How to Do Oblique Crunches

  1. Lie on your back, with your hands on the side of your head and your knees bent to about 90 degrees.
  2. Contract your abs and lift your upper body diagonally, so that the elbow and shoulder on one side of your body move towards the knee on your other side.
  3. Bend as far as possible and then return to the starting position.

Commentary

The oblique crunch is a classic bodyweight exercise for strengthening your internal and external obliques. 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.
