Someone on this board once posted "boobs to the tube" with regard to hill climbing (meaning lean forward). When I do that, and keep an easy, loose grip on the bars, that really helps. (In fact, I find myself saying it over and over in my head as I climb: boobs to da tube, boobs to da tube! ) Don't remember who said it, but it stuck with me, and it does work.

That, along with not looking up at the hill you're climbing (just look far enough ahead to keep from crashing into something) are the things that help me get up those #@% hills.
