JM Press
The JM press is a hybrid between a close-grip bench press and skull crusher. With a shoulder-width grip, lower the bar to the neck or chin depending on proportions, bending the elbows and shoulders together to keep the elbows above the shoulders. Curl the wrists as you reach the bottom of the motion, and press back to the top without dropping the elbows.
Purpose
The JM press is a tricep strength exercise that emphasizes the medial head.
Programming
Generally sets of 10-20 reps are appropriate.
