Z Press

Anton YefanovUpdated September 6, 2026

The Z press removes every source of leg drive. You sit on the floor with the legs extended and the torso upright, then press overhead to full lockout and lower under control. Because there is no bench and no knee bend, the trunk and hips have to hold the position while the shoulders do the pressing, which makes it a shoulder lift with a large core demand. The shoulders are the target with the traps and triceps supporting, and the front deltoid is the prime mover.

How to do the Z Press

Sit on the floor with your legs straight out in front and your torso upright.
Take the weight at shoulder height with an overhand grip and your elbows in front.
Brace your abdominals, squeeze the glutes and tuck the chin slightly.
Press overhead until the elbows lock and the ears line up with your biceps.
Pause at lockout with the trunk still vertical.
Lower back to shoulder height under control without letting the torso lean back.

Why train it

Trains overhead pressing with no leg drive or bench support available.
Forces the trunk and hips to hold a tall seated position under load.
Exposes limited overhead range that a standing press can hide with a lean.

Common mistakes

Leaning back to start the press, which turns it into an incline press and removes the core demand.
Letting the lower back round so the pelvis tips under, which blocks the overhead range.
Finishing with the weight in front of the head instead of over it, which loads the front of the shoulder.
Loading it like a standing press, which breaks the seated position immediately.

Frequently asked questions

What muscles does the Z Press work?

The Z Press trains the shoulders as the main target. Expect the triceps, traps, core, and chest to take some of the load as well.

What equipment do I need for the Z Press?

The Z Press needs a dumbbell. Nothing beyond that is required to run the movement the way it is described above.

Is the Z Press suitable for beginners?

With some training behind you. The Z Press is rated intermediate, which means the setup matters as much as the effort. It is a reasonable first month goal rather than a first session one, and the alternatives below are the easier way in.

Can I do the Z Press at home?

Yes, if you own a dumbbell. That is the whole requirement, and it is the reason this one travels well between a home setup and a gym floor.

How many sets and reps of the Z Press should I do?

Three to five sets of 6 to 12 reps. Sit at the lower end with heavier weight when you are chasing strength, and at the upper end when you are chasing size.

What are good alternatives to the Z Press?

Barbell Overhead Press, Kettlebell Thruster, and Band Lateral Raise train the same primary muscles as the Z Press. Pick whichever one suits the equipment in front of you.
