I pulled my left bicep a week and a half ago. It was feeling better, but just trying to some back work and now it hurts again, so it obviously wasn't completely healed. It makes me want to cry to think of losing ground with my biceps, let alone my other upper body muscles. It seems that when I try to do back, chest, shoulders, anything, my bicep is incorporated in some way. Anyone has suggestions for work I can do that will isolate well enough that my bicep won't be incorporated? And, I've been purposely not working the other bicep, so they won't get uneven. Does that make sense, or should I be working on the healthy one? I could really use some advice; I am so bummed.
