Bird Dog
Quadruped opposite arm-and-leg reach that trains trunk stability and hip extension control.
Overview
Bird Dog is a quadruped stability drill on Flexor. From all fours, extend one arm forward and the opposite leg back until they form a long line parallel to the floor, then return and alternate sides.
What Bird Dog targets
You'll feel the core, hips, and lower back working to prevent rotation as the limbs reach. The latissimus dorsi assists on the reaching arm side.
Why add Bird Dog to your routine
Bird dog is a foundational anti-rotation exercise that supports safer lifting, running, and daily reaching patterns.
- Low-load stability work suitable for most backs.
- Alternating sides builds balanced control.
- Floor-based with no equipment.
Who it's for
Beginners learning core stability and anyone rebuilding trunk control after time off.
When to do it
Use in warm-ups, rehab-style sessions, or core blocks. Alternate for 30–45 seconds.
From all fours, brace the midsection and extend one arm forward while the opposite leg reaches straight back. Hold the long line parallel to the floor, breathe steadily, and alternate sides.
Setup cue
Start on all fours with shoulders stacked over wrists and hips over knees. Gently brace your midsection, then extend one arm forward while the opposite leg reaches straight back.
Practice notes
In Flexor, Bird Dog is typically prescribed as about 1 min per round, 1 rep, and 1 set. Adjust the dosage to what feels sustainable, breathe steadily, and ease off if anything feels sharp or unsafe.
Guidance
How to perform, tips, mistakes, safety notes, and benefits for Bird Dog.
Follow these cues in order. Move with control and stay in a comfortable range.
- Start on all fours with shoulders stacked over wrists and hips over knees.
- Gently brace your midsection, then extend one arm forward while the opposite leg reaches straight back—keep it smooth.
- Hold the long line parallel to the floor and breathe steadily before returning to tabletop.
- Alternate sides with the same calm control—keep it smooth.
Cues that help the movement stay smoother and more controlled.
- Move with control and keep breathing steadily.
- Maintain stable posture; avoid compensating with other joints.
- Maintain your hips level by pressing the supporting hand and knee firmly into the floor.
Patterns to watch for so the shape stays clearer.
- Rotating the hips open as the leg extends instead of keeping them level.
- Arching the lower back to lift the leg higher.
- Rushing reps without holding the long line briefly.
Keep things comfortable and stop if something feels wrong.
- If you have a history of spinal/neck injury, disc issues, or recent surgery, consult a clinician before progressing range or intensity.
- Stop if you feel sharp pain, numbness, tingling, dizziness, or symptoms that radiate.
- Stay within a comfortable, controlled range; muscular effort or mild stretch tension should not become pain.
- Move smoothly without bouncing, jerking, or forcing the range.
Why people include this movement in their practice.
