1. Get into the starting position by deadlifting a barbell off the floor, or by unracking it from a barbell rack.
2. Inhale, brace your core slightly, and lean forward by hinging in your hips. Keep your knees almost completely extended.
3. Lean forward as far as possible without rounding your back. You don’t have to touch the barbell to the floor, although it is OK if you do.
4. Reverse the movement and return to the starting position. Exhale on the way up.
