So I suppose 6000 front kicks to belt level in an hour would be a bit much too? I stopped doing them past 1000. It was okay once when we built up to them in a year's time but just to do 3-4000 on a whim hurts the hamstrings. Its called overuse.
I remember once he lined us all up (as a blue belt) and informed us that if we have an injury, too sore or whatever, don't come to class. In other words don't complain or even mention it or you can't come to class. Gosh, that would have X'd out most of us 40 plus which was basically his class.
But the last two years, when he asked for an exercise that I knew would not be good for me, I either did less or substituted it. I tell him my injuries and why I can't though. Didn't seem to matter that I had a bad hamstring, we would be asked to do double front jumps or all high kicks that day - hundreds of them. I got wise real fast. Do what you can - healthwise.
But I had a GOAL, to get the 2nd dan that he was actually discouraging me from going for. So THAT is why I bit the tiger by the tail and hung on. What would you do if someone denied you your right on personal reasons-wrong reasons, and you had just a hairbreadth more effort in the break to get to your goal? I cracked that top board three times but no, he wouldn't take it as broken but then he substituted it for a blind fold jumpspin heel for the next people testing. Hey, I already do that without looking. TW
