Fast Sit Ups

  1. Lie down on a comfortable surface on your back.
  2. Extend your legs and create a bend in your knees, let the soles of your feet rest flat on the ground.
  3. Assume your starting position with your head raised slightly off the ground and your arms extended forward just outside your knees.
  4. Sit up as fast as you can, so your hands extend past your knees and then return to the starting position as fast as you can – repeat until failure.
  • Rather than aiming for constant load on the muscles, complete as many reps as possible within 40 seconds.
  • Work quickly until you start to lose your proper form.
  • The goal is to work until fatigued.
