I've recently started doing a lot more horse and other painfully low and slow/static stances. From I thought about fast-twitch and slow-twitch muscle fibre, this should not increase my overall leg-strength... BUT I seem to be noticing a big difference in for example running up the stairs, and kicking. Why should this be? I don't eat shredded wheat, and as far as I know I wasn't completely mr-puny-can't-run-up-the-stairs couch potato beforehand either!
