I've always loved to swim. Which is why we always belonged to a pool so that the family could swim and the kids could be in the swim team.
However, as I grow older, I'm also using swimming as an exercise, keeping the joints in shape.
My favorite stroke is the sidestroke. Lazy swimming on your side with your head almost out of the water. Next favorite -- backstroke. (same reason, easy to breath while swimming, lying on your back) All the other strokes (crawl or freestyle, breast stroke, butterfly) are just controlled drowning, in my opinion.
Then I made an interesting discovery. The sidestroke was great at trimming hips. Except for one problem. If you only swam on one side all the time, ONE hip trimmed down, but the other kept its secretary spread. hmmmmm.
So I began forcing myself to learn to do the sidestroke, lying on the other side.
Ah - problem solved.
