I've never been rock/wall climbing before, and I've been thinking of giving it a try since there's a climbing wall here at my college. I'm sure that it's a great exercise, but I was wondering what specific benefits to expect. I'm sure that your grip, forearms and biceps would strengthen since you're always holding and supporting your body weight, but what else? I really look forward to exercising with such a wide range of motion. Since I'm a beginner, I'll be climbing slowly and deliberately. Is rock climbing considered cardio also?
