I have only been bouldering for about 2 months but after about an hour and a half my hands aren't too tired but my finger tips are soar and feel raw and I just can't grab holds. Is it cause I just started or does it go away after a while?

i know what you mean. my fingertips were all-soar when i started. i did use gloves, too, to relieve myself. after a while though i guess my fingertips got used to the, uh, pressure and i never had the same problem again.

I have just started doing indoor climbing, and i have to edmit i can hardly type now, my finger tips are killing me. I think i will move to wearing gloves as well, but any suggestion for type of excercise to increase the strength of my arms?

do you mean the skin of your fingers is raw, or that there is a soreness in the deeper tissue? if it's just a skin issue, i'd avoid the gloves (personally). It'll pay off when you build some good callouses, as well as the fact that there will probably be a time when you're going to want to take the gloves off to really use your hands.

as far as building strength in your arms, keyvanrahmad, there are a number of exercises. i love a good campus board for pull-ups and practice with different holds. metolius makes a nice one, that's not too steep for the price, or use a bar or branch. also, i actually have found those little grip exercise things (the ones you squeeze) to be pretty handy. but aside from those ideas, i think that the best workout is climbing itself and stretching.
