Floor Bridge

The Floor Bridge is a fundamental glute and lower back activation exercise performed lying on your back, developing hip extension strength and gluteal activation while promoting spinal stability. This accessible movement is ideal for all fitness levels and those seeking improved glute activation, lower back health, and hip extension strength. The bridge promotes proper glute activation patterns and posterior chain engagement.

NASM's evidence-based approach emphasizes glute activation and posterior chain development for injury prevention. The floor bridge improves glute strength, activates posterior chain muscles, and supports improved hip extension capability and lower back health.

How to Perform

Step 1: Setup

Lie on your back with your knees bent and feet flat on the floor, positioned hip-width apart. Place your arms at your sides with palms facing down for support.

Step 2: Brace/Position

Engage your core and position your feet directly under your knees. Prepare for hip extension by activating your glute muscles.

Step 3: Execute/Drive

Drive through your feet to lift your hips toward the ceiling, creating a straight line from your knees through hips to shoulders. Focus on glute contraction and hip extension throughout the movement.

Step 4: Return/Descent

Lower your hips back to the ground with control. Avoid completely relaxing your glutes at the bottom; maintain tension for continuous muscular engagement throughout the set.

Muscles Worked

Primary Muscles:

• Glutes – primary mover for hip extension and bridge lifting
• Erector Spinae – stabilize the spine and support hip extension

Secondary Muscles:

• Hamstrings
• Core Stabilizers
• Adductors

Common Mistakes

• Insufficient glute activation, using hamstrings and lower back instead
• Allowing hips to sag rather than maintaining level alignment
• Jerky or uncontrolled movements, which reduces glute engagement
• Excessive lower back arching or extension
• Not achieving adequate hip height, which limits glute stimulus

Floor Bridge Variations

• Bird Dog
• Leg Press
• Goblet Squat

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.
