Chin tucks are one of the most underrated things in looksmaxxing. They are free, take about five minutes a day, and — unlike most facial "exercises" — they target something with real supporting evidence: forward head posture. This is not a first-party study. We have not tracked users or measured before/after numbers of our own. What follows is the honest mechanism, a realistic timeline, and what chin tucks can and cannot do. Take a baseline with the looksmax test if you want to track your own progress.
The honest verdict
Chin tucks and related deep-neck-flexor exercises are supported for correcting forward head posture. When your head sits over your shoulders instead of jutting forward, the jawline and neck read more clearly and a postural double chin can reduce. This is a postural change, not a bony one — you are revealing the structure you already have, not building new structure. The effect is real but modest, and it depends on you actually holding the corrected posture through the day.
What forward head posture does to your face
Forward head posture (FHP) means your head sits in front of your body's center of gravity instead of directly above it. This is caused by hours of looking at screens, phones, and laptops. The average person's head protrudes 2-3 inches forward of neutral alignment.
The facial effects are real. FHP compresses the submental area (under the chin), softening the jawline and creating the appearance of a double chin even in lean people. It shortens the apparent neck length and changes the angle at which the jaw reads from the front and side, so even a well-structured jaw can look weaker. These are effects of head position, not of your bone structure.
The good news: these effects are 100% reversible because they are postural, not structural. Correcting FHP literally reverses every negative effect. The chin tuck is the primary exercise that does this.
How to do a proper chin tuck
The chin tuck is simple but frequently done incorrectly. The motion is horizontal, not vertical — you are pulling the chin straight back, not tucking it down toward your chest.
Step 1: Starting position
Stand or sit with your back straight. Look straight ahead. Your ears should be roughly above your shoulders.
Step 2: The tuck
Pull your chin straight back — imagine making a double chin on purpose. You should feel a stretch at the base of your skull and the front of your neck engaging. Keep your eyes looking straight ahead, not down.
Step 3: Hold and release
Hold the tucked position for 5 seconds. You should feel your deep neck flexors working — these are the muscles that maintain proper head position. Release and repeat.
Step 4: The routine
30 reps, 3x daily (morning, midday, evening). Total time: about 5 minutes per day. Consistency is everything — daily practice creates lasting postural change within 2-4 weeks.
Common mistake
Do not tilt your head down. The motion is purely horizontal — chin moves straight back. Tilting down is a different exercise that does not correct FHP. If you are doing it correctly, you should look like you are giving yourself an exaggerated double chin.

What changes — and why
We are not reporting numbers from a study of our own. Here is what correcting forward head posture plausibly changes, based on the mechanism — each is an effect of head position, and each reverses if you slide back into the old posture:
Apparent jawline angle
The jaw reads sharper once the head is stacked over the shoulders rather than jutting forward.
Neck length
A neutral neck looks longer than a forward, compressed one — often the most immediate visible change.
Submental (under-chin) fullness
A postural double chin softens as the submental tissue is no longer bunched forward. Fat-driven fullness needs fat loss instead.
Overall impression
The cumulative effect of the above. It is genuine but modest, and only lasts while you hold the posture.
The only way to know your own change is to compare standardized photos — same lighting, distance, and expression — before and after a few weeks of consistent practice. A single flattering angle is not evidence.
Accelerating results with a posture corrector
Chin tucks retrain the deep neck flexors, but the problem often extends to the entire upper body — rounded shoulders and a curved thoracic spine pull the head forward. A posture corrector worn 30 minutes daily retrains the shoulders and upper back simultaneously, making chin tuck results come faster and stick better.
Pairing chin tucks with a posture corrector is a reasonable, mechanism-based combination: the exercise retrains the deep neck flexors while the corrector cues the shoulders and upper back. The corrector is a training aid, not a permanent crutch — the goal is to retrain the muscles so you hold the position naturally, then stop relying on the device.

💪 Test My Jawline →Frequently asked questions
Do chin tucks actually change your face?
Yes, but the change is postural, not structural. Correcting forward head posture makes the jawline read sharper and the neck longer, and can reduce a postural double chin. Your bones do not change — you are revealing structure the old posture was hiding.
How many chin tucks should I do per day?
30 reps, 3 times per day. Hold each for 5 seconds. Start with 10 reps per set if needed and build up. Total time: about 5 minutes daily.
How long until chin tucks show results?
Immediate effect visible in the first session. Lasting postural change: 2-4 weeks. Measurable improvement in facial metrics: 1-2 weeks.
Can chin tucks fix a double chin?
They reduce the appearance of a postural double chin by pulling submental tissue tighter. If excess body fat is the cause, you also need fat loss. Chin tucks address the posture component.
