http://youtu.be/zZYzoKQspTwReggie, where is your elbow hurting? If on the outside that tiny little muscle that goes over the outside of the elbow is often confuse with a tendon and it is the muscle responsible for supinating during curls. Well for supinating in general but it sounds like to me if that is the issue you probably inflamed the hell out of it on biceps day. If so may I recommend using the EZ Bar almost exclusively for now when going heavy and only do really light weight curling in the supinated position. You can take the time to do some hammer curls andcurls to strengthen the supporting muscles. The EZ Bar allows me to keep lifting when mine acts up and it does regularly when I do a lot of supinated curls or BB curls. Even avoiding underhand rowing will help while getting the inflammation under control. Neutral grip and pronated grip don't really effect that part of the arm. Then again I may have wasted my time typing all of this because it may not be the same area but somebody somewhere will read it and find a way to work around a serious pain in the ass issue if not you.
