How to do it

  1. Lie on your back with your knees bent and feet flat, holding a weight plate against your chest with both hands.
  2. Anchor the feet under something or have a partner hold them.
  3. Curl the trunk up into a sit-up, and as you rise, press the plate straight up towards the ceiling.
  4. Finish sitting tall with the arms locked and the plate directly overhead.
  5. Lower the plate back to the chest as you uncurl the trunk to the floor.
  6. Repeat, timing the press so it finishes as the sit-up finishes.
