I keep getting pain in my left, whenever I do tricep extensions. I don't have this pain doing dips using my bench. I think I might be able to avoid pain, as long as I don't go all the way down and flex at the bottom, once I go all the way down it hurts, if I go just before all the way I still feel some pressure but it's manageable. What could be causing this and can I just not fully flex on the bottom and still get a good workout, or would that leave my tricep less developed? I have no elbow pain with any other exercise, I only have free weight, no cables. THe pain was worse when I was using an ez bar, now the pain isn't as bad but still there. The pain is just enough that I can finish a set but it hurts after ward and alittle the next day, with the ez bar I had a lot of trouble doing a full set.
