I'd like to know some good stretching routines for MA(karate). At the moment i just do what feels like alright, but i'd realy like to get better routine. I can just barely kick to my head, so i'm not extreamly flexible, but not stiffest either.
Being able to kick over your head is more a function of leg strength and kick mechanics than stretching.
That said, stretching more can only help. I've had people recommend Stretching Scientifically by Thomas Kurz, and Ultimate Flexibility by Sang Kim, but I've never gotten around to buying them.
