Bump.
What I am finding is that the secret to climbing is climbing. Form helps, weight helps, but the big key is getting out there at every opportunity and just doing it. I now practice on hills which are just no fun but their steepness builds strength and also make you realize mentally that you can do it. Earlier this week I climbed somer very steep grades during a nightly workout, my legs were jello but I had not exhausted my areobic fitness - a different kind of workout for me on the bike.
