How to Do
How to Do Medicine Ball Crunches
The medicine ball crunches should begin with good posture to avoid injury. Brace the spine by drawing your lower abdomen inward. Your core muscles should be activated to support your posture as you perform the exercise.
If any pain is experienced, immediately stop the medicine ball crunches.

2. Extend your arms in a straight line above your head.
3. As you sit up, keep them straight, and as you come down, reach back so the medicine ball contacts the ground behind your head. Rep for three sets of 15 to 20 reps, or whatever circuit training interval you've specified.
