I started doing some climbing sessions last week on the home wall. These sessions don't actually have too much climbing, mostly doing assisted pull ups and wearing my climbing shoes for longer than normal.
Its amazing the calluses you build up on the top of your toes to allow you to wear thight shoes. Getting better though, I graduated from my Saphires to my Anasazis last night. I'm not sure if I'm going to try banana shoes next (Dragons) or my stiff ones (Mesas).
