My English is really damned bad.
I entered the discussion, because I did not really understand the question. Something was wrong.
Paige's reply brought me to the idea but I had to read it 3 times again to get it
"To what extend is it under your control, how tired you get in your aikido training?"
And I thought, making sentences difficult was typical for German. Especially for those German, who had some Latin classes.
Usually I am exhausted, at least at the end of the training and I should be able to get it under my control, right breathing, doing the exercises fluently but without hectic, etc.
But after the training, sitting in the train to get home, I am not tired at all. At least much less than going home directly after work without training.
