How to do it

Sit in the plate-loaded ab machine with your chest against the pad and grip the handles overhead. Crunch your torso down while driving your knees up toward your chest, then return under control without letting the weight pull you back fully.

  1. 1Your abs shortening as your ribs and knees draw together
  2. 2Constant tension across the front of your core throughout the rep
  3. 3A controlled return rather than letting the weight stretch you out

Common mistakes

  • Do not pull with your arms or hip flexors to move the weight
  • Avoid using momentum to swing your knees up
  • Do not let the stack yank you back into full extension
