Bird Dog
The Bird Dog is a fundamental core stability exercise performed in a quadruped position with alternating opposite arm and leg extensions, developing anti-rotation core strength and coordinated movement patterns. This accessible movement is ideal for all fitness levels and those seeking improved core stability, spinal control, and functional core strength. The bird dog challenges the core through opposite limb extension that requires stability against rotational forces.
NASM's evidence-based approach emphasizes functional core exercises for developing practical stability and movement control. The bird dog improves core stability, develops coordinated movement patterns, and translates to improved functional movement quality and injury prevention.
How to Perform the Bird Dog
Step 1: Setup
Start in a quadruped position on your hands and knees with your hands positioned directly under your shoulders and your knees under your hips.
Step 2: Brace/Position
Engage your core by drawing your navel toward your spine. Maintain a neutral spine and stable torso throughout the movement.
Step 3: Execute/Drive
Extend your right arm forward while simultaneously extending your left leg backward, creating a straight line through your arm and leg. Maintain core engagement and spinal stability throughout the extension.
Step 4: Return/Descent
Return to the starting quadruped position with control. Alternate sides with opposite arm and leg extension in continuous fashion while maintaining perfect core stability.
Muscles Worked
Primary Muscles:
- Rectus Abdominis – primary stabilizer resisting spinal extension during opposite limb extension
- Transverse Abdominis – deep stabilizer providing spinal stability against rotational forces
- Erector Spinae – assist in spinal stabilization and control
Secondary Muscles:
- Obliques
- Glutes
- Shoulder Stabilizers
Common Mistakes
- Allowing the spine to rotate or the hips to shift, indicating inadequate core stability
- Jerky or uncontrolled limb movements, which compromises core stability
- Moving too quickly without maintaining spinal control
- Extending limbs too far, which removes core tension
- Holding the breath, which reduces intra-abdominal pressure and core stability
Bird Dog 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
How does bird dog training develop core stability and anti-rotation strength?
The bird dog's opposite limb extension pattern challenges the core to maintain stability against rotational forces and prevent spinal rotation. Regular practice develops anti-rotation strength essential for functional movement and injury prevention.
What should be the movement speed for bird dogs?
Perform bird dog movements slowly and deliberately, maintaining perfect core control and spinal stability throughout. Quality movement and core engagement are paramount; speed is secondary.
How many repetitions should be performed for bird dogs?
Perform 3 sets of 10-15 repetitions per side (20-30 total alternating movements), focusing on core stability and movement quality. Adjust volume based on fitness level and training phase.
