Building a Successful Career in Fitness and Nutrition

One survey found that approximately 74 percent of Americans have concerns about their weight. Yet, only 43 percent have changed their diet in an attempt to lose their extra pounds. Another 24 percent say their dislike of exercise makes it harder to sustain a healthy body. The University of Rochester adds that physical activity and nutrition are top health issues.

You can make a career out of helping these types of people reach their health goals as a certified personal trainer and nutrition coach. To get a better idea of what a career in fitness and nutrition entails, let's break it down.

What a Certified Nutrition Coach Does

Obtaining your nutrition certification puts you in a position to assist clients in making better daily food choices. You’ll focus on helping clients make the better nutritional decisions by setting objectives related to their health goals; for example, changing their diet to include more nutrient-dense foods and fewer unhealthy ones.

A certified nutritionist also works with clients to help them overcome food-related obstacles. This generally begins with asking clients to keep a food log. This makes it easier to see where they can improve their diet. It also brings to light poor eating habits. This tells you which changes can best help them reach their health and fitness goals.

Are "Nutritionist" and "Dietitian" the Same Thing?

No. While both offer nutrition and diet advice, a dietitian often has more formal education and legal restrictions. For example, in Texas, there are no regulations for working as a nutritionist. In Minnesota, licensure is required. There are also some states in which anyone can serve as a nutritionist, but only a registered dietitian can be reimbursed by the government.

What a Personal Trainer Does

Through exercise, personal trainers assist their clients in becoming more fit and healthy. This entails using the concepts of exercise science to develop a comprehensive fitness regimen. Fitness professionals also offer a basic level of nutrition coaching. Though, their primary focus is physical activity.

A fitness instructor listens to clients' exercise goals and devises a plan to achieve them. Some also have fitness specializations. A few to consider are group fitness or corrective exercises. Though, you can obtain trainer certification in a variety of areas.

Fitness trainers also work to uncover the obstacles clients face. Except, unlike the nutrition specialist who looks at diet, these obstacles are related to exercise. Once identified, the personal trainer finds ways to overcome them, enabling clients to meet their fitness goals.

Why Become a Fitness and Nutrition Specialist?

There are several benefits to becoming both a certified personal trainer and nutrition coach.

Address a Client’s Health Holistically

The first is that you can address more of your client's needs. This is because diet and exercise work together to enhance health.

For example, if a client eats primarily chips and cookies, their body won't have the nutrition it needs to support regular physical activity. And if they exercise without eating the right foods, they may find it harder to build muscle or lose fat.

They can also take your client's wellness to the next level. For example, one study found that diet and exercise together improved patients' health outcomes. Put another way, providing fitness and nutrition advice can reduce your client's risk of disease.

When you have your certification in both nutrition and personal training, you're able to develop a complete program. This type of health coaching enables clients to improve their health by making changes in many areas at the same time.

Boost Your Earning Potential

Getting the education needed to work as a nutritionist and personal trainer also increases your earning potential. Most nutritionists make $40,000-$70,000 per year. ZipRecruiter reports that the average annual income for a nutrition coach is $43,836 per year. Salary.com, however, indicates the average annual salary for a nutrition coach is $71,869.

Fitness professionals in the personal training space earn roughly $46,480 per year, according to the Bureau of Labor Statistics (BLS). Glassdoor notes a higher average for personal trainers at $63,643 a year. And Salary.com is again on the higher end of the averages listing the average personal trainer salary at $71,349 per year.

When you have education in both, you're able to tap into each of these markets. This also enables you to market yourself in a way that nets the most results. If the fitness market is hot, promote your personal training more. If nutrition is more in demand, share your education in this field.

The Career Outlook is Excellent

Plus, the career outlook for both nutritionists and personal trainers is favorable. According to the BLS, both industries are growing at "much faster than average" rates. This makes it a great time to earn your certification in these fields.

Working as a nutrition specialist and personal trainer also enables you to work in many different settings. You could offer your services in gyms and other fitness centers. Or you might decide to build your own business.

No matter how you decide to offer your wellness services, you'll be in a good position to help clients advance their level of health.

How to Become a Certified Nutritionist and Personal Trainer

The BLS reports that a bachelor's degree is often needed when working in nutrition and dietetics. Though, keep in mind that legal requirements are more stringent when serving as a dietitian.

If your goal is to work as a nutritionist, education is still required, but a degree isn't always necessary. The same is true for personal trainers. Some have a bachelor's degree in exercise science or physical education. Others take personal training programs before seeking their certification.

How long does it take to become a certified health coach that offers services in nutrition and exercise? The answer depends on the type of education you pursue.

If you want a bachelor's degree, you can expect to spend approximately four years in school. If your education is a self-paced online program, like what the ISSA offers, you can reduce this time. In the case of the latter, each certification can be completed in as little as a few months. If you need more time, you can stretch this out to a year or more.

Do You Need to Obtain Trainer Certification?

Whether you need to be certified to work as a nutritionist and personal trainer varies by location. Each area has its own set of requirements, so it's essential to be aware of these.

Why Get Certified If You Aren't Required?

You can prove that you have the skills necessary to create a thorough fitness and nutrition plan by completing a certification program. This ultimately aids clients in reaching better health outcomes.

Once you earn your nutrition certification and personal trainer certification, it doesn't stop there. Working in fitness and nutrition also means that you'll need to take continuing education classes to keep your certification. This ensures that you stay current with the updates in the science and the industry. The amount of continuing education credits you’ll need is set by the agency issuing your original certification.

Qualities of a Sought-After Certified Nutrition Fitness Trainer

There are a few things you can do once you become a certified nutritionist and personal trainer to increase your appeal to clients.

1. Lead by example. This is what a good nutrition coach does. It's also what a good personal trainer does. You can talk about human nutrition and exercise all day, but clients want to work with someone who can "walk the walk." They want a precision nutrition and fitness program that you're willing to do too.

2. Continuous Education. Fitness and nutrition are always evolving. Stay committed to learning about the latest trends and research. Also, learn from others who are currently working in the industry. Get their insight into what works and what doesn't. Find out the mistakes they made so you don't make them yourself.

3. Empathy and Patience. Take the time to fully understand your clients’ struggles. Offering emotional support is essential to their success. Clients will face setbacks, and it is key to motivate them through the tough times.

Choosing the Best Nutrition and Personal Training Program

If you want to work in nutrition and personal training, the next step is to decide which program to attend. What should you look for when advancing your education?

The school should provide the skills you need to work in the field. Overall, both will talk about how to promote health, but you need the specifics. As a nutritionist, for example, you will need to understand precision nutrition and know how to use it. You will need to learn about muscles and their functions if the course is about fitness.

Earning your personal trainer certification and nutrition certification from the same organization isn't mandatory, but it is helpful. It’s easier to transition from one program to the next when you're familiar with how their courses work.

Using an organization that offers recertification is beneficial too. It helps ensure that continuing education credits will be valid when it's time to renew your certification.
