As for mine, as well as others that I know of, we struggle with breathing during exercise as well, not just talking, and it can very in intensity throughout the day pending on the upward pressure and the state of our nervous system. Many of us also report bloating issues, constipation... more difficult to speak when seated, as our diaphragm can't descend as well due to more compression. I know this isn't a one size fits all but it's definitely a large subset.
