Bird Dog with Knee-to-Elbow Crunch
Begin on all fours with hands under shoulders and knees under hips; extend opposite arm and leg straight out into a bird dog, hold briefly, then draw the elbow and knee together under the torso for a crunch, alternating sides halfway.
Key points
- Maintain a level pelvis and neutral spine without arching or sagging the lower back
- Exhale on extension and inhale as the knee and elbow crunch together under the chest
- Engage deep core stabilizers to resist rotational wobbling during transitions
Common mistakes
Over-extending the rear leg into hyperextension or allowing the hips to shift and tilt to the side.
