Do jawline exercises actually work? For building muscle, yes, as long as there’s resistance: hard chewing, resisted jaw opening and chin tucks against resistance all load real muscles. For a visibly sharper face, the evidence is thinner. Titans Jaw’s honest list has 7 jawline exercises that build real muscle (and 3 that don’t).
A quick disclosure first. We sell mastic gum, so we have a stake in this topic. Still, we’d rather be straight with you than oversell, so a few caveats below don’t help our sales.

Jawline Exercises: What They Can and Can’t Change
Start with what’s under your chin. The muscles that close your jaw, the masseter and temporalis, sit at the angle and the temple. The ones that open it sit under your chin. Neck muscles hold your head over your spine. Exercise can make all of these stronger, and some of them thicker. However, it can’t change your bone, and it can’t choose where your body loses fat.
The research backs the first part, but it warns about the second. In a 6-week trial of stroke patients, a resisted jaw-opening exercise increased the thickness of the muscles under the chin, measured on ultrasound. That’s real muscle growth, though in people doing swallowing rehab, not gym-goers chasing a look. In a six-month randomized trial of healthy adults, chewing gum three times a day raised bite force but didn’t change masseter thickness or jaw shape. Finally, a small 20-week study of middle-aged women doing facial exercises, with no control group, found fuller cheeks, not a sharper jaw.
So what exercises define the jawline? Honestly, exercise alone mostly doesn’t. The line you see is bone shape plus a thin layer of fat and skin. Training can firm the muscle underneath, but body fat moves the look more than any drill does.
7 Jawline Exercises That Build Real Muscle (and 3 That Don’t)
Here are the best jawline exercises that actually work, meaning each one puts real load on a real muscle. Go light with all of them, because jaw and neck muscles are small and tire faster than you’d think.
| Exercise | What it loads | How to do it | How strong is the evidence |
|---|---|---|---|
| 1. Resisted jaw opening | Muscles under the chin | Fist under chin. Open slowly against light pressure and hold 5 seconds | Muscle thickness rose in a 6-week rehab trial |
| 2. Chin tuck against resistance | Under-chin muscles and deep neck flexors | Press your chin into a fist or rolled towel, hold 5 to 10 seconds | Activates the same muscles as a head lift in healthy adults |
| 3. Head lift | Under-chin and front neck muscles | Lie flat, lift only your head to look at your toes, hold 10 seconds | Long used in swallowing rehab, and tough on the neck |
| 4. Neck flexion hold | Front neck muscles | Palm on forehead, push your head into it without moving, hold 5 seconds | Ordinary resistance-training logic |
| 5. Neck extension hold | Back neck muscles | Hands behind head, push back into them, hold 5 seconds | Ordinary resistance-training logic |
| 6. Firm chewing | Masseter and temporalis | Chew a firm gum slowly, alternating sides, 10 to 15 minutes | Raises bite force, no proof of visible size change |
| 7. Tongue press | Tongue and muscles under the chin | Press your whole tongue to the roof of your mouth, hold 5 seconds | Tongue training has helped swallowing muscles in older adults |
Notice what’s missing? Nothing there promises a new face. Instead, these build muscle, which firms the area and helps how you hold your head.
The 3 That Don’t Build Anything
On the other hand, three popular moves build nothing:
- Fish-face and cheek-sucking drills for slimming. They move the cheek, not the fat. In fact, a 2021 review of studies on exercising one area to lose fat there found no effect.
- Constant clenching or grinding. It isn’t training. Instead, it just wears teeth and tires the joint.
- Mewing as a stand-alone fix. Pressing your tongue up won’t hurt you, but we know of no trial showing tongue posture reshapes adult jaw bone. Most before-and-afters come down to lighting, weight and posture, so be skeptical.
Facial Fitness Routine: A Beginner Plan That Doesn’t Overdo It
A jawline workout routine for beginners should feel almost boring, because muscles adapt to steady work, not heroic sessions.
Weeks 1 and 2. First, train three days a week, with a rest day between. Do exercises 1, 2 and 4, three holds of 5 seconds each, and stop well before it burns. Call it five minutes.
Weeks 3 and 4. Same days. Next, add the head lift and tongue press, and stretch the holds to 10 seconds.
Week 5 on. Finally, if your jaw feels normal the next morning, add 10 to 15 minutes of firm chewing on a separate day. Our own guidance is 10 to 20 minutes a session, but never more.
