Has anyone heard of and practiced Mewing? Basically, instead of resting your tongue at the bottom of your mouth, it should stay at the top while you do a chin tuck permanently. When you make the ‘‘ing’’ sound, pay attention to where your tongue is, that’s where it should be.
While most most people do this to get higher cheekbones and more attractive face, the other benefits are better breathing and straight head and body posture. Here’s a good video on it… https://www.youtube.com/watch?v=WphZD3Mr2RU
Anyways, the point of my post; since starting this few days ago, I noticed that I’m breathing much better for the Star Exercise and I’m reaching the end point a lot quicker [I was getting to around breath 30 when I need to stop, now it’s close to 20] and the energy is way stronger.
