Barbell Z Press
What Is the Barbell Z Press?
Barbell Z Press is a compound exercise that primarily targets the shoulders and also engages the triceps, upper back and the muscles of the trunk. It is an advanced-level movement: you press a barbell overhead while sitting on the floor with your legs straight out in front and nothing behind your back, so it asks for good overhead mobility, enough hip and hamstring flexibility to sit tall, and a trunk strong enough to stay vertical under load.
The lift is named after Lithuanian strongman Zydrunas Savickas, known as "Big Z", who used it in his overhead training. It has since spread from strongman into general strength programs, where it usually appears as an accessory after the main pressing work. Sitting on the floor takes away leg drive and the backward lean many lifters fall into on a standing press, so the bar only moves as far as the shoulders and arms can push it while the torso stays stacked over the hips.
The deltoids do most of the work, with the triceps taking over toward lockout and the upper traps and serratus anterior rotating the shoulder blades upward as the bar rises. The abdominals, obliques and spinal erectors hold the torso upright, and the hip flexors keep you from tipping backward. Compared with the Seated Barbell Shoulder Press, where a backrest holds you in place, the Z press demands far more from the trunk and is done with noticeably less weight. Sitting on a weight plate or bending the knees slightly makes the position easier to hold.
The Z press suits lifters who want stricter overhead pressing, those whose standing press breaks down into a lean back, and anyone who wants heavy shoulder work without tiring the legs. Build a solid, upright Barbell Overhead Press first, and if you cannot sit tall with straight legs, work on hamstring and hip flexibility with stretches such as the Seated Wide-Leg Forward Fold before loading the bar.

Instructions
- Set the safety pins or J-hooks in a power rack so the bar sits at about upper-chest height when you are seated on the floor, then load the bar.
- Sit on the floor behind the bar with your legs straight and spread slightly wider than your hips, heels on the floor and toes pointing up.
- Grip the bar overhand with your hands just outside shoulder width and your wrists stacked over your elbows.
- Sit tall with your chest up and ribs down, brace your core and lift the bar off the pins so it rests at the top of your chest.
- Press the bar straight up, moving your head back slightly so the bar clears your chin.
- Once the bar passes your forehead, bring your head through and lock your arms out with the bar over the middle of your head.
- Keep your torso vertical and your legs flat on the floor throughout; do not lean back to finish the rep.
- Lower the bar under control to the top of your chest and repeat.
- After the last rep, return the bar to the pins before you move your legs.
Common Mistakes
Leaning back
Tilting the torso back to finish the press turns it into an incline press and loads the lower back instead of the shoulders.
Rounding the lower back
Tight hamstrings let the pelvis tuck under so the torso slumps, which weakens the press and strains the lower back.
Legs lifting off the floor
Heels or legs coming up during a rep means the load is too heavy or mobility is lacking, and it can tip you backward.
Pressing the bar forward
Letting the bar travel out in front of the face instead of finishing over the head makes it harder to balance and stresses the shoulders.
Jutting the chin forward
Pushing the head forward as the bar passes the face strains the neck; move the head back slightly to clear the bar, then bring it through.
Using standing press loads
Starting with the weight you use on a standing press usually ends in a lean back or a failed rep, since the legs no longer help.
Injuries
Barbell Z Press is a medium risk exercise when performed with proper technique. The lower back and shoulders take most of the strain. Tight hamstrings let the pelvis tuck under and the lower back round, while leaning back to finish a rep bends the lumbar spine into extension under load. Limited shoulder mobility shows up as the bar drifting in front of the face, which loads the front of the shoulder and the lower back at once. If your legs lift off the floor mid-rep, you can lose balance and tip backward with the bar overhead.
Set the safety pins or J-hooks at upper-chest height when you are seated so you can unrack the bar without a big reach and set it down if a rep fails. Start with an empty bar or a light load, keep your ribs down and your torso vertical, and keep your heels and the backs of your legs on the floor. If you cannot sit upright, raise your hips on a weight plate or folded mat rather than slumping.
To regress, press from a bench with back support in the Seated Barbell Shoulder Press, or use the Landmine Kneeling Single-Arm Shoulder Press, which needs less overhead range. Progress by adding small amounts of weight while every rep stays upright, or by pausing briefly with the bar at the chest. Stop if you feel a sharp or pinching pain in the shoulder, pain in the lower back, or numbness or tingling down the arm, and end the set when you can no longer press without leaning back.
Frequently Asked Questions
- Q: Why is it called the Z press?
It is named after Lithuanian strongman Zydrunas Savickas, nicknamed "Big Z", who used the floor-seated press in his training and made it popular.
- Q: How much weight should I use compared with a standing overhead press?
Expect to use noticeably less, because your legs no longer add drive or stability. Start with an empty bar or a light load and add weight only while every rep stays upright with your legs flat on the floor.
- Q: What if I can't sit upright with my legs straight?
Sit on a weight plate or folded mat to raise your hips, or bend your knees slightly, so you can keep your torso vertical. Keep working on hamstring and hip flexibility with stretches like the Seated Wide-Leg Forward Fold and lower the support as your position improves.
- Q: Will the Z press help my standing overhead press?
Many coaches use it as an accessory for the Barbell Overhead Press because it trains strict pressing without leg drive or a backward lean. It works best alongside the standing press rather than as a replacement for it.
- Q: Do I need a power rack for the barbell Z press?
A rack makes it much easier and safer, since the bar starts on pins at chest height and you can set it down if a rep fails. Without a rack, getting a loaded bar to your chest while seated is awkward, so a dumbbell version is the more practical choice.
