Ok sorry bout that. It kind of aches after push exercises, especially military press' , incline presses. But I'm fine with declines. It aches after I've done the set, say if I had my arm by my side I can feel a burning in my shoulder. I can lessen it by elevating my elbow slightly or putting something cold on it. It does slow down my workouts, as I wate for the burnin to ease. This can be pretty frustrating when I'm trying to train heavy.
Hope this helps
