I read that the back should not push hard and the front should engage morr and forward for optimal development.
But months ago almost anyone propagated the importance of a intense force of the third back...
I still am struggling with this question: Should I engage more the front, the back or both equally?
My current opinion: Swallowing properly with force > Mewing. Tongue should be resting as forward and upward as possible without force(butterfly touch). Teeth shouldn't be touching.
