I'm thinking of getting some cheap certs myself just to get my feet wet. Then maybe get some apprenticeship opportunities from real good coaches out there.
I know most people would agree when I say, the letters don't mean shit (ACE, NASM, NSCA etc..) because a lot of shitty trainers in commercial gyms look like a bunch of idiots. BUT, some trainers are absolutely amazing getting results and know their shit, so every chance I get, I talk to them and pick their brains.
I also did some volunteer stuff at some gyms, and I saw the atrocity first hand. Out of 10 PTs, I'd say 2 of them are worth talking to.
