The Ab Crossover (aka the Ab Chopper) is a great way to work your abs while working your shoulders a little bit too. It's a good alternative to boring old crunches so try it out.
- Lie on your back with your knees bent and hands straight overhead, clasped together.
- Crunch up (contract your abs) while bringing your hands over to the outside of your left thigh. That's is one rep.
- Lower back to start position and repeat to the outside of your right thigh. That is another rep.
- Do two sets of 20 reps.
Fit's Tips: If this is too easy then hold a light medicine ball in your hands. You can also make it more difficult by doing more reps.
