Borked

This morning I made it to the physio-coached gym session. I took it easy, but I've still been really broken ever since. A nerve in my neck is screaming at me every time I turn my head, and my back feels all sorts of wrong. Urgh.
Discussed with physio the fact that I've never felt anything even remotely like what people describe as an endorphine high. I always just feel tired and achy afterward. Sometimes satisfied and tired and achy though. The best moment about exercise is when you're allowed to stop (I used to describe endurance competitions like that - it feels so great when you get off the horse afterward) but apparently that's not the same as an endorphin high.
