Muscles trained: hamstrings, glutes, lower back
Set a loaded barbell on the supports of a rack or cage set just below waist level. Grab the bar with an overhand grip that's just beyond shoulder-width and take a step back. Stand holding the bar at arm's length and resting on the front of your thighs. Your feet are shoulder-width apart and your knees slightly bent. Your eyes are focused straight ahead. Slowly bend at the hips as you lower the bar just below your knees. Don't change the angle of your knees. Keep your head and chest up and your lower back slightly arched. Pause there and then lift your torso back to the starting position, keeping the bar as close to your body as possible.
