Hi! I've got a fairly elementary question regarding abdominal support. I've used the search function a bunch, and I understand the concept of tightening the stomach muscles for support. However it seems there are 2 ways to do this. One is to pull the stomach in, ala "sucking in my gut". The other way more or less incorporates the opposite action, in that I seem to be sort of pushing the stomach out. In both cases the stomach muscles are tensed but in opposite directions. So my question is which way is correct? Or is it actually some other way I haven't considered? Thanks in advance.
