I just arrived at my parents' tonight. They have a swimming pool. I was very hot from the drive through the Central Valley so exercise I was already planning on doing sounded even better. My RSI is so bad right now that I even have to be careful swimming. I did a couple laps of breaststroke interspersed with backstroke (not using my hands much) thrashing my legs as much as I could. I used the water as resistance for exercise for both my legs and my arms/lats. There are a lot of things about being at my parents that are going to drive me nuts. But I'll be doing my best to take advantage of the good things.
