I agree with all that's been said. Fitness, and learning what gear to use when first attacking the hill, how & when to shift on hills (you don't want to try to shift a chain under tension) all play a roll in getting up the hill. I ride occasionally with a person that is struggling before they try to shift-they are shifting too late for the benefit of a lower gear. When you feel yourself starting to put forth more effort than you should, shift to an easier gear--maybe a little before you THINK you need it. Eventually you'll learn when it is most beneficial for you to shift to get up the hill. It may take a while, but you'll get it. Keep at it, you'll be climbing up those hills before you realize it!!
