Sit on a bench, feet flat, shoulder-width apart. Barbell across your upper back (not on your neck). Engage core, chest up. Inhale, hinge forward at hips, back straight. Lower torso nearly parallel to the floor. Exhale, return to start, squeeze glutes and hamstrings. Repeat.
Secure barbell on upper back. Maintain neutral spine. Hinge at hips, not waist. Control descent and ascent. Start light to master form. Keep feet firmly planted.
