I started rock climbing about a year ago and progressed pretty quickly but the tendons and ligaments in my arms have become a serious problem for me lately. They’re constantly sore and seem to be very injury prone. Are there any good techniques for training them, specifically the ones in the hands, wrists, elbows and shoulders?

I’ve looked around some body building forums but most of that was very technical and over my head. Hope someone can give me some more straight forward information. Thank you!
