JM Press

The JM press is a barbell triceps exercise that lives halfway between a close grip bench press and a skull crusher. Lying on a flat bench with a narrow grip, you lower the bar toward your chin rather than your chest, keeping the elbows tucked close to the body, then press it back to lock out. That bar path is what makes it work: the elbows travel forward as they bend, so the triceps stay loaded through a range where a normal bench press would hand the work to the chest and shoulders. It is a favourite of powerlifters because it builds lockout strength with a load the elbows tolerate better than a skull crusher does. Start lighter than your close grip bench — the leverage is genuinely harder — and keep the descent slow enough that the bar never drifts away from you.
