Exercise Profile

• Type: Compound shoulder press exercise using a Smith machine

• Equipment: Smith machine, adjustable bench with back support

• Purpose: Builds deltoid muscle strength and size, focusing on the anterior and lateral heads

Target Muscle Group

• Primary: Deltoids (mainly anterior and lateral heads)

• Secondary: Triceps brachii and upper trapezius

• Stabilizers: Core muscles supported by bench backrest, minimal compared to free weights

Overview

Performed seated on an upright bench positioned within a Smith machine, this exercise restricts the bar path to a vertical line, providing added safety and controlled movement. It targets the shoulders by pressing the bar overhead from just above shoulder height, involving triceps for elbow extension. The machine’s guide rail reduces the need for balance, allowing focused muscle engagement, making it suitable for beginners and those rehabbing shoulder issues.

Instructions

1. Set a bench with upright backrest under the Smith machine bar.

2. Adjust the bar height to align roughly with the upper chest/shoulder level.

3. Sit with feet flat, back against the bench, and grip the bar with a pronated grip slightly wider than shoulder width.

4. Unrack the bar by rotating the wrists.

5. Inhale and lower the bar slowly towards the upper chest, keeping elbows under the wrists and pointed slightly forward.

6. Exhale and press the bar upward in a controlled motion to full arm extension without locking elbows.

7. Maintain a slight lean back, keeping chest up and spine neutral.

8. Repeat for the desired rep range with stable posture and control.

9. After completing the set, carefully rack the bar back onto the machine hooks.

Tips

• Keep elbows pointed forward and avoid flaring out excessively to reduce shoulder joint stress.

• Maintain core engagement and a slight arch in the lower back to preserve spine alignment.

• Use controlled tempo—lower slowly and press up firmly.

• Keep your head neutral, not jutting forward.

• Start with a lighter load to master form before progressing heavier.

• Adjust bench and bar height for comfortable range of motion without hitting your chin or nose.

Avoid How to Perform

• Don’t lower the bar too low past the collarbone to avoid impingement.

• Avoid locking out elbows harshly at the top to preserve joint health.

• Don’t lean excessively backward or forward.

• Avoid gripping bar too wide or too narrow, causing discomfort or instability.

• Don’t rush reps or use momentum; keep movements controlled.

• Do not shrug shoulders when pressing; maintain relaxed traps.

Smith Seated Shoulder Press on a Smith machine provides a safe, stable environment to effectively train the shoulders with reduced need for stabilizers, aiding both beginners and advanced lifters in muscle development and shoulder health.
