Our Top Picks

Our Top Picks

Best for Additional Specializations: American Council on Exercise

American Council on Exercise

 American Council on Exercise

Why We Chose It: American Council on Exercise (ACE) is our top choice because it offers certification programs in personal training as well as group fitness instructor, medical exercise specialist, and senior fitness specialist.

  • Accredited by NCCA

  • Grounded in research

  • Online support and learning opportunities available

  • Prepares you to train specialized populations

  • Training organized around evidence-based IFT model

  • Well-respected organization/certification

  • Can be more expensive than some other choices

One of the most recognized and respected fitness organizations in the U.S., the American Council on Exercise (ACE) certifies more than 90,000 fitness and wellness professionals each year with programs accredited by the National Commission for Certifying Agencies (NCCA). In addition to the personal training certification from ACE, you can also opt to earn specialized credentials, including group fitness instructor, medical exercise specialist, senior fitness specialist, function first and pain-free movement specialist, behavior change specialist, and more.

Each of these special certifications can build upon your expertise as a certified personal trainer and prepare you to confidently train a certain population of your choosing. The behavior change specialization, for example, will teach you how to train clients who have a hard time implementing and sticking to new habits. The skills you’d learn in that program would be helpful to people who, for instance, have struggled with yo-yo dieting for years. 

It’s best to get a personal training certification before embarking on a specialization program—that’s the minimum qualification most gyms and fitness studios look for in a new trainer. The ACE personal training certification, like its specialist programs, are grounded in scientific research and functional movement training. You don’t necessarily need to be ACE-certified to do the ACE specialist programs, but it would definitely help, as the ACE specializations also utilize the integrated fitness training (IFT) model that’s central to the ACE personal trainer certification.

Best for Guided Study: National Academy of Sports Medicine

National Academy of Sports Medicine

 National Academy of Sports Medicine

Why We Chose It: National Academy of Sports Medicine (NASM) stands out because of its extensive food database and barcode scanning abilities.

  • Accredited by NCCA

  • Coursework organized around easy-to-understand pillars

  • Evidence-based curriculum

NASM chose these pillars based on longstanding scientific evidence.

For this certification, you can choose from self-study, premium self-study, guided study, or all-inclusive, but the guided study option is the most popular for good reason. This program is great for learners who need extra support and access to a mentor. With the all-inclusive option, you get a guaranteed “gymternship,” where NASM places you at a gym for 80 hours of hands-on, practical experience with personal training clients. This is a bonus that most other certifying agencies don’t offer.

The NASM program is accredited by the NCCA and is known for its evidence-based training model. The program prices range from $46 per month to $135 per month for 11 months, depending on which study option you choose. 

Best for a Deep Science Dive: American College of Sports Medicine

American College of Sports Medicine

Why We Chose It: American College of Sports Medicine (ACSM) is an excellent choice for science-loving trainers who want academic rigor and a strong connection to scientific research and standards.

The second domain—exercise programming and implementation—makes up 45 percent of the entire certification programming. This section of learning is based on decades of scientific research conducted by ACSM and other research organizations, and it teaches you how to design an effective exercise program based on your clients’ medical history, health and fitness goals, injuries, exercise preferences, and much more.

You’ll learn a great deal about anatomy, physiology, adaptations to exercise, and other important need-to-knows about the human body and fitness training. You know it’s the real deal because other certifying agencies, including ACE, actually use some research, facts, and statistics from ACSM as part of their own certification study materials. The ACSM personal training exam costs $349 for non-ACSM members and $279 for members. You can purchase books and study materials separately.

Best for Performance-Based Training: National Strength and Conditioning Association

National Strength and Conditioning Association

 National Strength and Conditioning Association

Why We Chose It: The National Strength and Conditioning Association (NSCA) is the gold standard for performance-based training. In addition to a personal training certification, it also offers a Strength and Conditioning Specialist (CSCS) certification.

  • Best known for strength conditioning programs

  • Hands-on learning is available

  • More affordable than some other choices

The National Strength and Conditioning Association (NSCA) might be best known for its certified strength and conditioning specialist (CSCS) credential, but it also offers an NCCA-accredited personal training certification. 

Because of its emphasis on performance-based training, the NSCA personal training certification is best for people who know they want to work with athletes or performance-oriented fitness enthusiasts. For example, an NSCA certification would serve you well if you want to help student-athletes prepare for college sports or propel a recreational marathoner to their next personal record.

Best for Continuing Education Support: National Federation of Professional Trainers

National Federation of Professional Trainers

 National Federation of Professional Trainers

Why We Chose It: National Federation of Professional Trainers (NFPT) stands out for its commitment to excellence when it comes to providing both fee-based and free continuing education for certified personal trainers.

