Shoulder Press Machine
The Shoulder Press Machine primarily works the Anterior Deltoid, Triceps (Long Head), with secondary activation of the Lateral Deltoid, Pectoralis Major (Clavicular) and stabilizer support from the Rectus Abdominis, Serratus Anterior, Transverse Abdominis. It is a machine compound exercise at beginner difficulty.
The Shoulder Press Machine is a beginner compound exercise performed with machine, following a vertical push movement pattern. It primarily targets the Anterior Deltoid, Triceps (Long Head), with secondary engagement of the Lateral Deltoid, Pectoralis Major (Clavicular). This is a bilateral pushing movement, meaning both sides work together to generate force.
Press the handles overhead while seated in the machine.

Muscles Worked
The Anterior Deltoid, and Triceps (Long Head) are the primary movers, collectively driving the movement and absorbing the greatest share of the load. The Lateral Deltoid, and Pectoralis Major (Clavicular) act as secondary movers, assisting the primary muscles and contributing meaningfully to the overall output. The Rectus Abdominis, Serratus Anterior, Transverse Abdominis act as stabilizers, maintaining joint position and postural alignment throughout the movement.
Primary Muscles
- Primary Muscle Anterior Deltoid (shoulders)
- Primary Muscle Triceps (Long Head) (triceps)
Secondary Muscles
- Secondary Muscle Lateral Deltoid (shoulders)
- Secondary Muscle Pectoralis Major (Clavicular) (chest)
Stabilizer Muscles
- Stabilizer Muscle Rectus Abdominis (core)
- Stabilizer Muscle Serratus Anterior (chest)
- Stabilizer Muscle Transverse Abdominis (core)
How to Perform
Preparation
- Stand or sit with upright posture.
- Adjust machine seat and pads to fit body.
- Sit or position body in machine.
Execution
- Press weight overhead until arms are fully extended.
- Lower weight back to shoulder level under control.
- Repeat.
Comments
- Maintain control throughout movement to fully engage the Anterior Deltoid, Triceps (Long Head).
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. As a beginner-friendly exercise, start with lighter loads and focus on form before progressing weight.
| 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, Triceps (Long Head)) and can be substituted based on your equipment or variation preferences.
