Just to add more to the dialogue. From VeloNews "training" archives:
Why can't I climb?
Dear Joe,
I'm a recreational roadie who spends some time on a mountain bike as well. I've been actively riding for four years. I put in 100-150 miles a week, with mostly mixed rides - by virtue of living in remote Wyoming, I don't get many flat, easy spins!
Here is my challenge. I feel fit, but I cannot climb hills. I'm 5'11", approximately 160 pounds, resting HR of 44, no chronic illness, and I can't ride up hills! I do well on the flats between any rises, which means I make my pulls when riding with a group, I can spin around 22-24 mph, and am reasonably comfortable at that pace for many miles. But as soon as the pitch increases I shut down.
My primary riding partner, an ex-pro, has quizzed me about what my body feels like when this happens. Basically, I shut down. I don't feel pain, but I cannot continue riding at a strong pace. My muscles feel like they are not getting enough oxygen and my RR goes very high (never measured). I slow down to a slower pace, and push hard to the top - once there, I can pick my pace back up and have to fight to get back to a group. This has not improved, even with many miles on my bike and with consistent riding.
So, do I just need to train differently (strength, cardio), eat differently (change my intake before riding), hydrate differently, lose weight, or is there some underlying cardiovascular issue that could predispose me to being a sloth on the hills?
Thanks for taking a stab.

Dear J.R.,
Your inability to climb well can be improved if you find the key limiter and incorporate an objective plan to improve your fitness in progressive stages.
In most cases cyclists looking to climb better need to improve force and muscular endurance. You first need to have sufficient force in order to push hard on the pedals as the grade of the road increases. Ideally, the force-specific workouts are started within the preparation phase and end within the base phase. You can build force in the weight room with a cycling-specific routine and periodized program. Force can also be developed on the bike with low rpm (below 70 rpm), seated hill (or headwind) efforts. If you do force work on the bike, begin with two-minute efforts and progress, over several weeks, to six-minute intervals with full recoveries. Staying seated will also develop your hip flexors, which can help your climbing economy. Be cautious with these intervals if you have knee issues, or do not do them at all.
After you have developed sufficient force you can start to incorporate muscular endurance workouts by starting with six-minute intervals at heart-rate zone 3 (10-15 percent below lactate threshold). Gradually increase the number of reps within a workout over several weeks. Your goal is to progress to one solid effort of 45-60 minutes of zone 3 intensity. Once you have reached this goal, develop a workout once a week that incorporates heart-rate zone 4 (within 10 beats of lactate threshold) into six-minute intervals, with two-minute recoveries. This will dramatically improve your climbing ability if you have first developed force, economy and muscular endurance.
You need to determine which basic ability is lacking and what level of intensity you need to emphasize. The best way to improve your climbing is with a program that covers many months, starting with a preparation phase, moving to a base phase, and ending with a build period.
You mention body weight as a possible limiter. While I'm sure losing a few pounds might help, I don't think your 2.2 pounds per inch of body weight (you are 5'11" and 160 pounds) is of major concern. Assuming endurance is not an issue, and you have problems on climbs even early in a ride, this leaves the possibilities of economy (skills), force and muscular endurance to improve.
Thanks for inquiring with us. Good luck with your training.