  • Accredited by NCCA

  • Free continuing education

  • Reasonably priced primary certification

  • Not as well known as other certifying agencies

All personal trainers must accumulate a certain number of continuing education credits (CECs) to maintain their certifications and stay up-to-date with industry knowledge. The number of CECs you need varies based on your certifying agency, but on average, personal trainers require 20 to 45 hours of continuing education every two years.

The tricky thing is that continuing education often costs a pretty penny. It’s expensive to attend CEC-eligible conferences, especially once you factor in the cost of transportation and accommodations. Even online CEC courses can be pricey. Enter the National Federation of Professional Trainers (NFPT), which offers a suite of completely free CEC options for NFPT-certified personal trainers. You can easily acquire at least 10 hours of continuing education from these free programs if you are certified by NFPT. 

NFPT is accredited by the NCCA and has been inducted into the National Fitness Hall of Fame, which recognizes organizations and individuals who have contributed greatly to the fitness profession. To become an NFPT trainer, choose from two study packages and take the exam within one year of purchasing your study program.

The NESTA personal training certification is the only one to stay valid for four years instead of the standard two years, but you’ll still need to complete CECs within that four-year period to maintain your credential.

Final Verdict 

The personal training certifications on this list are all recognized by the health and fitness industry. That said, some are considered more rigorous than others. The personal training certification exams from ACSM and NSCA are academically challenging and require a significant amount of studying. A credential from one of these organizations can lead to a wide range of employment and career opportunities. But if you’re looking for a certification that’s slightly less intense, but still carries national recognition, then ACE is an excellent choice. 

Overall, there are many reputable programs and organizations. When researching personal training certifications on your own, always look for the National Commission for Certifying Agencies (NCCA) seal of approval. This tells you the program and certification are accredited and nationally recognized. 

Personal Trainer Certifications vs Health Coach Certifications

Although a personal trainer certification and health coach certification both prepare you to work with people on health and fitness-related issues, the prerequisites to take the exams and where you use the certifications are very different. A personal training certification allows you to work with people individually or in small groups in a fitness setting. Personal trainers often create and supervise a training program for clients. During a training session, they also educate clients on how to exercise. This includes topics like correct form, cardiovascular and muscular fitness, sets and reps, and how to choose equipment. Personal trainers also assist with setting goals and tracking progress. 

A health coach certification allows you to mentor someone as they make lifestyle changes. In this role, a health coach provides motivation and support around topics like wellness, overall health, fitness, nutrition, and emotional wellbeing. Like a personal trainer, a health coach also works one-on-one with individuals or with groups.

Frequently Asked Questions

What Do Personal Trainers Do?

A personal trainer is someone who instructs, coaches, and assists clients in achieving fitness and health goals. Personal trainers may work in a gym, studio, or fitness center and instruct individual clients or teach group classes.

Using their fitness knowledge and skills, they demonstrate exercises, teach clients how to use fitness equipment properly, or lead group instruction. In some cases, they create personalized workout plans for clients and monitor their progress, while providing support, encouragement, and feedback. They may also give advice to clients about diet and nutrition.

How Do You Become a Certified Personal Trainer?

To become a certified personal trainer, you’ll want to find a certifying organization that’s accredited by an independent third party like the National Commission for Certifying Agencies (NCCA). If you’ve fulfilled the organization’s prerequisites, you can choose a personal training program and study package, and then you need to study and pass the exam. Once you pass the test, you can start applying for personal trainer jobs, whether at gyms, health clubs, studios, spas and resorts, wellness centers, or with individual clients.

How Much Does a Personal Trainer Charge?

The average cost of personal training is about $40 to $75 per hourly session. Prices vary significantly, depending on the trainer’s experience, level of customization, and frequency of the workouts. Most personal trainers offer discounts if you purchase sessions in packages or do small group training workouts.

Is Hiring a Personal Trainer Worth It?

If you’re just starting with an exercise program, trying to lose weight, or want better results from your fitness routine, you may benefit from working with a personal trainer. Before hiring one, consider the reasons you might want a trainer and the possible benefits.

A personal trainer can develop an individualized plan for you and provide advice, support, and training to help you reach your goals. You’ll also learn the most effective workouts for your needs and how to do them properly to avoid injury.

If you’re someone who needs some extra motivation or accountability to stay on track with an exercise program, you could benefit from working with a trainer. Assuming you’re consistent with your personal training sessions and adhere to the trainer’s advice, the investment in your fitness and overall health definitely can be worthwhile.


To make the list, the certification must come from an accredited organization or certifying body and have national recognition. They also need to have materials available online in addition to paper copies. Beyond this, we considered certifications that offer both in-person and learning and self-paced, at-home study options. Most importantly, all of the personal training certification programs are accredited by the NCCA.
