Movement media
Accessible movement summary
Stand with the bar at the thighs, feet about hip width, knees softly bent, and lats engaged. Push the hips back while keeping the bar close to the legs and the spine long. Lower until a strong hamstring stretch is reached without the pelvis tucking or the back rounding. Drive the hips forward to stand tall, finishing with glutes rather than leaning backward.
Key cue: Close the car door with your hips.
