I think I've made the commitment to myself that I would work on my abs every spring since I was 13. And, every summer since I was 13, bathing suit season has snuck up on me and my undefined core with a taunting heat that says "feel comfortable in a bikini YET molly!?" to which i respond "i want pizza."
Maybe this spring will be different since my life basically depends on it - I know I can make it to mile 18.3... I'll need my rock hard abs to pull me through to mile 26.2.
