Hi,
I read an interview with Uehara Sensei of Motobu Ryu where he advocated walking backward on the balls of feet as an important exercise. Some place else i read that in general Japanese walk backwards more often than westerners. Could anyone comment on how common this heels of ground walking backwards is in martial arts? Also is it common in with among Okinawans or Japanese not involved in martial arts?
thank you
Len
