so i guess lean more forward when running? I just don't really
want to lean my head forward, cuz thts what a lot of joggers do to
get oxygen to their head, but it strains ur neck muscles. I may be
hyperextending my back though when i run. So posture is for sure
something ill try different. I think you're right about technique
actually. I realize that i run very flat-footed. Not using my
calves as much as stomping them down on the ground. So the
vibrations may have damaged my lower back? thanks, i think ill
stick to biking for now, and switch back to running in a month or
so lol.
