Have to work on those abs

I made a little progress on abs over the past few weeks. I've been in some pretty sad shape over the past year or so. A few weeks ago I found myself barely getting through 30 crunches before my legs started to drop. Today I finished 60 per ab set! I'm feeling empowered to prove to myself that I can still achieve my former times. I'm going to make it happen.

Strong abs will help me with my underwater kicking and will help maintain my form while swimming. This is especially true in backstroke. A weak core causes your midsection (read: butt) to drop in the water and obviously causes more drag. A strong core enables you to remain straight in the water.
