I’ve been the Personal Training Director at 7 LA Fitness here in Texas over the last 2 years. Through my experience as an employer of Personal Trainers i’ve come to realize there are many ways to get certified as a Personal Trainer.
Number one would be to check https://www.ideafit.com/fitness-certifications.
But another and sometimes cheaper route would be to visit your local health club and ask if there having any certification bootcamps soon. I only know about the bootcamps we do at LA Fitness, but you can get a great discount by doing it that way! GlobalFitEDU is the one that hosts ours. You can visit their website at www.globalfitedu.com!
I sincerely hope this helps!
