My problem with swimming is, as I already have a larger frame, it is hard to get wetsuit to fit me. Now, the wetsuit that fit me last year, no longer fit. Just the little muscle that you put on in a few week with a new exercise can change your wetsuit fit. Fortunately, I got a hyperstretch a few months ago, and that will accomodate me well.
Whew, got 22 laps in this morning (1/2 mile) in under 30 minutes ... That is a tremendous improvement from choking and gasping to do 2 laps at a time 3 weeks ago. You noted my post earlier, the old ladies were swimming circles around me. Now I am starting to keep pace with the old ladies...
