This is not the seminar you're used to. We may, maybe, but probably not, do a pushup, or a situp. Or 10 whole punches in a row. We won't do a thousand of anything, we will tire your brain. You can look after tiring your muscles.
The seminars will cover movement & partner drills as they relate to the Goju Ryu katas. For Zen Do Kai or Kyokushin participants, they're similar enough, but not quite the same. Expect there to be some differences there. Having said that, there is unlikely to be a lot of focus on the kata themselves and more on the applications and partner drills that go with them. You'll find similarities though at a fundamental level in terms of body posture and also in terms of body mechanics, like how to generate power for the strikes in the katas. There will be a lot of seniors with experience of Taira sensei's method at the Dunedin and Auckland seminars. There will be no shortage of people to help you.
