Chin tuck

Sit or stand upright with shoulders relaxed and eyes looking straight ahead. Brace lightly through your midsection and keep your jaw relaxed. Without tilting your head up or down, draw your chin straight backward as if sliding your head along a track. Feel the back of your neck lengthen and the front of your neck gently engage; keep eyes level. Hold for 3\u20135 seconds while breathing normally. Slowly return to the starting position and repeat for 8\u201312 controlled reps.
