My Sports / Martial Arts Background

Growing up, I was a swimmer. I didn't do any other sports, so I don't think my senses of aim, balance, etc. are all that good. I'm active every day (I commute by bicycle). My endurance is good but I'm not good at high intensity exercise. I've always been rather flexible, and I'm fairly strong for my size (I guess at this point I should point out that I'm 5'2"). Several years ago I studied Wing Chun Kung Fu for almost a year before new commitments precluded my continuing study.
