With an estimated 40 to 400 trainer certification programs, it’s hard to differentiate a qualified trainer than one simply with a piece of paper stating they are “certified.”

Good trainers are able to assess your overall health and fitness level, and formulate an appropriate exercise regimen to keep you motivated and in-shape. Bad trainers may have preset exercise plans for all their clients, or keep you doing the same regimen consistently, causing a plateau in your fitness level.

Look for trainers certified in programs with accreditation, as these certification programs have more sound standards.
