Jaw Resistance Open-close
The jaw resistance open-close is a bodyweight facial exercise targeting the masseter and temporalis muscles. It uses hand resistance while opening and closing the mouth to strengthen the jaw muscles.
How to do it
- Sit upright and place your fist under your chin.
- Apply upward pressure with your fist while slowly opening your mouth against the resistance.
- Open your mouth as wide as comfortable, maintaining resistance throughout.
- Slowly close your mouth, still pressing lightly with your fist.
- Repeat for the desired number of repetitions.
Form cues
- Sit tall with shoulders relaxed
- Apply gentle upward pressure
- Move slowly through the full range
- Keep your jaw centered
- Control the closing phase
Breathing: Inhale as you slowly open your mouth and exhale as you gently close it.
Common mistakes
- Opening too fast, which reduces muscle engagement
- Pressing too hard, which can cause jaw discomfort
- Holding your breath, which creates unnecessary tension
- Moving the head instead of the jaw, which shifts the focus away from target muscles
Muscles worked
Primary: facial muscles. Secondary: masseter, temporalis.

What if I feel clicking in my jaw?
If you hear or feel clicking, reduce the range of motion and the amount of pressure applied. Stop if you feel any discomfort.
How often should I do this?
Start with 2-3 times per week to allow your jaw muscles to adapt to the new movement.
Can I use something other than my fist?
Using your hand provides the best feedback and control for resistance; it is recommended to stick with your fist for safety.
