Doing pull-ups may only encourage poor technique, especially when ice climbing, if that's the only thing you're doing. Most of the time you're either hanging or locked off - not pulling up with your arms. You're much better off training by splitting wood, framing a house with a heavy hammer, etc, etc. You're forearms will flame out a heck of a lot faster than your back.
Hey Caveman - you need to step up to the 40 ouncers and drop the girlie weights.
