Z Press
The Z Press primarily works the Anterior Deltoid, Lateral Deltoid, Triceps (Long Head), with secondary activation of the Triceps (Lateral Head), Triceps (Medial Head) and stabilizer support from the Rectus Abdominis, Transverse Abdominis, Trapezius (Upper). It is a dumbbell compound exercise at advanced difficulty.
The Z Press is a advanced compound exercise performed with dumbbell, following a vertical push movement pattern. It primarily targets the Anterior Deltoid, Lateral Deltoid, Triceps (Long Head), with secondary engagement of the Triceps (Lateral Head), Triceps (Medial Head). This is a bilateral pushing movement, meaning both sides work together to generate force.
Seated dumbbell press with legs extended and back against wall increasing core demand.

Muscles Worked
The Anterior Deltoid, Lateral Deltoid, and Triceps (Long Head) are the primary movers, collectively driving the movement and absorbing the greatest share of the load. The Triceps (Lateral Head), and Triceps (Medial Head) act as secondary movers, assisting the primary muscles and contributing meaningfully to the overall output. The Rectus Abdominis, Transverse Abdominis, Trapezius (Upper) act as stabilizers, maintaining joint position and postural alignment throughout the movement.
Primary Muscles
- Primary Muscle Anterior Deltoid (shoulders)
- Primary Muscle Lateral Deltoid (shoulders)
- Primary Muscle Triceps (Long Head) (triceps)
Secondary Muscles
- Secondary Muscle Triceps (Lateral Head) (triceps)
- Secondary Muscle Triceps (Medial Head) (triceps)
Stabilizer Muscles
- Stabilizer Muscle Rectus Abdominis (core)
- Stabilizer Muscle Transverse Abdominis (core)
- Stabilizer Muscle Trapezius (Upper) (back)
How to Perform
Preparation
- Stand or sit with upright posture.
- Grasp dumbbells with firm grip.
Execution
- Press weight overhead until arms are fully extended.
- Lower weight back to shoulder level under control.
- Repeat.
Comments
- This is an advanced exercise.
- Ensure proper form before adding load.
Tips & Common Mistakes
- Keep your core tight and avoid excessive lumbar extension to protect your lower back.
- Don't fully lock out your elbows at the top — maintain a slight bend for joint safety.
- Control the eccentric phase; lowering slowly builds more strength over time.
Programming Suggestions
Adapt your sets and reps to your training goal. This is an advanced exercise — experienced lifters can push intensity higher and use more varied rep schemes.
| Strength | 3–5 sets × 3–6 reps at 80–90% 1RM with 2–4 minutes rest. |
|---|---|
| Hypertrophy | 3–5 sets × 6–12 reps at 65–80% 1RM with 60–120 seconds rest. |
| Endurance | 2–4 sets × 15–20 reps at 50–65% 1RM with 30–60 seconds rest. |
Alternative Exercises
These exercises target the same primary muscles (Anterior Deltoid, Lateral Deltoid, Triceps (Long Head)) and can be substituted based on your equipment or variation preferences.
