The bird dog is a hands-and-knees exercise in which you reach one arm forward and the opposite leg back until both are level with your trunk, without letting the back sag or the hips twist. It trains the muscles around the spine to hold steady against rotation, and physical therapists often use it for low back pain and degenerative disc disease. This guide is general education only: a therapist who has examined you is the one to say whether it belongs in your plan and at what dose.

How does the bird dog keep the back steady while the limbs move?
When one hand and the opposite knee leave the floor, your body is balanced on two diagonal points, and gravity tries to twist and sag the spine. The muscles along the back, the obliques and the glutes have to work together to stop that, so the bird dog trains them as a team instead of one at a time.
It belongs to a small group of low-load spine exercises, along with the curl-up and the side bridge, that the Canadian spine researcher Stuart McGill popularized for back rehab and fitness. The appeal is that it loads the spine lightly while still asking for real control, which suits a back that is sore but no longer acutely painful.
Who is the bird dog usually given to?
Therapists often give it to people whose back pain flares with twisting, lifting or long days on their feet, including those told they have degenerative disc disease, a label for age-related disc changes that many people without pain also have on imaging. It also shows up in plans for SI joint pain, where controlling pelvic rotation is part of the goal.
Rotation sports are another reason. Golfers and pickleball players load the trunk with fast turns, and the bird dog is a gentle way to rebuild control before swinging again; the golf season back pain guide sets out how that fits into a return to the course in spring.
Bird dog form faults to look for in a mirror
The fault to look for first is the hip on the lifted-leg side rising or rotating toward the ceiling. If you balanced a cup of water on your low back, that is the movement that would spill it.
- Lifting the leg higher than the hip, which arches the low back.
- Letting the belly sag toward the floor as you reach.
- Reaching the arm up toward the ceiling instead of straight ahead.
- Rushing from side to side without settling at the start.
How to scale the bird dog down or up
Scale it down by moving only one limb, and scale it up by adding time, resistance or a less stable base. Keep the first version you can do with a level back.
- Easier: slide one leg back along the floor without lifting it.
- Easier: lift one arm only, then one leg only.
- Standard: opposite arm and leg together with a short hold.
- Harder: a light band looped around the foot and the opposite hand.
- Harder still: start from a push-up plank on the hands and lift opposite limbs.
What if kneeling or putting weight on my wrists hurts?
Change the surface or the hand position rather than skipping the exercise. A folded towel or thicker mat under the knees helps sore kneecaps, and resting on your fists or forearms takes the bend out of a painful wrist.
If kneeling is impossible, for example after a knee replacement or with knee arthritis, a therapist can switch you to a standing version against a wall or a lying version such as the dead bug exercise, which trains a similar kind of control from the back. To ask for a therapist, use the back pain questionnaire.
Bird dog, step by step
A mirror or a phone filming from the side shows whether the back stays level.
Get on all fours
Kneel on a mat with hands directly under the shoulders and knees directly under the hips. Let the back rest in its natural, gently curved position, neither rounded up nor sagging.
Brace lightly
Tighten the trunk about as much as you would to stay steady if someone nudged you, not as hard as you can. Keep breathing through the whole movement.
Slide the leg back first
Slide one foot back along the floor until the leg is straight, then lift it to hip height. The pelvis should stay square to the floor, not tip toward the lifted leg.
Add the opposite arm
Reach the opposite arm forward to shoulder height with the thumb pointing up. Hold for a few seconds with the back still level.
Return under control and switch
Bring the hand and knee back to the start without letting the body sway, then repeat on the other side. Hold times and repetitions are for your therapist to set.
Stop the bird dog and see someone if...
- Leg pain, pins and needles or numbness increase while you hold the position.
- You lose control of the bladder or bowel, or feel numb in the saddle area: call 911 or go to an emergency room.
- Back pain followed a fall, a car accident or a hard landing.
- A sharp, catching pain stops you mid-movement.
- You feel faint, short of breath or have chest pain during exercise.
If you think it is an emergency, call 911.
