I play guitar as well as climb but when ever i climb i get this horrible joint pain in my fingers where it hurts to close my hands. I don't want this to affect either guitar or climbing so what type of warm ups should i use or does any one know any sites?

Well, you haven't actually said whether you get that pain before or after you warm up.. Do you jump on routes where you're forced to close-crimp before you're properly warmed up? If so, I recommend you warm up your finger by doing easy, open-handed climbing. LIke hanging on jugs etc. Then slowly start close-crimping stuff, but only when you don't feel pain. Basically, get enough blood flow to your fingers by warming up so that it doesn't hurt at all when you close-crimp. If it still hurts, then it's probably an injury. And injuries suck. I know this because I spend maybe 3 - 4 months a year, every year, injured. There's an interesting article on planetfear.com about warming up your fingers too. Hope that helps. dom
