OK, that was a good workout. There was another green belt that had just come back from a fifteen-year break!
The only problem with the people at tonight’s class was that most of the dudes are 20-40 lbs. bigger than me. Besides the randori challenge, it made bridging my partner off of me really hard, and I pulled some weird rib muscle that I didn’t even know existed (the inner intercostal rib muscle, apparently). It was so foreign that I thought I broke a rib for a second? But it was OK, if sensitive, later.
Then in uchikomi (where you do the hauling up part of the throw, but not the dropping part) and nagekomi (where you repeatedly throw each other), I eventually strained my groin (the adductor longish, maybe?) holding up a big dude on one leg doing harai goshi and had to bail on those a little before the end, too.
I did get a couple rounds of randori in without incident.
Well, mostly. I went with a tall white belt that was really hard to move, so I ended up throwing him with kouchi makikomi and tani otoshi, then was reminded they said not to do that to white belts. In my “WTF can I do against this guy” state, I forgot.
I made myself do another round even though completely gassed so I hope to do two rounds next time. I went with a green belt that wasn’t as large and actually got a counter osotogari in, and he threw me with a drop seoinage that was slow, yet I couldn’t stop it. That round felt better because I didn’t have to try to work around a stiff arm.
Anyway, it was satisfying despite the obscure muscle pulls.
