Stand with feet hip-width apart and a barbell over your mid-foot. Grip the bar with hands just outside shoulder width and keep a slight bend in your knees. Brace your core and hinge at the hips, pushing them back while lowering the bar down your legs with a flat back. Lower until you feel a hamstring stretch, then engage your hamstrings and glutes to return to standing, keeping the bar close to your body. Repeat for reps.
