There are frequent situations when a protruding abdomen can cause an excess of air, gas, and pressure within the abdomen, resulting in a visual presentation of a stomach that sticks out, but isn’t necessarily ” belly fat”.
To expand upon this, there are two main types of this:
A “Beer Belly”
where the abdomen is pushed out as a whole unit. These are usually wide infrasternal individuals who cannot expand their ribcage, so air (being a gas) follows the path of least resistance into the abdomen and results in a poor belly breathing pattern.
A “Pooch Belly”
This situation involves an even more descended diaphragm, where the diaphragm is so descended and contracted that it leads to a hyper-inflated state in the ribcage. This causes the diapgragm to change it’s line of pull on the abdomen and suck it inward and upward.
This is not necessarily a bad thing, unless there is pain or loss of range of motion involved due to a poor breathing pattern.
Both cases are usually stuck in a degree of anterior pelvic tilt which pushes their abdomen out to some degree. Therefore, activating the hamstrings will be beneficial in both cases to allow for a more “neutral” pelvic orientation.
These individuals usually are compressed from front-to-back, needing a position where gravity can help compress them from side-to-side to allow for better expansion front-to-back. These people will feel much better in a sidelying breathing position.
These people are the inverse. They’re compressed from side-to-side and generally narrow infrasternal angled individuals. They will benefit from being in a quadruped or supine position to allow them to expand from side-to-side, as gravity acts downward to compress them front-to-back.
