I've climbed most of my life...
I boulder three times a week and run 30 miles worth of trails a week . I can do pullups from my finger tips on a 'hangboard' (it's a training tool).
I climbed a V5 last week and was so happy I nearly cried.
These people are freaks in the most awe inspiring and amazing way I can possibly imagine.
Climbing competitions are worth watching just for the sheer amazement at what the human body can be trained to do. I use them at the beginning of classes because students usually just stop talking and watch in stunned silence.
