A bench and skull crusher hybrid that hammers the triceps.
Keep the bar path tight to your neck, it's a tricep press not a chest press.
The JM press splits the difference between a close grip bench and a skull crusher, letting the elbows drift forward so the triceps take the load through a range where they can handle serious weight. The chest assists just enough to let you go heavier than any pure extension movement allows. It exists for one reason, building a lockout that does not fold under heavy benches.
A close grip bench keeps a normal press path with the elbows tracking down by your sides. The JM press deliberately lets the elbows drift forward and the bar travel toward the upper neck, turning it into a hybrid that isolates the triceps far more.
Skull crushers isolate harder but limit how much you can load and can nag the elbows over time. The JM press lets the chest chip in so you can overload the triceps with heavier weight. Many lifters rotate between the two.
Toward your upper neck or chin area, stopping when your forearms are near vertical, not down to your chest. If the bar keeps landing on your lower chest, you are just doing a narrow bench press.
