I am retiring in 3 years (for the second time) and want to do something different that I enjoy part time in retirement. So I thought I would get certified as a trainer and give it a shot. What do people feel is the best certification to get?
American Council on Exercise (ACE)
National Academy of Sports Medicine (NASM)
International Sports Sciences Association (ISSA)
American College of Sports Medicine (ACSM)
National Strength and Conditioning Association (NSCA)
National Federation of Professional Trainers (NFPT)
American Fitness Professionals & Associates (AFPA)
Or does it really not matter and it's just a piece of paper?
