I was always flexing as a kid, I was stocky and loved having a little muscle. I also had gyno at the young age of 12 and I thought if I got bigger it would go away. I responded very well to lifting and loved it. Unfortunately the gyno never went away, and wont without some surgery.
Why I Love it
I never feel as good as I feel when I look in the mirror and see something I am proud of staring back. No other activity has as traceable results or is as continously rewarding. You can always set a new goal and work at it and monitor your progress easily. It just makes me feel great. I dont feel complete without working out.
