Men’s Health magazine Medicine Ball Ab Workout Challenge from the December 2008 issue:
Modified version of the original Medicine Ball Ab Workout Challenge for people with bad backs (exclude sit ups and crunches):
These are some tough medicine ball exercises for your abs!!!
Personally, I love stability and medicine ball exercises as they are very effective for developing sexy abs, strengthening the core and training stabilizer muscles. I no longer do crunches and sit ups on the floor… don’t wanna cause more damage to my poor back.
