Hi, Doug.
I would get one of the more known certs such as NASM, ACSM, NSCT, ISSA....BUT what matters more is what you do with it.
As a trainer you will make the most money working for yourself not a gym or hospital, etc.
If you choose to work for yourself, then your potential client will most likely not care who you are certified by, how many muscles you can memorize, what PHA means, etc.
Your client wants to know "What's in it for me?"
What can you, as the trainer, do for them. Lose fat, get stronger. How long will it take, will it hurt
The marketing of yourself is where most trainers miss the boat.
Get a cert and then learn marketing and business.
Just my nickels worth...and Good Luck!
