Had my first go at climbing on an indoor wall last week, and went again last night. All I can say is it's absolutely great for conditioning, and a nice bit of exercise variety. Today I can feel my shoulders, lats and arms, so am definitely hitting the right areas.
And for anyone who likes to harp on about 'functional strength', I'm a bit of a joke at the wall because as a climbing noob with little technique I tend to haul myself around with my arms a lot.
A lot of my friends are amazed at how well gym strength translates into climbing strength. I think I've managed to sway the opinions of some friends who before could never understand why I "spend so much time in the gym JUST lifting weights".
When my finger strength goes on some of the harder routes, I like to try and zip up and down the easier routes with the big holds as fast as I can 2 or 3 times in a row. Great for conditioning. Sweating like mad by the end, and can really feel my entire upper body. Great stuff.
Anyone other T-nations into climbing? Maybe even some awesome outdoor stuff?
