Greetings TGW.

I'm back. No one remembers me, but I used to be a more regular member back in the initial varbrah MSE era. Mewing took a back seat from other things in my life, and tbh I think its healthy. Obsessing too much about these things are not incredibly productive. Luckily, I am well aware of the fundamentals and have constantly been keeping oral posture as a part of my subconscious for the past 2 years.

I've just begun to look back into some of this stuff and decided to pick up where I left off. This was a profound post I left on

/community/community/main-forum/new-theory-about-maxilla-rotation/

I don't necessarily agree with the "jawning" method, but I think the poster is onto something. One thing ive realized from all these years of mewing is that we place way too much emphasis on just the tongue, and even to a lesser extent, the lips. We believe that the tongue is the driver of change, applying small force upwards to the maxilla driving it upwards and expanding it. However, this just doesnt seem right to me. In my position, as someone who actually has a case of CFD (some of you really don't and just have body dysmorphia), my palate is incredibly vaulted high and there is absolutely no way I could really hold my back third on the palate throughout the day. And even if I could... that doesn't really make sense for my case, because the maxilla is already heavily rotated forward. What I need is the FRONT portion of the maxilla raised. But I don't think that just pushing with the tongue makes sense. 

From experience, the only possible way that change is possible is through RELAXED changes. In other words, hard mewing cant work because its just straight up too hard. Youre not going to be able to maintain a hard mew subconsciously and throughout sleep. It's too much of an active process. You need to focus on posture. It needs to be EASY. 

What I've realized is that body and head posture seem to be the keys here. And I mean THE keys. Not a nice addition. But MORE important than the tongue and lips. These things are actually far more common knowledge than mewing. Everyone has been told to stand up with their chest out, shoulders back. And when you think about it, how many good looking people have you seen that are heavy slouchers? 

By pulling your head up by the occipital bone, you lengthen and straighten the spice and create a slight chin tuck. Anecdotally, this fixes some things for me. For one, my neck has always been very thin and I have much larger sternocleidomastoid muscles on my neck. When I fix my posture, over time it leads to hypotrophy of these muscles and a much more balanced look. It also makes the back of neck look much straighter with much less of a "jutted out back of head look" ( to understand what I mean, think of your stereotypically alien that has a large back head, or that Wojak meme character). Beyond that, fixing my head in this way lowers the larynx naturally, which has the effect, as referenced in the linked post above, of theoretically contracting the palatoglossus muscles which will exert natural downwards force on the back portion of the maxilla, causing CCW rotation. Also, when eating in this way, swallowing with the back portion of the tongue, and resting the whole tongue on the roof of the mouth becomes incredibly easy and relaxing. In fact it feels more natural than not having the tongue resting on the roof of the mouth. However, I do no think this is good because the tongue is helping with forces. It may help a tiny bit, but I think that its more of a byproduct of just having correct head and body posture. Theres also the idea that when you are completely straight in posture, it will reduce any lateral asymmetries in the face because everything will be focuses straight upwards instead of having the opportunity to sway to either the right or the left. 

Before I rant too long on this idea, which everyone is already on board with, I come to the question at hand. I work from home and sit a majority of my day at a desk, and I would like to constantly be sitting with correct posture discussed above. It makes sense when standing. However, I can't seem to find a good balance when sitting. Does anyone have any tips or references on how I should be sitting for correct posture? Maybe sitting in more crosslegged meditation/ yoga poses? I'm not sure but any advice would be great. Thanks.
