You've probably seen pro cyclists climbing steep grades, rocking their torsos side to side and downwards on each pedal down stroke. They are using the upper bodies to put as much force into the pedals as they can. They're also using their arms to move their torsos.
Just today, I went up a short but steep grade with a fairly high gear, in the saddle.
With hands in the drops and chest leaning over the bars, I was rocking my shoulders side to side, pulling gently back on the bars on each pedal stroke. It felt powerful, and I made it to the top without dropping my cadence. I couldn't have done that without the use of my torso and arms.
Watch this cyclist use his upper body to climb a super steep grade:

I realized today, and I think this video bears me out, that I'm pulling on the bars in part (at least) to counteract the sway in my hips as I climb. Definitely helps generate power.
