Anyway, next time you're on a steep hill, do as I described in that quoted post. Don't push down particularly. Instead, just rotate the pedals smoothly. Push forward at the top, hard, push down a little, pull back hard at the bottom, and pull up some on the backstroke. You'll find this very hard to do, but do it anyway. A few weeks of doing this and you'll notice positive results.

Another painful thing you can do is: on a slight grade, maybe 1%-2%, unclip one foot and pedal one-legged, trying really hard to keep a taut chain. Try to do that with each leg for at least 2 minutes. Ouch. But it works.
