J-Presses do it for me. If you have a smith machine, do them after your chest day. Flat bench, narrow grip, only go about 2/3 of the way down to your chest and keep your elbows at a 45 degree angle away from your torso. If you keep your elbows there, and sort of push forward with your hands as you go up you get an insane contraction/burn down near the elbow. After a few weeks of these, my tricep bulged out almost like my bicep above the elbow! Good luck!
