As many of you know, I enjoy exercising in a number of dimensions - PT for my back, weights and resistance exercises, walking, bicycling, stretching and swimming.

I didn't start swimming until December, 2007. I could swim a bit, but never knew how to really do the strokes, etc.

A couple of interesting things.

1. I have been swimming with two guys who have a goal of a triathlon, but have never done much swimming. They are both absolutely amazed at how different the aerobic requirements are for swimming as opposed to running and/or bicycling. Yesterday, one of the guys - likely in his late 20's, remarked that he could run 5 miles easily, and bicycle 20+ miles, but could not swim the length of the pool. Ditto for the other guy.

2. I found myself giving swimming tips to both these guys - at their request. I never considered myself a good swimmer, but I have folks frequently state that I seem to just glide through the water!

So, here I am at 70, having only been swimming two years, giving swimming tips to folks in their 20's and 40's.

BTW, I am trying to increase my bicycling length of riding. However, today, after an hour of PT and resistance training, 2 miles of walking and 45 minutes of swimming, my leg just sort of wore out in the store - the result , of course, of my stenosis and other back problems.

Aargh!!

Any other swimmers or all-around exercisers out there today?
