your upper body back to the starting position.
