Chin Tuck Against the Wall

Instructions

1. Stand with your back against a flat wall, heels a few inches from the base.
2. Press your upper back and head gently against the wall, looking straight ahead.
3. Without lifting your chin, slide your head straight back to create a double chin, flattening the cervical curve.
4. Hold the retracted position for 2-3 seconds, then release; repeat for the prescribed reps or duration.
