I don't lift weights because I simply can't afford to get any bigger. Not that I'm ripped now, but for 21 years while I was still growing, I was always buying new clothes. Now that I've kind of fit into a nice, comfortable size, I'm not about to lift weights to build muscle mass. I worry about what will happen should I ever decide to stop lifting.

I really just enjoy the cardio. Besides, if I bike hard all year, I can ski like a maniac in the winter and not get tired all day.
