How to do it

  1. Adjust the seat, secure your feet and grab the handles or set your chest against the pad.
  2. Exhale and round your torso forward, pulling your ribs down toward your hips.
  3. Squeeze your abs at the bottom, then return slowly without letting the weights touch down.
  4. Drive the movement by rounding your spine, not by pulling with your arms or bending at the hips.

Warm up first and pick a weight you can control through the whole movement. Stop if something hurts.
