Double Chin Exercises for Men: What Works and What's a Myth

By JawPeak Research Team · Updated July 3, 2026 · 9 min read

Every double-chin article gives you the same six exercises. Almost none of them tell you the part that determines whether those exercises will do anything for you: what's actually causing your double chin. Here's the full picture — exercises with doses, plus the honesty about fat that most guides skip.

What actually causes a double chin

The under-chin ("submental") area is degraded by four things, and they need different fixes:

Most men have a mix — commonly fat plus posture. That's good news: both respond well, and quickly, to the plan below.

First, the honest part: the fat lever

Evidence: strong A 2021 systematic review and meta-analysis (13 studies, 1,158 participants) found essentially zero localized fat loss from exercising a target area. Fat mobilizes systemically, in a genetically set order — and for many men the under-chin is one of the last places to lean out. So:

• If you're above roughly 18–20% body fat, a moderate caloric deficit will do more for your double chin than every exercise in this article combined. Threshold: practitioner estimate
• The chin often improves late in a cut. Weeks 2–4 usually show the first change; months 2–6 finish the job. Full pacing in our results timeline.
• Daily puffiness matters too: evening sodium, alcohol, and short sleep all push fluid into the face. Evidence: moderate Fixing those is the fastest visible win available — often within days.

Any guide that leads with "10 exercises to melt chin fat" is selling the myth. Exercises are the second half of the answer, not the first.

The 6 exercises (with exact doses)

These target the suprahyoid muscles (the floor of your mouth), the platysma (the sheet muscle of the neck), and the deep neck flexors (posture). Slow tempo, no pain, daily-friendly.

1. Chin tuck — the posture fix

1. Sit or stand tall, eyes level.
2. Glide your head straight back (make a double chin on purpose) without tilting.
3. Hold 3 seconds; release slowly.
4. Dose: 10 reps, 2× per day → build to 15 reps with 10-second holds, 3× per day. Evidence: moderate (posture)

2. Suprahyoid tongue press

1. Press your entire tongue firmly into the roof of your mouth.
2. Feel the area directly under your chin engage and lift.
3. Hold 5 seconds; release.
4. Dose: 10 reps daily → build to 15 reps of 10 seconds. Evidence: moderate (muscle function); weak for aesthetics

3. Chin-to-ceiling ("kiss the sky")

1. Tilt your head back to face the ceiling.
2. Purse your lips upward until you feel a stretch under the chin and down the front of the neck.
3. Hold 5 seconds.
4. Dose: 8 reps daily → build to 10-second holds. Stop if you feel neck pain.

4. Platysma tighten

1. Pull your lower lip and mouth corners down while tensing the front of your neck — the vertical cords should stand out.
2. Hold 5 seconds; keep it gentle.
3. Dose: 8 reps daily → build to 12.

5. Lying neck curl

1. Lie on your back, knees bent, tongue on the roof of your mouth.
2. Tuck your chin and curl your head up 2–3 inches; lower slowly.
3. Dose: 3–5 reps, 2× per week → build to 2–3 sets of 10–15, up to 3× per week. Evidence: moderate

6. Resting tongue posture

1. Rest your whole tongue on the palate, lips sealed, breathe through your nose.
2. Dose: 30-second holds, 3× per day, trending toward habit. This is a posture habit with possible tone benefit — not a fat burner or bone changer (here's the evidence on that).

Lean but still have a double chin?

If you're visibly lean elsewhere and the under-chin persists, work through this list:

1. Posture audit. Film yourself at your desk from the side. If your ear sits forward of your shoulder, forward head posture is compressing your submental area — the most common lean-guy cause, and fully fixable. Evidence: moderate
2. Hyoid position and floor-of-mouth tone. A low-positioned hyoid bone is associated with a less defined submental region (and with sleep apnea). Suprahyoid training can improve support; oral myofunctional therapy research shows these muscles respond to training. Evidence: moderate for function
3. Genetic fat storage. Some men hold a submental fat pad even at low body fat. Exercises won't remove it; injectable or surgical options exist but belong with licensed professionals, not apps or blogs.
4. Skin laxity. After large weight loss or with age. Exercise has marginal power here; the platysma's structural bands are why surgeons treat this surgically.

A recessed chin or short jaw can also mimic a double chin at any weight — that's bone anatomy, and it's fixed in adults. Honest framing: exercises optimize what you have; they don't change the skeleton.

The 4-week starting plan

1. Daily (5 minutes): chin tucks + suprahyoid presses + tongue posture + one stretch (chin-to-ceiling or platysma).
2. 2–3× per week: lying neck curls.
3. All week: caloric deficit if above ~18% body fat; evening sodium and alcohol down; 7+ hours of sleep.
4. Day 28: compare photos taken with identical head position, distance, and lighting.

From there, follow the full 12-week progression in the complete jawline exercise guide.
