Lately I've been experiencing some pain in my elbows when doing tricep exercises (mainly skullcrushers and overhead tricep db extensions). Recently there has been some dicussion about proper form for these exercises having to do with whether your elbows should flair outwards or not. I've always been somewhat strict with keeping my elbows in, is this really the right way? Should I try these exercises with my elbows pointing out? Is there something else that could be causing this discomfort?
