Sometimes it might, many times it doesn't. Particularly if you're fully engaged in an intensive fitness program and have access to PTs, dieticians etc. You stated it like it was a fait accompli (ie opposite of actual sports science).Just a correction, I brought up that a dysmorphia/vanity about ab definition could hamper physical development and it could, because it does.
It's why it's been so amusing for you to hammer on about it like I'm not speaking actual sports science at you.
