No it's pushing with your thumbs upwards and outwards on the palate of your mouth. It can stimulate bone growth and improve the maxilla bone which leads to a wider palate and opens up the nasal cavities. It also improves jaw and facial bone aesthetics. It is basically like mewing but faster and more efficient. It is still used in conjunction with mewing because mewing provides stability and reinforces the same thing but like a supporting pillar. Palate expanders work in the same way, but you can achieve similar results with thumbpulling and don't have to pay more than 10000 dollars for and have some device in your mouth constantly
It is honestly pretty interesting and it does seem to work if you do it correctly. I will try it out and see if I can improve my breathing issues. I am already mewing for a while
