Jelly. My legs but more so my arms are burning and throbbing. Today was Day 1 of swim training. I am mainly taking swimming in hopes of toning up my body and generally to make me feel healthier. It's definately going to be a long road though. I think my swimmingg technique has a lot to be desired and if I could improve my storkes, it would cut down on the work. I never would have thought I would feel my muscles burn while submerged in water. And I never even thought of how thristy I'd get while swimming. Yowza. The best thing is that I didn't feel stupid about how bad I was doing, I felt more stupid for asking how it works to rent a towel.
