Around 4 this morning I awoke from a dream in which I was trying to put separate parts of myself into individual boxes, frustrated that one part of my arm would not come off. When I was more aware, I realized my right tricep was really, really hurting. I'd been sleeping on it, but also the muscle was painfully tight. The left arm also hurt, but less so. I took an ibuprofren and went back to sleep.
It was still bad this morning, as in I couldn't comfortably bend my arm. I took 2 more ibuprofren and had a hot shower, which improved my range of movement somewhat. I am hoping it will ease as the day goes on.
I am fairly sure which exercise caused this pain - it was a triceps thing I'd never done, in which you lie on a bench and move the weight back over your head. Also, there were some pectoral exercises for which I know I used too much weight (my pecs are also still sore, but upstaged by the tricep).
I'm taking tonight off from the gym to visit the Adorable Tots, but I might have taken tonight off anyway.
Still pondering if taking classes this semester would be a good thing. I know now if I do BodyPump I need smaller weights!
