Jaw Clench Release
The jaw clench release is a bodyweight facial exercise targeting the masseter and temporalis muscles. It involves alternating between clenching and releasing the jaw to strengthen the muscles along the jawline.
How to do it
- Sit upright with your mouth gently closed.
- Slowly clench your teeth together firmly, engaging the masseter muscles on both sides of your jaw.
- Hold the clenched position for 3–5 seconds.
- Slowly release and allow the jaw to relax completely.
- Repeat for the desired number of repetitions.
Form cues
- sit tall with relaxed shoulders
- clench teeth gently but firmly
- feel tension in the jaw muscles
- hold the squeeze steadily
- release slowly to full relaxation
Breathing: Inhale deeply before the clench, hold your breath gently during the squeeze, and exhale slowly as you release.
Common mistakes
- clenching too hard, which may cause tooth discomfort
- holding your breath, which adds unnecessary strain
- tensing the shoulders, which limits the focus on the jaw
- rushing the release, which prevents muscle relaxation
Muscles worked

Should my teeth hurt during this?
No. You should feel muscle engagement, not tooth pain. If you feel pain, reduce the intensity of your clench immediately.
How often should I do this?
Start with once a day to see how your jaw responds. Consistency is more important than high volume.
Can I do this while standing?
Yes, sitting is just recommended to help you keep your neck and shoulders relaxed.
