I'll second the core strength, and one-up on the upper body.

Last season I never stood to climb. It felt goofy and I always felt like I would pitch over the bars. I didn't do it. I was literally afraid.

This year, after spending 9 months in boot camp, and gaining some hard muscles, I stood right up on my bike without even THINKING about it. I got to the top of the hill and was so surprised and proud of myself! I mean, wow.

So gear down, do some biceps curles and get after it!
