NASM also emphasizes the importance of continuing education for fitness professionals.

These include Corrective Exercise Specialist, Performance Enhancement Specialist, Behavior Change Specialist and Weight Loss Specialist, to name a few.

In terms of methodology, NASM is recognized for its Optimum Performance Training (OPT) model, developed by Mike Clark, DPT. This is a systematic approach to program design that includes phases for stabilization, strength and power. This methodology is designed to help trainers create effective and individualized workout and nutrition programs for their clients.

NASM itself is accredited by the National Commission for Certifying Agencies (NCCA). NCCA accreditation is an important indicator of a certification program's quality and adherence to current best practices and industry standards. This certification signifies the programs NASM provides have undergone a thorough review process and meet the criteria set by the NCCA for excellence.

NASM CPT

The NASM CPT program is designed to provide a comprehensive education for individuals aspiring to become certified personal trainers.

The CPT program offers a self-paced, online learning format that includes a mix of evidence-based text, graphics, video lectures and quizzes designed to reinforce your learning. The duration of the program can vary based on individual study habits, previous knowledge base and the chosen learning path, however, most students are able to complete the course in eight to 12 weeks. You must schedule your final exam within six months of the course start date or you will have to pay to reschedule your exam.

The difficulty of the NASM CPT program is considered moderate to challenging, with the final exam having around a 75 percent pass rate. It requires a solid understanding of exercise science, anatomy and program design. The program also includes practical application components to ensure individuals can apply theoretical knowledge to real-world scenarios.

As someone who has taken the NASM CPT program, I found the course to be very comprehensive and worthwhile. There were also a number of helpful resources included on the online learning platform, including client assessment forms and example optimal performance training (OPT) exercise programs that have proven very beneficial. In terms of the difficulty, I did find it semi-challenging. However, I had taken college courses in anatomy, physiology and human biology which were incredibly helpful in completing the course.

What Is a Certified Personal Trainer Certification?

A personal training certification is proof that an individual has successfully fulfilled all of the requirements of a personal trainer course. This certification demonstrates that an individual possesses the necessary skills and qualifications to both safely and effectively design and implement exercise programs for clients.

How to Choose the Right Certified Personal Trainer Course for You

Choosing the right CPT course involves careful consideration of various factors to ensure the program aligns with your career goals, course expectations and budget. Here are some steps you can take to guide you in making an informed decision regarding which course is right for you.

Prerequisites

Both the ISSA and NASM require a high school diploma or GED to enroll in any CPT program. Both also require a cardiopulmonary resuscitation (CPR) and an automated external defibrillator (AED) certification. You may enroll in these programs prior to having your CPR and AED certifications completed, however, you will have to have them completed before you take the final CPT exam.

Industry recognition

Both the NASM and ISSA personal trainer certifications are well respected in the industry. That said, if you are set on going down a particular career path or working at a specific gym, it would be best to consult with someone from those organizations to determine which certification they may prefer you to have. A widely recognized certified personal trainer certification is more likely to enhance your credibility as a personal trainer.

Examine the course curriculum

It’s important to review the course content and curriculum to ensure it covers the essential topics you are looking to learn. These typically include anatomy, physiology, exercise science, individual client assessments and program design. A well-rounded course will help prepare you for a wider variety of client needs.

Consider the study materials and resources

Be sure to consider the style in which you learn most effectively, then evaluate the learning platform and study materials accordingly. Consider whether you prefer learning from a textbook, video lectures or hands-on application when determining which course is right for you.

Exam format

Understand the format of the final certification exam, its difficulty level and the passing criteria. This information will help you prepare effectively and gauge your readiness for the examination. Both ISSA and NASM provide study guides and practice quizzes/tests to ensure you are prepared and ready to succeed on the final exams.

Cost

Compare the cost of the certification program you are considering with the value it provides. Aside from the actual certification, many of these programs come with additional benefits such as job guarantees, professional website development and ongoing support from other trainers.

Customer reviews

Ask other personal trainers or fitness professionals their thoughts on which personal trainer certification they would recommend. Their insights, along with online customer reviews can provide valuable guidance and insight on how to choose the right program for you.

Which Is Better: NASM or ISSA?

Both the NASM and ISSA CPT programs are top-tier certifications that will be recognized and respected in the fitness industry. Both offer a similar online learning platform, are available at a similar price point and are NCCA-accredited, so there are a lot of similarities between the two programs.

If you are looking to really differentiate between the two, here are some things to consider.

NASM is best known for evidence-based methodology that emphasizes scientific principles in program design and corrective exercise. Its proprietary Optimum Performance Training model provides a systematic approach to program design, offering personal trainers a structured framework for creating effective and individualized workout programs. The NASM CPT program is a great option for individuals who plan on working at a gym, fitness center, as part of a corporate wellness program, etc.

On the other hand, ISSA covers a broad range of topics related to personal training, offering a very comprehensive education. ISSA really stresses its fitness-for-all mindset, and provides students with information on exercise for older adults, adaptive fitness, youth, pregnancy and individuals with conditions such as diabetes, arthritis, coronary heart disease and asthma. However, it may not dive into the same depth as NASM’s course in certain areas surrounding technique and corrective exercise. ISSA also offers more support for individuals looking to start their own business or side hustle, providing students a free professional website and guidance on client acquisition, marketing and legal considerations.

NASM and ISSA FAQs

Is ISSA fully accredited?

Yes, ISSA’s CPT program is NCCA-accredited.

What is the difference between ISSA's personal trainer and fitness coach?

Earning the ISSA personal trainer certification allows you to create safe and effective workout plans for clients, conduct fitness assessments and offer guidance on overall health and fitness. Personal trainers typically work one-on-one with clients in a gym setting or other fitness environment. On the other hand, fitness coaches work with clients on a more holistic level, addressing not only exercise and nutrition concerns, but also mindset, stress management and behavior change. They help guide clients in making sustainable lifestyle modifications and improve overall well-being rather than designed workout plans or training clients in the gym.

What happens if you don’t pass ISSA?

If you don’t pass your initial ISSA exam, then don’t worry because ISSA provides you with the opportunity to resubmit an examination free of charge. This will be your second attempt at the examination and each retest beyond the second attempt will incur an administrative fee.

Is NASM recognized worldwide?

Yes, NASM certifications are recognized worldwide. In fact, the NASM website states there are over 100 countries where NASM trainers work.

How long is a NASM certification good for?

The NASM Certified Personal Trainer certification is valid for two years, at which point you will need to have earned 2.0 continuing education credits and retake the exam.

Final Thoughts

While you really can’t go wrong with either of these accredited certified personal trainer programs, we hope our article helped you decide whether ISSA or NASM may be right for you. Be sure to consider your personal circumstances, how you learn and what you are hoping to learn from the courses before making your decision. I also encourage you to consult with other personal trainers or with someone in a management position at a place you would potentially enjoy working to see which certification they would recommend before making your decision.
