How to do it

  1. Lie on your back with arms at your sides and knees bent, feet just off the floor.
  2. Contract your abs to curl your hips off the floor, bringing your knees over your chest.
  3. Pause briefly at the top.
  4. Lower your hips slowly back to the start without letting the feet touch down.

Tips

  • Use the abs, not momentum, to lift the hips.
  • Keep the arms relaxed on the floor.
