I downhill ski raced in high school and had to work out for that, but I think I started working out for myself my senior year of college when I started getting into martial arts and weight lifting. I found I really enjoyed it and have been doing some exercise ever since. I got rededicated to really working out hard about 3 months ago when I realized I was gaining weight even though I was "working out"

Working out elevates my mood and it helps that I begin to like what I see in the mirror more and more. Also have to stay one step ahead of my prey :)
