Go early afternoon to avoid the geriatric soup -they're all taking naps then. I miss diving into the outdoor pool, though -the indoor is 5' deep max. And I wish they wouldn't label one of the lanes as "floaters".
Swimming regularly makes a huge difference to your overall fitness and energy levels.
170 lb, would like to be nearer 140, but I think that's pretty unrealistic as I'm very well muscled (built like a brick shithouse is another way of putting it) and I seem set to stay this weight -I never gain any, but any I lose goes straight back on the minute I blink. Still, I can dream.... At least people are suprised when they find out how much I weigh -I guess I don't look it.
