I haven't swum in a very long time, although I used to be able to swim with the crawl stroke pretty well as a kid. Now after a couple decades of not using that stroke my body has forgotten how. My body is getting beat up from running, and I need to change the type of cardio I get.
Problem I ran into last night, other than working on the timing of my breathing, was that I'd get about a third of the lap done and my calf locked up with cramps. Once it calmed down I attempted to swim again, with the same problem.
I can do the breath stroke OK, as that uses a different leg technique. I do want to get the front stroke working for me again so I can just crank out a good 500 Calories of cardio and be done.
