Re: Interesting dynamic in my club
I notice this dynamic much more at seminars I attend, less so during class time. Then again, we are very small, a dozen members at our strongest, so there's really no option but to train with as many people as possible and mix it up during class.
I was given advice before my first seminar, which I think works well in this situation too. Try to train with as many different people as possible, and be assertive/aggressive with seeking them out. Possibly even scope someone out beforehand (while of course focusing on technique being demonstrated).
Just know that if you're going to be working with a senior student, especially one who may not know what level you're at, it can get intense. I remember giving a damn committed attack one time during a basic ikkyo, then being on the ground and not really knowing how I got there. My fault really, I gave more energy than I was prepared to deal with. Ah well, no harm done and it was kind of fun.
I know that, towards the end of a seminar, I can tell I'm dragging when I wind up sitting out a technique or two because I'm too tired to quickly find a partner. This happens more than I'd like, to my shame.
