How to Do Crunches

  1. Lie on your back, with your hands in front of your chest and your knees bent to about 90 degrees.
  2. Lift your upper body by contracting your abs and bending forward.
  3. Bend as far forward as possible while still keeping your low back in contact with the floor, and then return to the starting position.

Commentary

The crunch is a classic body weight exercise for strengthening your abs. The exercise can be varied by lying on a soft training ball (i.e. pilates/bosu ball), and you can increase the load by holding a weight against your chest.
