Ewww! Gross! :0ha ha that is a common reaction.
This is actually very beautiful
Here is me doing ancient stomach cleansing ritual. This is known as Uddiyana-banda. In order to do this one is recommended to practice holding the breath after full exhalation first. Once you are comfortable with retaining an exhale you should breath out all oxygen then with breath held make like you are trying to breath in while keeping the throat closed so that no air can come in. This will create pressure and draw abdominal organs up into your ribcage.
This is very therapeutic and cleansing. As with all things it gets better with practice. You may only feel slight pressure at first but soon you will develop great abdominal strength and flexibility.
To your wellness
I love you all
