Had another session yesterday, different trainer, different exercises, muscle aches in all new places today.
No idea what all those muscles are called, but I just found out they're exactly the ones you use when grating cheese. Good thing I grate cheese a lot, or the muscle ache would likely have been worse.
This time I took a modest amount of insulin 25 minutes before starting, and added some more halfway through when I hit 11 again.
Still, while the peak is as high as last week, it lasts shorter so I'll try injecting a bit earlier and a bit more next time, walking the tightrope of timing between insulin action and liver dump.
I don't really mind peaking if it lasts this short, but it does make exercising hard, feeling like I'm working through syrup. Not what I want when the exercise itself already makes me feel I just want to lay down and not move.
I'll get there, although maybe not before hitting a hypo from mistiming, we'll see.
Bonus points for the new trainer.
After the lesson I told him how the second half of the lesson was harder because of BG much higher than I'm used to, and he asked what type I had, never assuming I'm T2 because of age or weight. (More clued up than my GPat the time I guess.)
He seemed to know what he was talking about too, and had a good laugh over me promising to share my winegums if I got the timing wrong next time, not worried at all about possibly having to deal with a hypo in one of the people training with him.
I've never needed help for a hypo thankfully, but I'm pretty sure this trainer won't make a fuss if I take a time out and tell him to leave me alone, no talking while hypo, which is a very good feeling.
(edit: ignore that hypo later in the day, that was a stupid miscalculation, nothing to do with the training.)
