Nice. So, I did disc 16 last night and on the final exercises, the triceps kickbacks, I tweaked something in my neck/trapezius on the first set. So what did I do? Yes, the rest of the sets. All of them. At the heavier weight. Within an hour I could hardly move my head. I'm an idiot. I'm hoping Advil and heat and ice over the next 48 hours will do the trick. I'm supposed to do legs tomorrow, but will push it to Sunday to be sure. Damn, this irritates me. I'm not even sure how I did it. My head must have gotten out of alignment - I don't know if I looked back, side, up or what. grrrr
