I need better legs

[indysteel]

I tend to agree with bluebug. Not that I don't think resistance training can be helpful, but what actual climbing allows you to do is work on leg strength, aerobic and anaerobic capacity, and technique. It also helps you build some confidence, which plays a role in climbing.

ETA: I became a strong climber even with a triple. I think it really depends on what kind of hills you encounter on a regular basis and what your knees and leg muscles can handle. I cared less about what gear I needed to use, and more about developing effective technique and a positive I-can-do-this attitude.
