My body never liked running. Even in Elementary school I was the slowest runner, although I didn't hate it like I did a few years later.

Swimming though, I love. So much easier on the joints. Nowadays I do water aerobics. Classes or else just on my own. I can get my heart rate up well beyond walking, do sprints, and do resistance training all in the water.

Getting harder to get in the pool since it is (finally) beginning to cool off in S. CA.
