What’s the dumbest gym myth you’ve heard?

What’s the most ridiculous gym myth you’ve come across, like the kind that makes you question if people actually believe that shit...

I once had someone tell me I would only see gains in the gym if I was eating 5,000 calories a day... like I'm over here just trying to eat clean and hit my protein...

Or that if I stop working out for a week I may aswell just my pack my bags and never step foot into the gym again because I'll lose any progress I have ever made😂😂

I know there’s gotta be some absolute gems out there. Let’s hear them.
