Pull-Up

The Pull-Up is a fundamental bodyweight pulling exercise that develops back strength, grip strength, and upper body power. This challenging movement is ideal for intermediate to advanced fitness enthusiasts and athletes seeking improved pulling capability and functional strength. The pull-up challenges the latissimus dorsi, rhomboids, and biceps while demanding significant core stability and scapular control.

NASM’s evidence-based approach emphasizes pull-ups as a foundational movement for upper body strength and functional performance. The pull-up improves back and grip strength, develops upper body power, enhances shoulder health, and translates to improved athletic performance and functional movement capability.

How to Perform a Pull-Up

Step 1: Setup

Hang from a pull-up bar with hands positioned slightly wider than shoulder-width apart and your arms fully extended. Allow your body to hang freely.

Step 2: Brace/Position

Engage your core and prepare for pulling movement. Depress your shoulder blades and position your body for controlled vertical pulling.

Step 3: Execute/Drive

Pull your body upward by retracting your shoulder blades and driving your elbows downward. Continue pulling until your chin clears the bar or your chest approaches the bar.

Step 4: Return/Descent

Lower your body with control to the starting hanging position. Maintain tension in the back muscles throughout the movement and avoid jerky or uncontrolled descent.

Muscles Worked

Primary Muscles:

• Latissimus Dorsi -- primary mover for shoulder extension and vertical pulling motion
• Rhomboid Major and Minor -- assist in scapular retraction and shoulder blade movement

Secondary Muscles:

• Biceps Brachii
• Middle Trapezius
• Posterior Deltoid
• Core Stabilizers

Common Mistakes

• Using excessive momentum or kipping (swinging), which reduces muscle engagement
• Pulling with arms instead of back muscles, reducing latissimus involvement
• Not achieving full range of motion, which limits back muscle activation
• Jerky or uncontrolled descent, which compromises form and increases injury risk
• Failing to maintain core stability during the movement

Pull-Up Variations

• Band Assisted Pull-Up
• Assisted Pull-Up Machine
• Inverted Push-Up

As part of NASM’s evidence-based approach to movement and strength training, the barbell deadlift reinforces proper movement mechanics essential to long-term performance and injury prevention. NASM-certified personal trainers use the Optimum Performance Training (OPT) model to integrate exercises like the barbell deadlift into individualized programs based on each client’s assessment results.
