When I do pull-ups, I feel I push down to the bar. But does the bar really take more weight than just hang down? For people who don't know pull-ups and hang down, here is an illustration. Left: H

To get the same torque, we need to use less force (hence less energy) with a longer lever than we would if we used a shorter lever (by the t = r x
