I think one of my biggest changes is in jogging. I have never been much of a runner. You can thank bad genes on that one. My family has always had iffy knees and lower back problems. Last year I trained for a 5K, and two months afterwards had to start seeing a chiropractor. Apparently the jogging was the culprit. Over time I went from seeing the chiro 3 days a week, to once every two weeks if I was lucky. But it wasn't until I started riding seriously that I noticed a change in the health of my body. Chiropractor visits are almost nil. I started jogging again and have more endurance. And the biking keeps my lower back from stressing from jogging.
