When I was in high school and saw Pumping Iron and started reading bb.com, I thought bodybuilding was the shit. I figured I could look like Arnold/Coleman and others one day by just lifting hard and eating right. As I got older and started reading, I realized that most guys are on enough gear to down an elephant, have no jobs, suck dick for money and are the most insecure pussies on the planet.
I even figured to compete once when I was younger. How naive I was.
I like lifting and exercising for the sake of it. It's just flat out fun to do. Jerking off to guys with thongs hiked up their ass and arguing over who had the best lat spread and ham/glute tie-in? Not so fun.
When I was 18, I wanted to be a solid 240-250. At 20, I wanted a solid 220-230. Now I'd be happy at around 8% bodyfat at 205-210.
To each their own, though. It's amusing to laugh at them, though.
