Re: It Had to Be Felt #7: Yamaguchi Seigo: Suburi with People
I never had the opportunity to train with Yamaguchi Sensei. I did study for quite a few years with Gleason Sensei, one of his most prominent American students. Gleason Sensei once said that Yamaguchi Sensei's response to pretty much any training injury was "you were too tight."
Which illuminates one of the big challenges of ukemi, IMO: if you're completely accommodating, you won't get hurt, but maybe your ukemi isn't very martial. How do you preserve the structure you need for reversals, followup attacks, etc. while maintaining the relaxation and responsiveness that keep you safe?
I'm not sure, but I think having the appropriate balance at all times may be equivalent to mastering aikido.
