Jackknifing Off

I started an insane new workout yesterday that involves all kinds of acrobatic maneuvers on a Swiss Ball. During the workout I kept wanting to giggle, because I really felt as if I were just pretending to exercise. Granted, the positions I was in were ludicrous, but I just didn't feel the burn.

Today is a different story. Ouch.

The jackknife will either make me so strong I will be able to rip phone books in half with my abs, or it will kill me.
