Hi, I know we have at least one or two rock climbing superstars here. I am tentatively interested myself, and have a few questions to start out. We have some indoor walls here in Boston, and that's probably enough for me, since I'm pretty nervous with heights. It's kind of an indoor fitness for winter/activity with hubby type of thing.

First, I'm not in too bad cardiovascular shape and am building muscle, but do I need to be close to my ideal weight to start out?

Does RC provide a decent workout?

Would it be better to avoid this if I have an old shoulder injury? I could ask my physical therapist, but your opinions would be helpful too.

I'm sure I would come up with more questions later, but thanks a lot!
