Elbows Out Extensions: This is one of the best movements for the lower part of the triceps. If you ever get a chance to see a great bencher, look at the mass around the lower upper arm, right above the elbow. This is where the big benches come from, not the upper part of the tricep.
The elbows out extension is designed to bring this area up to par. To perform the movement, press the dumbbells to the starting position above your chest. You want to keep the butts of the bells together as you lower them to your chest, keeping the elbows out. Pause on your chest for a second then press and extend the bells back to the starting position making sure to keep the butts together. This movement can be performed on a flat bench or incline.
JM Press:This exercise is like a close grip bench press mixed with a triceps extension. Start the exercise the same way you would a close grip bench press except make sure the bar is set in a direct line above the upper pecs. If you were to run a plum line from the bar down to the upper pecs, this would be the path the bar is going to follow. Lower the bar down this line until you reach about halfway down. At this point let the bar roll back about one inch, then press the bar back up.
