Bird Dog
The bird dog builds anti-rotation and anti-extension core stability while training hip extension and shoulder flexion in a coordinated pattern. It is a staple of spinal rehabilitation programs and an excellent warm-up drill for any training session.
Setup
- Start on all fours (quadruped) with hands under shoulders and knees under hips. Maintain a neutral spine — flat back, no sagging or rounding.
- Brace your core as if someone were about to tap your stomach.
- Slowly extend your right arm straight forward and your left leg straight back simultaneously. Reach long through your fingertips and heel.
- Hold the extended position for 2-3 seconds, keeping your hips level and your spine neutral. Return to the starting position with control. Repeat on the other side.
Coaching Cues
What to feel:
- Your core and glutes working to prevent your hips from rotating or tilting
- A long, straight line from fingertips to heel at full extension
Common mistakes:
- Hiking or rotating the hip on the extended-leg side — imagine balancing a glass of water on your lower back
- Lifting the arm or leg too high, which forces the spine into hyperextension
- Moving too quickly and relying on momentum
Tip
Place a foam roller or water bottle on your lower back. If it falls off, you are rotating or extending too much. This instant feedback makes the drill dramatically more effective.

Programming
| Parameter | Recommendation |
|---|---|
| Reps | 8-12 per side |
| Sets | 2-3 |
| Hold time | 2-3 seconds at full extension |
| Frequency | 3-5 times per week |
| When to do it | Warm-up, core circuit, back rehab |
Progressions
- Beginner: Extend only the arm or only the leg (not both at the same time).
- Intermediate: Full bird dog as described with a deliberate pause at extension.
- Advanced: Add a resistance band around the feet, draw your elbow to knee between reps (crunch variation), or perform from a bear crawl position (knees hovering).
