How to pick the right one

Start with where you want to work. If you want a job at a big gym chain, NASM or ACE are your safest bets. Both are accepted almost everywhere. If you want to train athletes, look at NSCA. If you want to work in a hospital or rehab setting, ACSM is a strong choice. If you want to train clients online with a flexible study schedule, ISSA is worth a look.

  • Check that the cert is NCCA-accredited. This is the gold standard.
  • Ask your target employer which certs they accept.
  • Compare the total cost including study materials and renewal fees.

Renewal costs matter too

Do not just look at the upfront price. You will pay a renewal fee every 2 to 3 years, plus the cost of CE courses. ACSM has the cheapest renewal at $45. ACE is the most expensive at $129. Over a 10-year career, renewal costs add up fast.
