I just graduated with my doctorate in physical therapy and let me tell you....this is a certification that is growing and is held in high regards by healthcare profesionals such as athletic trainers, physical therapists, chiropractors and all high level personal trainers.
It's a 100 question online exam and you have 90 minutes; you need a 70% to pass and you have 4 attempts to take it. It was worth my $570 because this is a certification a lot of trainers don't have and it will give you that edge. It is open book, but dont let that fool you; you have to be quick and know your stuff. The study material is very good and it is evidence-based.
I recommend it; if you want to take a look at the course material send me an email at
rizvihai@gmail.com; I would be glad to send them to you for you to look at before making the decision. It is a lot of stuff. They also have video demonstrations of some very effective functional-based, multiplanar exercises. But that is only if you register for the course. I couldn't extract the videos, but I have PDF files saved for the 12 chapters. Good luck.
