do something.

01Beginner

Mewing

Rest your tongue flat against the roof of your mouth. This foundational technique promotes proper oral posture and may help define your jawline over time.

All day|Full jaw & face
  1. 1.Close your mouth with teeth lightly together
  2. 2.Press entire tongue against the roof of your mouth
  3. 3.Breathe through your nose
  4. 4.Maintain throughout the day
02Beginner

Jaw Clench & Release

Strengthen the masseter muscles on each side of your jaw — the primary muscles responsible for jaw definition and that angular look.

5 min|Masseter muscles
  1. 1.Clench your teeth firmly for 10 seconds
  2. 2.Release and relax for 5 seconds
  3. 3.Repeat 10-15 times
  4. 4.Do 3 sets daily
03Beginner

Chin Lifts

Target the muscles under your chin to reduce double chin and create a cleaner jawline profile. Great for tightening loose skin.

3 min|Chin & neck
  1. 1.Tilt your head back to look at the ceiling
  2. 2.Push your lower lip over your upper lip
  3. 3.Hold for 10 seconds
  4. 4.Repeat 10 times
04Intermediate

Resistance Jaw Opening

Use your fist as resistance while opening your jaw. Builds strength in the muscles that frame your lower face.

5 min|Jaw & neck
  1. 1.Place your fist under your chin
  2. 2.Push up with your fist while opening your mouth
  3. 3.Hold the tension for 5 seconds
  4. 4.3 sets of 10 reps
05Beginner

Vowel Pronunciations

Exaggerate vowel mouth shapes to work a wide range of facial muscles and improve overall jaw and face tone.

3 min|Full face
  1. 1.Open your mouth wide and say "O"
  2. 2.Stretch into "E" with a wide grin
  3. 3.Exaggerate each shape fully
  4. 4.3 sets of 15 repetitions
06Intermediate

Neck Curl-Ups

Like a crunch for your neck. Targets the platysma muscle running from your jawline to your collarbone.

5 min|Neck & submental
  1. 1.Lie on your back with tongue on roof of mouth
  2. 2.Lift your chin to your chest
  3. 3.Lower slowly without touching the ground
  4. 4.3 sets of 10
02 — The Science

The honest truth about jawline training.

Let's be upfront: there's limited clinical research on jawline exercises and mewing. The medical consensus is that significant bone structure changes are unlikely in adults through exercises alone.

What CAN change: Your masseter muscles respond to resistance training just like any other muscle. Consistent jaw exercise can increase their size and definition.

What also matters: Body fat percentage is the single biggest factor in jawline visibility. A healthy diet and regular cardio are just as important as jaw-specific training.

Our approach: We share exercises and tools that target the relevant muscles, while being transparent about what's proven and what's anecdotal.

03 — FAQ

Questions, answered.

Do jawline exercises actually work?+
Jaw exercises can strengthen and grow the masseter muscles, which may create a more angular jawline appearance. However, they cannot change your underlying bone structure, especially in adults. The biggest factor in jawline visibility is body fat percentage.
How long does it take to see results?+
Most people report noticing changes in muscle tone within 4-8 weeks of consistent daily exercise. Visible changes depend heavily on your starting body fat percentage, genetics, and consistency. Dramatic changes may take 3-6 months or longer.
Is mewing scientifically proven?+
Mewing lacks robust clinical evidence. While proper tongue posture is supported by orthodontic principles, claims about reshaping adult facial bones through mewing alone are not supported by peer-reviewed research. Generally considered safe but unlikely to produce dramatic changes in adults.
Are jaw exerciser tools safe to use?+
Most silicone jaw exercisers are generally safe for healthy adults when used as directed. Overuse can lead to jaw pain, TMJ issues, or tooth damage. Start with the lowest resistance level, limit sessions to 10-15 minutes, and stop if you feel pain.
What is the best exercise for a defined jawline?+
A combination approach works best: jaw resistance exercises to build the masseter muscles, chin lifts and neck curls to tone under the chin, regular cardio to reduce overall body fat, and good posture. No single exercise is a magic bullet.
Can you get a jawline by losing weight?+
Yes — reducing body fat is actually the most effective way to reveal your jawline. As you lose fat, your face becomes leaner and underlying bone structure becomes more visible. Combine fat loss with jaw exercises for the best results.
