after tearing up my knee, i was told by my physical therapist to do a lot of stretching. i started going to yoga, where i went from being by far the most inflexible person there to one of the more flexible people ... not quite up there with the dancer chicks, but certainly the most flexible guy. it also strengthened my core and improved my balance.
n.b., i do "power yoga", not much meditation but lots of core-activating postures.
