No disrespect intended towards Egami Sensei, but if he had trained with the makiwara for 25 years and found it not only useless in developing power, but also detrimental to ones health, then he obviously did not train with it properly.
Hmm, yeah I was thinking the same thing. Personally, I feel that despite the fact that Egami Sensei was up there with the rest of the karate greats in terms of seniority and skill etc., he might not really have achieved the same level as the rest of them.
I've heard a quote from another karate sensei about makiwara training being for the hips.
Still, thanks.
