Bird Dog
How to Do the Bird Dog With Proper Form
Start on hands and knees with hands below shoulders, knees below hips, and toes resting on the floor.
Spread the fingers, press gently into the floor, and brace the trunk so the back stays long and neutral.
Reach one arm forward while extending the opposite leg backward from the hip.
Keep the pelvis level and avoid rotating the ribs or lifting the leg higher than the back line.
Pause while reaching in opposite directions through the hand and heel.
Return the hand and knee to the floor slowly without shifting your weight abruptly.
Alternate sides or complete controlled repetitions on one side before switching.
Form Check & Technique
DO THIS (Technique Tips)
- Press the floor away with both hands
- Reach long rather than lifting high
- Keep the belt line level
- Pause before returning the limbs
- Use a slow tempo until balance is automatic
AVOID THIS (Common Mistakes)
- Rotating the pelvis toward the extended leg
- Arching the lower back to lift the leg higher
- Shrugging the reaching shoulder
- Moving too quickly to maintain balance
- Shifting the body weight heavily onto one hand
- Looking forward and extending the neck
About Bird Dog
The bird dog is a quadruped stability exercise that trains the trunk to resist movement while one arm and the opposite leg extend. Start on hands and knees, brace without rounding or sagging, then reach long through the fingertips and heel. The goal is a steady spine and level pelvis, not the highest possible leg or arm lift.
Bird Dog Muscles Worked
The bird dog challenges the spinal extensors and abdominal wall to keep the trunk stable as the limbs move.
- The gluteus maximus and hamstrings extend the hip, while the shoulder and upper-back muscles support the reaching arm.
- The exercise is defined by control of the spine and pelvis during contralateral movement.
Sets & Reps Guidance
Technique / Learning
2-3 sets of 5-8 reps per side with short reaches and perfect balance.
Strength Focus
3-4 sets of 6-10 controlled reps per side with a two-second pause.
Muscle Growth (Hypertrophy)
2-4 sets of 8-15 reps per side for trunk and hip endurance.

Why the Bird Dog Trains Core Stability
Extending the opposite arm and leg narrows the base of support and creates a rotation challenge. The trunk has to resist arching, twisting, and shifting while the limbs move independently.
Bird Dog Regression
Begin by sliding one foot back or lifting one hand at a time.
- You can also extend the arm and leg only a short distance before returning to the floor.
- These options let you learn the balance demand without compensating.
Bird Dog Progressions
Progress by adding a pause, slowing the return, or extending the reach farther while keeping the pelvis level. Light ankle or wrist loading should come only after bodyweight control is reliable.
Should the Arm and Leg Go Higher Than the Back?
Usually no.
- Reaching long at roughly the height of the trunk is enough.
- Lifting higher often creates lumbar extension or pelvic rotation instead of better glute and shoulder work.
