@painacademy: You might look absolutely ridiculous doing this-but it's one of the most underrated ab exercises you've never heard of. Start in a sprinter's stance with your right leg forward and left arm bent at 90 degrees. Now swing your arms as fast as you can. Why does it work so well? Your core has to stabilize to keep you upright. Try it and you'll be shocked at how challenging-and effective-it is.
