How to do it

Lie on your back with your legs spread wide and the soles of your feet apart, knees relaxed open. Reach forward and sit up toward your feet by contracting your abs, then lower slowly back to the floor under control.

  1. 1Your abs contracting hard to pull your torso up
  2. 2A controlled lower with tension held in the core
  3. 3Your lower back rounding off the floor segment by segment

Common mistakes

  • Yanking your head or neck with your hands
  • Using momentum to throw yourself up
  • Dropping flat instead of lowering under control
