Standing with your feet a 6-8 inches apart, hold a barbell across the back as you would if you were doing a low- bar Squat. Let your lower back gently round forward as you lean forward at the waist until your torso is just below parallel to the floor. Keep your head in a neutral position. Hold for a moment, then come back up to the starting position. Good Mornings are an excellent exercise to work the lower back, glutes and hamstrings.
