What are our bodies actually doing when we “suck in” our gut?

Question

And where does our gut go when we do that?

In: Biology

Answer 1

Your “gut” ie your intestine is very soft. So when you contract your abdominal muscles, they push your lower abdominal cavity back. As well, you may notice you breathe in when you preform this. There is connective tissue all over your upper and lower chest cavity, when you breathe the diaphragm moves some other things with it
