something that I have noticed recently is that some of the "faster" runners run with their hands down by their sides at hip level, moving only through a few degrees each pace... For my part, I am more of an elbows bent at about 90 degrees and push them forward each pace. What I want to know is, am I missing a trick here? Will I suddenly tap into some vein of form by changing my technique? it doesn't SEEM to do much for me, but perhaps I'm doing it wrong?
