Personal Trainer Certifications (Which Ones Are Worth It)
Last updated:
Personal training is unusual: there is no state license to practice in the United States, so the certification you carry is the credential that signals competence to gyms, studios, and clients. That makes choosing an accredited certification important — the ones backed by the NCCA (National Commission for Certifying Agencies) are the ones most employers trust and most insurers will cover.
Below are the personal trainer certifications worth considering, who each is for, and why it is worth the time and cost, plus how to list them on your resume so they actually help you get hired.

A recognized way to add evidence-based nutrition coaching to a training practice.
CPR and AED Certification
American Heart Association (AHA) or American Red Cross · Entry
Best for: Every working personal trainer — it is a prerequisite for most CPT exams and gym jobs.
Required by nearly all employers and certifying bodies; renew it every two years and keep the card current.
How to choose the right personal trainer certification
Start with one NCCA-accredited foundational CPT — NASM, ACE, ACSM, NSCA, ISSA, or NCSF. Any of these will satisfy most gyms and let you get insured, so the choice comes down to fit: NASM and ACE are the safest general-purpose picks, ISSA and NCSF are the budget-friendly self-paced options, and ACSM or NSCA lean more clinical and strength-focused. Check the job postings at the studios or gyms you want to work for and see which names come up most.
Once you have a foundational CPT and some experience, add a specialty that matches your niche rather than collecting more general certifications. Corrective exercise, strength and conditioning, nutrition coaching, or a population specialty such as older adults all let you serve clients other trainers cannot and charge accordingly. Do not forget the unglamorous prerequisite: a current CPR and AED certification is mandatory almost everywhere.
How to list certifications on a personal trainer resume
Put your accredited CPT near the top of your resume, in your header or a dedicated Certifications section, with the full name, the issuing body, and the year (for example, "NASM-CPT, National Academy of Sports Medicine, 2024"). Spell out the acronym at least once so both a skimming hiring manager and the applicant tracking system can match it. List your current CPR and AED certification right alongside it, since employers screen for it.
Add specialties below your primary CPT and keep them current — most certifications require continuing education units to renew, so note that your credentials are active. List in-progress certifications honestly as "in progress" with an expected date, drop anything expired, and never claim a credential you have not earned, because issuing bodies make them easy to verify.

Frequently asked questions
Which personal trainer certification is the best?
There is no single best one, but NASM and ACE are the safest, most widely recognized choices for general personal training, and both are NCCA-accredited. ACSM and NSCA are stronger if you want a clinical or strength-and-conditioning focus. The most important thing is that whatever you pick is NCCA-accredited, because that is what reputable employers and insurers look for.
Do I need a license to be a personal trainer?
No. Personal training is not a licensed profession in the United States, so there is no state license to obtain. What you need instead is a recognized certification, ideally NCCA-accredited, plus a current CPR and AED certification. The certification you hold is the main credential clients and employers can verify.
How much does a personal trainer certification cost?
It varies by provider and package. Self-paced options such as ISSA and NCSF tend to be the most affordable, while NASM, ACE, ACSM, and NSCA range higher, especially with study bundles. Budget for the exam fee, study materials, and ongoing continuing education to renew, and remember the CPR and AED certification is a separate, lower cost.
Can I get certified online?
Yes. Most major certifying bodies, including NASM, ACE, ISSA, and NCSF, offer fully online study and exams, and ISSA is built around self-paced online learning. The CPR and AED component usually requires an in-person skills check even when the coursework is online.
