This version of the crunch works both the upper and lower portion of the abs.
- Lie on your back and bring your knees up to a 60 degree angle, keep your feet flat on the floor.
- Place your hands on either side of your head (over your ears).
- Curl up raising your right elbow and your left knee so that they touch over your chest.
- Return to the starting position and repeat with alternate arms and legs.
Note: Contract your abs as you twist during this exercise.