Use the next-morning test. Tight or tender? Then take a rest day and drop back a step. The National Institute of Dental and Craniofacial Research says clicking without pain is common and normal, but pain, stiffness or locking aren’t. It also lists cutting back on jaw clenching and gum chewing as self-care for jaw disorders, so if you’ve been diagnosed with one, ask your dentist before you start anything here.
Chin Tuck Exercise: A Small Move That’s Easy to Get Wrong
The chin tuck exercise comes in two versions, and people mix them up. The posture version is just sliding your head straight back, like making a double chin on purpose, to stack your ears over your shoulders. It’s a reset, not a strength move. By contrast, the resisted version presses your chin down into a fist or towel, and that’s the one that works the muscles under your chin.
Three mistakes show up constantly: nodding the head down instead of sliding it back, shrugging the shoulders up, and pushing as hard as possible. Instead, aim for steady, light effort that you could hold while talking. It won’t melt fat, but it’s an easy way to train the area.
Where Mastic Gum Fits in a Jawline Exercise Routine
Firm chewing is the one exercise on the list we sell gear for, so here’s our honest take. It’s an easy way to give the jaw-closing muscles something to push against, and it’s simple to stay consistent with. However, it isn’t a shortcut to a new jawline, and our research roundup explains why. For the chewing side of the routine, our guide to jawline training with mastic gum covers the technique.
If you want to try it, small tears are the gentle starting point, and the shop has the rest. Also, spit it out afterward, never swallow it. Mastic comes from a relative of the pistachio, so anyone with a tree nut allergy should check with a doctor first.
Frequently Asked Questions
1. Jawline exercises vs chewing gum: which is better?
Neither wins outright, because they train different muscles. Chewing loads the muscles that close the jaw. The exercises above reach the muscles under the chin and in the neck, which gum barely touches. In the studies we found, resisted jaw opening raised muscle thickness in rehab patients, while gum raised bite force without visible size change. For most people, a few exercises plus short, controlled chewing is a sensible mix.
2. What are the best jawline exercises?
If you only pick three, make them resisted jaw opening, chin tuck against resistance and firm chewing. Together they cover the muscles under the chin, in the neck and along the jaw. Add the neck holds once those feel easy. Skip anything that promises to melt fat from your face, because bodies don’t work that way.
3. How long until they work?
Strength shows up first, usually within a few weeks, and visible change is slower and uncertain. In the jaw-opening trial, under-chin muscle thickness increased over six weeks. In the gum trial, bite force was up by three months, but masseter thickness and jaw shape hadn’t changed by six. How sharp your jaw looks depends mostly on bone and body fat, so we can’t promise a timeline for your face. Take a photo in the same light every four weeks if you want an honest record.
4. Can exercises remove a double chin?
Not directly. Working the muscles around your chin can’t pull fat from that spot. What can change how a double chin looks is losing body fat overall, improving head posture, and factors exercise can’t touch, like genes and skin elasticity. If it bothers you, a doctor or dermatologist can explain options that do target fat under the chin.
5. Should you pair them with gum?
You can, if your jaw is healthy, but ease in. Do exercises only for the first two weeks, then add one short chewing session on a different day. If you notice aching, painful clicking or headaches, drop the gum first. Skip it entirely if you’ve been told you have a jaw disorder.
6. Are daily jawline exercises safe?
For most healthy people, light daily moves are fine, but muscles grow while they rest, so we’d keep the harder holds to three days a week. It isn’t safe for everyone, though. If you have jaw pain, locking, painful clicking, frequent headaches or a clenching habit, see a dentist before you start. A few people in the jaw-opening trial had temporary joint discomfort, so go light and stop at the first sign of pain.
7. How often should you do jawline exercises?
Three non-consecutive days a week is a good default for the resisted holds. Jaw and neck muscles need a day or two to recover from hard work. Keep chewing separate, on a non-exercise day, until your jaw proves it’s ready. Consistency over months beats any single week, because strength fades when you stop. In a four-month chewing study, the gains shrank once training ended.
8. What does a neck and jaw workout look like?
About ten minutes. Start with 30 seconds of gentle jaw opening and closing, no resistance. Then do three 5-second holds each of resisted jaw opening, chin tuck against resistance, neck flexion and neck extension, resting 20 seconds between rounds. Finish with a head lift if your neck feels fine, then a slow neck stretch on each side. Everything should feel like a 4 or 5 out of 10, never a burn.
