I swam a lot as a kid as my mother was a lifeguard and instructor. Despite that, I was never amazing at it, probably because I was lean and had no buoyancy, but I loved it a lot.
I swam for the first time in years a few months ago, and was surprised how exhausted I was after 30 minutes of treading water! I work out and go on frequent long runs, but I was totally spent from that. I too would love to get into it again, it's definitely a great exercise.
Haha yes. Well, I'm pretty sure most pro swimmers are very lean and muscular (ie. not buoyant), so that's not the whole story. I was decent enough at swimming but never great at floating.
