What Is a Personal Training Certification?

Personal training certifications are much like any other certification you would receive from an accredited organization. Personal training certifications online are much faster paced than a degree in exercise science, and typically offer an online aspect to learning. They can be earned in addition to a degree in exercise science or can stand alone as a qualification to become a personal trainer.

Certifications give you the knowledge and accreditation to work in a fitness environment and safely train clients. Depending on the accreditation of the organization you receive your certification from, you can do several things after becoming a certified personal trainer, including:

  • Be employed by a gym or fitness center
  • Work as an independent contractor at a fitness center
  • Work as a freelance personal trainer

These three options are all options for certified personal trainers, but it is ultimately up to them to choose what path works best. Some may choose to continue their education or take adjacent career paths in the fitness industry. Let’s look at some of the advantages of using your personal training certification to take any of these paths.

Using Your Certification to Be Employed By A Fitness Center

Suppose the idea for your journey is to use your training certification to be employed by a fitness center or gym. In that case, you need to carefully choose which personal training certification you attempt to receive. Gyms typically accept only personal training certifications recognized by the NCCA or The National Commission for Certifying Agencies.

Most organizations that provide personal training certifications are recognized by the NCCA, but there are some out there that are not, so be sure to do your research when searching for an organization to obtain your certification from. Fitness centers require only the most basic education as a certified personal trainer, and fitness centers already draw in a clientele. Searching for prospective clients is not usually done by certified personal trainers employed at a fitness center.

Using Your Certification to Become an Independent Contractor

Becoming an Independent Contractor as a personal trainer will require a bit more knowledge on the business aspect of the industry but will allow you more freedom when working. Choose your personal training certification by which accredited organizations offer more entrepreneurial education, like setting your prices and finding prospective clients.

Independent contractors usually pay a fee to work out of a specific gym. They could be required to carry their liability insurance if not covered by the gym they are paying fees to. Certified personal trainers have the freedom to create their schedule and prices but must work to find and retain their client base.

Using Your Certification to Work As A Freelance Personal Trainer

Freelance personal trainers have the most freedom in the industry and need the most thorough guidance in the education department to be completely prepared. Much like those desiring to be independent contractors once they are certified, freelance personal trainers should choose a certification that focuses on the business aspect of the industry.

Freelance personal trainers should seek out the highest level of education possible and look for organizations that focus on the business aspect. Freelancers should specifically seek out organizations that include entrepreneurial practices and liability insurance coverage in their courses. Freelance trainers have complete freedom over their work and typically do in-home personal training in addition to being an independent contractor at a fitness center. Freelancers must work the hardest to find and retain their client base.

What Can You Do with A Personal Training Certification?

Aside from working as a personal trainer in a gym or independently, there are several career paths you can take after receiving a personal training certification from an accredited organization. Let’s look at some of the most common specialized career paths for certified personal trainers in the fitness industry.

Certified Personal Trainers As Corrective Exercise Specialists

Corrective Exercise Specialists teach clients how to spot muscle imbalances when performing and exercising incorrectly or inefficiently. They are there to safeguard their clients from potential forms that could cause them pain or injury. Corrective Exercise Specialists can often work with clients with mobility roadblocks, including the elderly, and must be educated further on that specific client base’s restrictions.

Certified personal trainers can use their certifications to obtain a career in the corrective exercise sector of the fitness industry. Being a corrective exercise specialist involves giving constructive feedback to help clients perform exercises correctly and enable them to recover from workouts more quickly and easily.

Certified Personal Trainers as Performance Enhancement Specialists

Certified personal trainers with accredited certifications can easily opt for a career path in the athletic industry. Performance Enhancement Specialists design effective training programs for athletes in various sports looking to improve their performance.

These training professionals will evaluate exercise techniques and execution for athletes in their specific roles. This career path could take certified personal trainers into many avenues of the industry. Athletic trainers require a degree and licensure and cannot be done with just a certification…also quite common in professional sports. Though that may require additional licensure, a certifications and a degree, this can still be an advantageous avenue to take.

Certified Personal Trainers as Nutrition Coaches

Nutrition coaches work specifically with ANY type of client to teach and coach them on the basic nutritional needs and practices for a healthy lifestyle based on each individual. Nutrition coaches teach their clients about healthy eating habits and give them the tools and knowledge to implement them in their everyday lives.

Nutrition coaches typically have a passion for nutrition or a passion for working with the weight loss community. This career path is an excellent way for a certified personal trainer to make a difference in the lives of their clients by teaching them the proper way to improve their health through nutrition.

Certified Personal Trainers as Group Fitness Instructors

One of the most common routes for certified personal trainers to take, especially those employed by gyms, is to take on the role of a group fitness instructor. Group fitness instructors lead group exercise classes like aerobics or spin. Group fitness instructors have the freedom to teach many different courses that they may have a passion for. Standard group exercise classes include:

  • Yoga
  • Aerobics
  • Stretching
  • Zumba
  • Spin Classes

Group fitness instructors typically enjoy a more energetic environment with choreographed classes. Classes consist of small intimate yoga groups or large groups in a dance or Zumba class.
