Step by step

  1. Stand with your back against the pad and your shoulders under the pads.
  2. Place your feet in the middle of the platform, shoulder width apart.
  3. Release the safeties and lower by bending your knees until your thighs are parallel to the platform or a bit lower.
  4. Push back up through your whole foot.

Tip: Feet lower on the platform work your quads more.
