So, I went to the "muscle pump" class at the gym again today, and, boy, I was really dragging. It was quite a struggle to keep up. It was weird, too, because it wasn't like my muscles were sore or I was lifting too much weight. My body just didn't want to move. The stamina wasn't there.

I struggled through, though. It wasn't the most fun workout that I've had lately, but, hey, I made it.

It was just weird, 'cause on Tuesday, I had a terrific workout - I stepped up to slightly bigger weights and still managed to do the full set of reps on most of the exercises. I was starting to think, "Hey, maybe I'm getting the hang of this." Today's workout was clearly designed to keep me from getting cocky.

Some part of me wonders if I had slightly crappy workout because I didn't eat enough breakfast, or because I shorted myself slightly on sleep or something. Or if it's hormones. Or if once in a while I'll just have a crappy workout for no good reason. There's an awful lot I don't know about physical fitness. I'd actually like a good book on exercise physiology or something, but every time I go to the fitness section of the local Borders, it's all full of books with titles like "BUNS OF STEEL, ABS OF DEPLETED URANIUM." Who wants buns of steel? I gotta *sit* on these puppies.

Well, I suppose if I have this problem again, I can ask the instructor for the class. She seems like the kind of person who would give sensible advice and not try to sell me expensive nutritional supplements.

Okay, back to work for me. Later.
