Bird Dog
A quadruped reach drill that locks the spine while the limbs work, the cleanest entry to real core control.
What is the bird dog?
Bird dog is a quadruped drill: on hands and knees, you extend the opposite arm and leg until both are parallel to the floor, while keeping the pelvis and spine dead still. It's a McGill staple, used in clinics and elite weight rooms because it trains the same anti-extension and anti-rotation patterns you need to keep a heavy carry or a sled push from collapsing into the lower back.
How to do the bird dog
Common mistakes
- Hips rotating. If the pelvis tilts toward the lifted leg, the obliques aren't bracing. Slow down, smaller range.
- Lower back arching. A sagging spine kills the drill. Squeeze the glute and tuck the ribs before each rep.
- Rushing through reps. Speed turns this into a flapping drill. Two seconds out, two seconds back.
- Lifting the leg too high. Past parallel forces hyperextension. Stop when the leg matches the line of the back.
Variations & progressions
Arm-only or leg-only
Move one limb at a time until the brace stays clean. Add the opposite limb only when the pelvis stops moving.
Bird dog row
Anchor a band under your hand and row at the top of each rep. Anti-rotation gets brutal fast.
Dead bug
Flip onto your back, same pattern, opposite arm and leg. Lower spinal demand, similar brace skill.
How to program it
Three protocols by goal. Pick one per cycle and aim for progression on load or distance.
| Goal | Sets × Distance | Load | Rest |
|---|---|---|---|
| Movement skill | 3 × 6 reps / side | Bodyweight | 30 s |
| Core endurance | 3 × 10 reps with 3 s hold | Bodyweight | 45 s |
| Warm-up before lifts | 2 × 8 reps / side | Bodyweight | Minimal |
