I have never heard of this cert. But there are so many out there. Do you already have their cert? I would contact them directly. Or are you trying to get information on this cert before taking it?
If you haven’t taken their program, I recommend ACSM, ACE, NASM, or NSCA. All are very well known and easy to contact. ACSM pretty much is the source for all the textbooks and materials used by everyone else.
