As you may know, the jaw is made up of bones:
- the maxilla, which is the upper bone, under the nose.
- the mandible, which is the lower bone, under the ears to the chin.

The development of this frame depends on our genetic code, so some will naturally have a square jaw thanks to the angle that the mandible will cause on the side of their faces.
We cannot change it unless we use orthognathic surgery, unfortunately there are many constraining and negative effects (see the article “fitness rather than surgery”).

That said, our jaw is also made up of muscles, the masseters, which have a development potential similar to any other muscle in our body and we will focus on these to achieve our goal of “having a square jaw”.

As with a standard fitness exercise aimed at developing a specific muscle, we need a tool to properly recruit the muscles of our jaw, and target the masseters that are used during chewing.

Forget the pseudo exercises without any equipment consisting in contracting the muscles of your face without resistance.
The masseter muscles of the jaw need “strength” or “strength endurance” work to be really developed!
The masseters are already very powerful muscles.

With JawDesign 2021 you will be able to train them and have real results, make the masseters bigger which will rebalance and develop your jaw, thus creating this angle of face and profile, giving you a manly look and a more harmonious face.

Coaching :

If you use JawDesign 2020, the training time should not exceed 20 minutes per day, beyond that it will become uncomfortable for your teeth or gums.

If you use JawDesign 2021, there is no training time limit, the results are significant from 10 minutes a day, 5 days a week, after a month.

Start with isometric work:

Keep the jaw contracted with JawDesign for 1min .
This will stimulate the masseters and improve the synaptic connection with them.

Then a work in plyometrics:

Chew at normal pace on a reduced amplitude, perform 20 to 30 repetitions (adapt the number of repetitions according to your possibilities).

Take 30 seconds to 1 minute of rest time , then repeat this workout until you reach 10 to 20 minutes.
