Yeah, but don't be a half assed trainer. Really get a grasp on physiology, movement, Anatomy, energy systems of the body.
You aren't going to just come out and make a ton of money doing it. You have to really love it.
Don't be one of these super jacked Instagram body building nikkas or big butt body building thots that doesn't know shyt about periodization, micro/macro cycling, mobility, functional movement training.
Be a good trainer, get a Very GOOD cert, and keep studying the craft.
I've been certified and updating my certs for the past 6 year even though it is only a hobby for me.
