Hi-
Yep, I've just become a swimmer ( for exercise) this year!! While I have always been a "water baby", I am currently training for a triathlon so its necessary.. I love it.. its such a great way to get a workout that's non-impact. Such a different feeling workout compared to running, step, etc!!
It took me about a month to feel this way though.. before I got my rhythms down for the breathing, it would really wipe me out. Now that I have figured this out, its been much easier. I do wish they made waterproof I-Pods.. swimming laps gets pretty boring after awhile with nothing to listen to or look at ( other than a line at the bottom of a pool)
Are you thinking about starting to try and do it?
Take care, Lynn M.
