Hey there. I have been cycling and bodybuilding (both at the same time) for 30 years, so I believe I am uniquely qualified to answer your question. Simply put, it's not a matter of too much muscle or being to heavy to climb well. It's all about "strength to weight" ratio. In other words, if you weigh 220 and can squat 530 and another guy weighs 150 and can squat 375, then you both have the same S--T-W ratio (you can both squat 2 1/2 times your bodyweight). Bigger guys have a lot of power, but they don't always use it efficiently. You must learn how to use the proper gear on a climb. Chances are you won't be turning the cranks as fast as a "skinny minnie" would, and that's okay! Learn to use your upper body as well, which means to pull on the same side of the bar as your pushing with the pedal. Use that upper body! So, to review: 1. Get as lean as possible (forget about your bodyweight, focus on bodyfat). 2.Work on increasing your stregth overall, but especially in your legs, upper arms, upper/lower back. 3. Do A LOT of hill work and work on different techniques (seated, standing, slow and fast cadence). Good luck!-bikerray
