Bird Dog
Physical therapists and strength coaches agree on very little, but both prescribe the bird dog. Extending one arm and the opposite leg from all fours teaches the lower back and core to hold a neutral spine while the limbs move — the exact skill that keeps squats and deadlifts safe. It loads almost nothing, so it fits warm-ups, rehab phases, and daily practice without eating into recovery.
How to do the bird dog, step by step
- Start on all fours with hands under shoulders and knees under hips.
- Set your spine in neutral and brace your abs lightly, as if about to be nudged.
- Reach your right arm straight ahead and your left leg straight back at the same time.
- Stop when arm, torso, and leg form one line — no higher.
- Hold for two to three seconds without letting the hips rotate or the back arch.
- Return slowly to all fours and repeat on the other side, alternating with control.
Form cues that fix most reps
Imagine balancing a cup of coffee on your lower back — nothing should spill as the limbs move.
Reach long through the heel and the fingertips instead of lifting them high.
Move slowly enough that a wobble never happens; speed is the enemy here.
Common mistakes (and the fix)
Bird Dog sets and reps
Match the rep range to your goal, not the other way around. These are the standard evidence-based ranges:
| Goal | Sets × Reps | Rest |
|---|---|---|
| Strength | 3–5 × 3–6 | 2–3 min |
| Muscle growth | 3–4 × 8–12 | 60–90 sec |
| Endurance | 2–3 × 15–20 | 30–60 sec |
Bird Dog FAQ
What muscles does the bird dog work?
The spinal erectors and deep core muscles stabilize the spine while the glutes extend the hip and the shoulder muscles hold the reaching arm. The real target is coordination: keeping the trunk dead still while opposite limbs move.
How many sets and reps of bird dogs?
Do 2–3 sets of 6–10 slow reps per side, holding each rep for two to three seconds at full extension. It works well daily as part of a warm-up, since the loading is minimal.
Is the bird dog good for lower back pain?
It is one of the most commonly prescribed exercises for building lower-back stability, because it trains the trunk to stay neutral under limb movement with very low load. It is not a treatment, though — anyone with ongoing pain should get assessed rather than self-prescribing, and the movement should feel like effort, not symptoms.
