The “best” is such a loaded word when it comes to personal training certifications. The NCAA (National Commission for Certifying Agencies) is by far the most recognized and valued accreditation body out there when it comes to personal training. But there are a multitude of colleges and trade schools that provide personal training degrees, diplomas and certifications, which are often accredited by the government (more times than not by the state the school is in).
The most respected training certifications in the industry would arguably be the following:
NASM- National Academy of Sports Medicine, ACSM- American College of Sports Medicine, NSCA- National Strength and Conditioning Association
Two of the most respected personal trainer accrediting entities are the American College of Sports Medicine (ACSM) and the National Strength and Conditioning Association (NSCA). Personal trainer accrediting agencies help new personal trainers gain credible education, skills and clients. Of course, defining the best is also partially opinion based.
