When I was about 15 I actually started, but with much misdirection. I was pretty damn overweight and I was just tired of it. I made it into a phase type thing: phase 1 was to slender down, phase 2 was to get used to my weight, and currently phase 3 is to bulk back up. I finally got serious as i moved into my first year of college.

the feeling of being healthy, becomming stronger than I've ever been, and to become even more wise about the body's limits and composition as I advance in the martial arts
