fftopic: but I was more interested in the bit after that:
"I started to straighten up my body. Actually I was hunched. I thought because of my backside muscles got too big since I started climbing, I wanted keep my chest and body open to extending my reach. But it took a year to get better."
How do you do this? I thought hunched shoulders were an inevitable part of being a climber. I generally do some shoulder opening stretches after a session but I'd resigned myself to it never being enough to counteract all the hours of squeezing beforehand.
