Machine Chest Press
The Machine Chest Press primarily works the Anterior Deltoid, Pectoralis Major (Sternal), Triceps (Long Head), with secondary activation of the Pectoralis Major (Clavicular), Triceps (Lateral Head), Triceps (Medial Head) and stabilizer support from the Pectoralis Minor, Serratus Anterior. It is a machine compound exercise at beginner difficulty.
The Machine Chest Press is a beginner compound exercise performed with machine, following a horizontal push movement pattern. It primarily targets the Anterior Deltoid, Pectoralis Major (Sternal), Triceps (Long Head), with secondary engagement of the Pectoralis Major (Clavicular), Triceps (Lateral Head), Triceps (Medial Head). This is a bilateral pushing movement, meaning both sides work together to generate force.

Muscles Worked
The Anterior Deltoid, Pectoralis Major (Sternal), and Triceps (Long Head) are the primary movers, collectively driving the movement and absorbing the greatest share of the load. The Pectoralis Major (Clavicular), Triceps (Lateral Head), and Triceps (Medial Head) act as secondary movers, assisting the primary muscles and contributing meaningfully to the overall output. The Pectoralis Minor, Serratus Anterior act as stabilizers, maintaining joint position and postural alignment throughout the movement.
Primary Muscles
- Primary Muscle Anterior Deltoid (shoulders)
- Primary Muscle Pectoralis Major (Sternal) (chest)
- Primary Muscle Triceps (Long Head) (triceps)
Secondary Muscles
- Secondary Muscle Pectoralis Major (Clavicular) (chest)
- Secondary Muscle Triceps (Lateral Head) (triceps)
- Secondary Muscle Triceps (Medial Head) (triceps)
Stabilizer Muscles
- Stabilizer Muscle Pectoralis Minor (chest)
- Stabilizer Muscle Serratus Anterior (chest)
How to Perform
Preparation
- Adjust machine seat and pads to fit body.
- Sit or position body in machine.
Execution
- Press weight forward and away from chest until arms are extended.
- Return to starting position under control.
- Repeat.
Comments
- Maintain control throughout movement to fully engage the Pectoralis Major (Sternal), Anterior Deltoid, Triceps (Long Head).
Tips & Common Mistakes
- Brace your core and keep your feet flat for a stable base throughout the movement.
- Control the descent — don't let the weight drop or bounce at the bottom.
- Keep your elbows at roughly 45–75° from your torso to protect your shoulder joints.
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, Pectoralis Major (Sternal), Triceps (Long Head)) and can be substituted based on your equipment or variation preferences.
