I started working out/dieting due to health reasons. I was a big dude (315 lbs. at one point) and I went to the doctor's office and they told me to lose weight or I was in serious danger of developing health problems. I started dieting and running a lot and around 10 months I had already lost 100 lbs. After one year, I lost 116 lbs total (dropped from 305 lbs. to 188). I started lifting just to look good and try to regain my lost strength but now I do it because I love it.

Its fun.
