Core and lower back
6 Bird Dog variations, from gentlest to strongest
Also called bird dog exercise, quadruped opposite arm leg, bird-dog.
Extending an opposite arm and leg from hands and knees while the spine stays still. It is the clearest trunk-control drill in the library, and the versions differ in how much limb is moving.
Start here
The list runs from the most supported version to the most demanding. Bird-Dog: Small Range is the one to begin with. Begin with the small-range version, or lift one limb at a time. Reaching further does not make this more effective: keeping your back still while you reach is what makes it work.

Which version should I choose?
| Version | Support | Best if | Not this one if |
|---|---|---|---|
| Bird-Dog: Small Range | None | You are starting out, or your balance is unreliable | You can already hold the classic version comfortably |
| Bird-Dog: Hand on Block | One block | Your wrists complain, or you want more stability | The block makes you feel less steady, not more |
| Bird-Dog: Forearms | None | Your wrists are the limiting factor | You have shoulder pain in this position |
| Bird-Dog: Toes on Floor | None | Lifting the leg fully is too much today | It no longer challenges you |
| Bird-Dog: Classic | None | You can extend opposite arm and leg with the back quiet | Your back arches or your hips rotate |
| Bird-Dog: Knee to Elbow | None | You want more control demand | You are still working on the classic version |
Move within a range that stays comfortable. Stop if this brings on sharp pain, dizziness, or symptoms that travel down an arm or a leg, and speak to a clinician before repeating it.
