Some cyclists recently recommended a climbing position where you grab the bars along the top, right on either side of the stem, and visualize driving your butt straight down onto the saddle in order to stabilize your hips & lower core. I've never quite been able to figure out if I'm doing it right, but my wife now swears by it.
