Assisted chin tuck

Stand with your upper back close to a wall, feet hip\u2011width, knees soft, chest tall. Place one or two fingers on the tip of your chin to guide the motion; keep eyes level. Without tilting the head, glide your chin straight back, making a small \u201Cdouble chin.\u201D Lightly touch the back of your head to the wall at the base of the skull while keeping the neck long. Hold 3\u20135 seconds, breathe normally, and keep shoulders relaxed (no shrugging). Slowly release to the start position and repeat for controlled reps. Avoid jutting the chin forward, looking up/down, or opening the mouth during the movement.
