How to do it

  1. 1Set your shoulders and back against the pads and place your feet shoulder-width on the platform.
  2. 2Release the safety handles and brace your core with your whole back against the pad.
  3. 3Bend your knees to lower yourself under control until your thighs are at least parallel.
  4. 4Keep your heels down and your knees tracking over your toes.
  5. 5Drive through your feet to press back up without locking your knees harshly, then repeat.

Tips & tricks

  • A higher foot placement targets the glutes and hamstrings more; a lower one hits the quads.
  • Keep your lower back flat against the pad throughout.
  • Control the descent rather than dropping into the bottom.

Common mistakes

  • Letting your knees cave inward under load.
  • Lifting your heels off the platform.
  • Rounding your lower back away from the pad at the bottom.
