A friend from pre-calculus class asked me to lift with him, after he heard I'd recently started some calisthenics, with another friend, randomly. I went once with them, then switched to weights from calisthenics after talking to a few people.

Bodybuilding enhances your total physical well-being. Every day I work out, I feel much more energetic and good in general at work the rest of the day. It builds self-esteem, as I get stronger through hard work. Looking sexier isn't a bad result either!
