Well they were both with a local instructor who shall remain namelessThat must have been an uncomfortable situation, Paul. If I may, what were two bigger wastes of time?
The second worst was on a seminar and we spent an hour doing oi-tsuki. Don't get me wrong, nothing wrong with oi-tsuki, great technique for certain situations, I like it. But he didn't actually teach anything, we just repeated it, over and over. No explanation of where and how you would use it. It was a seminar ffs, not a karate lesson, think someone forgot to tell him that. I learnt nothing, not a thing.
Biggest waste of time was the same guy. Another seminar, year before last I think it was actually. 50ish people in the room. He spent an hour doing head kicks even though he was the only one in the room flexible enough to do them. I don't see the point of that, an hour doing techniques no one else in the room is physically capable of doing without tearing muscles tissue. He either wasn't paying attention to the people he was supposed to be teaching, or didn't care. Again, learnt nothing.
I given that seminar a miss the last two years needless to say.
