Best way to climb a hill ..sitting down or standing up ?

CRankin,
it COULD be your bike. I remember when I switched from Bike A to Bike B (I don't remember which now) I was stunned that suddenly it was EASY to stand up!!
and if you are doing 20% grades, you are NOT puny. I am not doing 20% grades. or even 15%.. maybe 11 or 12 sometimes. for a few feet... eeek.

I'll second that it could be your bike. I've had several bikes that it was near to impossible for me to stand on a climb on, mainly because of the way my weight was distributed. In any case even on a bike that fits me I'm more of a sitting climber. I'll stand to power up short, steep hill or once in a while to stretch out my butt muscles on a long one, but for the most part I'm a seated climber.
