Muscle Group: Triceps
The JM Press, named after J.M. Blakley, coined by Lou Simmons, works all three heads of all of the triceps. JM pressing takes the shoulder completely out of the movement.
This exercise is like a close grip bench press mixed with a triceps extension, but with variations on both.
- 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.
- Beginning from a fully extended position. Lower the bar down till you reach the halfway point. Now, let the bar roll back towards your face, then press the bar back up.
This exercise is better demonstrated on video than can be explained by words. Lee Hayward demonstrates the movement below:
