The Z press is an overhead press performed sitting on the floor with legs straight out in front. The seated-floor position eliminates all leg drive and forces the core, hip flexors and shoulders to stabilise the lift. It’s the ultimate strict overhead press — no cheating possible.
What it is
The Z press is a strict overhead press performed seated on the floor with legs extended in a Z-shape (or L-shape). The lifter presses a barbell or dumbbells from shoulder height to overhead lockout. The floor-seated position removes any leg or trunk assistance, making it the strictest press variant.

How to Z press: 5 steps
-
Sit on floor
**Sit with legs extended forward in a Z or L shape.** Barbell or dumbbells at shoulders.
-
Brace
**Torso vertical, core tight, quads engaged.**
-
Press up
**Press straight up to full lockout** — no trunk lean.
-
Lock out
**Arms extended overhead, torso stays vertical.**
-
Controlled descent
Lower over 2-3 sec to shoulders.
How it differs from OHP
- Floor-seated with legs extended. Zero leg or trunk help.
- Massive core demand. Hip flexors, abs, obliques all fire hard.
- Requires hip and hamstring mobility. The seated leg-extended position exposes tight hamstrings.
- Much lighter loads. 60-70 % of standard OHP weight.
Common mistakes
When to use this variation
Use Z presses to expose weaknesses in your press and build strict overhead strength. Program 3 sets of 5-8 reps. Excellent for building an unfakeable overhead press. Pair after main OHP work as a diagnostic accessory.
FAQ
Barbell or dumbbells?
Both work. Barbell allows heavier loads; dumbbells allow more range. Try both.
What if my hamstrings are too tight?
Sit on a low box or plate to raise the hips slightly. Work on hamstring mobility separately — the Z press exposes what needs fixing.
Z press or seated DB press?
Z press is more demanding (no back support, no leg drive). Seated DB press with bench is more accessible. Use Z press as a specialty tool.
