In reply to fiveknuckle:
Your work mate sounds a little insecure. This does interest me though because I'm often suprised at how strong climbers are sometimes not that strong in general terms.
I used to work out in gyms a lot when I was younger and am still occasionally seen in one lamenting my physical demise.
Simon's right though, it depends what type of strength you're talking about. I used to train in a gym where there were quite a few guys bench pressing over 180kg. One guy managed over 240kg, which was well over twice his bodyweight. Can many climbers do that? I doubt it. The world record is over 450kg I think...check this bloke out
Not only pretty strong but a fashion guru
Strength training in a gym will generally make your muscles bigger and stronger than climbing. If you factor in strength to bodyweight ratios however the picture is less clear because training for powerlifiting will make you bulk up thus reducing your ratio. As we alll know the limiting factor in climbing is a very small muscle group (fingers and forearm muscles/tendons) which struggle to keep up with very high bodyweights.
Climbing strength is very specific and most pronounced in the fingers back, biceps, core and shoulders. In my experience, when comparing the strength benefits of climbing over weights, with some exercises related to those muscle groups (like deadhangs, campussing, pull ups, lock offs etc) climbers are often better than gym heads (relative to bodyweigtht), but that's about it. That powerlifter I mentioned before could do a massive five pull ups - pretty shameful.
