Modified Push-Up
The Modified Push-Up is an accessible upper body pressing exercise performed on the knees, reducing load and difficulty for beginners and those building toward full push-up capability. This foundational movement is ideal for novice exercisers, individuals recovering from injuries, and those seeking a safe entry point into pressing exercises. The modified variation provides a manageable challenge while developing chest, shoulder, and core strength progressively.
NASM's evidence-based approach emphasizes proper progression and foundational strength development before advancing to more challenging variations. The modified push-up builds pressing strength, core stability, and serves as an essential progression toward full push-up capability and upper body strength.
How to Perform Modified Push-Up
Step 1: Setup
Start in a modified plank position with knees on the ground and hands positioned slightly wider than shoulder-width apart.
Step 2: Brace/Position
Engage your core and create a straight line from your knees to your head. Keep your shoulders back and down and maintain a neutral spine.
Step 3: Execute/Drive
Lower your body toward the floor by bending your elbows, descending until your chest nearly touches the floor. Keep your elbows at approximately 45 degrees from your body.
Step 4: Return/Descent
Press your body upward by extending your elbows, returning to the starting position. Avoid locking out your elbows at the top to maintain continuous tension in the working muscles.
Muscles Worked
Primary Muscles:
- Pectoralis Major -- primary mover for horizontal adduction during push-up
- Triceps Brachii -- assists in elbow extension throughout the pressing movement
Secondary Muscles:
- Anterior Deltoid
- Pectoralis Minor
- Serratus Anterior
- Core Stabilizers
Common Mistakes
- Allowing hips to sag, which indicates core disengagement and reduces effectiveness
- Jerky movements or excessive momentum, which compromises form
- Elbows flaring too wide, which increases shoulder stress and reduces chest activation
- Not achieving adequate range of motion, which limits chest stretch and development
- Excessive forward lean, which shifts emphasis toward shoulders
Modified Push-Up Variations
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.

FAQs
When should someone progress from modified push-ups to full push-ups?
Progress to full push-ups when you can perform 12-15 modified push-ups with perfect form and without excessive fatigue. This demonstrates adequate upper body and core strength for the increased demand of full push-ups.
What is the proper body alignment during modified push-ups?
Maintain a straight line from your knees to your head, with your core engaged to prevent hip sagging. Proper alignment ensures chest and triceps remain primary movers and reduces lower back strain.
How many repetitions of modified push-ups should be performed?
Perform 3 sets of 8-15 repetitions, adjusting based on fitness level and strength. Higher rep ranges are appropriate for beginners building foundational strength toward full push-up capability.
