Was roughly 170 lbs for most of my teenage years (none if it was muscle) and didnt like the direction I was headed; I lost 30 lbs in the course of a year through some misguided dieting. Realized I had given myself a blank slate and decided to challenge myself with lifting.

The challenge of discipline, the feeling of a good pump, the freedom of diet (when bulking), and the steady accomplishment of goals, both in the short and long term.
