How to Become an Online Fitness Coach: The Ultimate Guide

Training clients online can be a lucrative business model for any personal trainer. Instead of limiting yourself to clients in your area or at your local gym, online fitness coaches can provide services to anyone in the world. 

Online personal training is highly scalable and yields massive profits. You can create a single program that trains thousands of people simultaneously, whereas training clients in person will always have a ceiling. 

If you’re ready to break free from your current limitations as a personal trainer, this guide will teach you how to become an online fitness coach. 

Key Takeaways

  • Scalability: Online coaching removes geographical limits and allows for one-to-many training models.
  • Certification: While not legally required, a certification increases credibility and professional trust.
  • Earning Potential: Average salaries are around $61,000, but independent coaches can earn over $250,000 annually.
  • Technology: Using a dedicated mobile app is the most effective way to distribute programs and maintain client engagement.
  • Niche Focus: Success starts with choosing a specific subcategory (e.g., postpartum women or sports-specific recovery).

What Does an Online Personal Trainer Do?

The terms online personal trainer and online fitness coach are pretty broad. But it applies to anybody who provides fitness instructions, nutrition advice, or wellness education through digital mediums—like a website or mobile app.

  • Create custom workout plans
  • Record video demonstrations of exercises
  • Provide virtual coaching services
  • Host virtual training sessions
  • Build workout calendars
  • Send motivational check-ins
  • Conduct online fitness assessments
  • Make custom meal plans with nutritional guidelines
  • Remotely communicate with clients

All of these fall within the scope of online personal training. You can choose to do as many or as few of these services as you want and even go beyond this list to stand out from other trainers. 

Do You Need a Personal Trainer Certification to Become an Online Fitness Coach?

No, there are no laws requiring personal trainers to have a certification or license. This holds for all personal trainers, including those operating online. 

Some gyms may only hire personal trainers who hold a particular license. However, this potential barrier is irrelevant if you’re selling your services online.

That said, becoming a certified personal trainer definitely adds credibility to services. You can always get certified down the road if you desire, but don’t let that hold you back from starting your online personal training business today. 

How Much Money Can You Make as an Online Personal Trainer?

Source Estimated Earnings Context
ZipRecruiter $61,000 – $108,000+ Average salary for gym-based roles
ISSA Up to $125/hour Independent coaching (~$260k/year)
PTDC Study $127,613 average Trainers with 100+ clients

As you can see, there’s quite a wide range here depending on the source and how you’re looking at the data. But I think you can safely hit a minimum of six figures within the first 12-18 months.

Can Online Fitness Coaches Still Train Clients In Person?

Absolutely. The beauty of being an online fitness coach is that it allows you to be in multiple places at once. 

So you can continue working with your existing clients without it interfering with your online personal training services. 

You may ultimately decide to transition those clients to your online program or start making enough money online that you no longer have to train clients in person. 

How to Become an Online Personal Trainer in 7 Simple Steps

Now that we’ve covered the basics, let’s jump into the actual steps required to become an online personal trainer. 

Most of these steps are fairly easy, although some (like creating custom training programs) will take a bit longer. Regardless of where you stand right now, you can complete this entire process in less than 30 days for fewer than $500. 

Step 1 — Decide Who You Want to Coach Online

This is fairly straightforward, and most of you may already have this nailed down. 

One major benefit of coaching clients online is that you can really focus on your area of expertise rather than working with any client who walks in the door. 

Instead of coaching just anyone who needs to lose weight, you can get really granular here and focus on a specific subcategory of an otherwise broad and oversaturated market. 

Here are some examples so you can see what I mean:

Weight Loss

  • Men ages 50+
  • College students
  • Postpartum women

Sports Training

  • Injury recovery
  • Strength training for football players
  • Basketball endurance training

Corporate Wellness

  • Posture correction and flexibility exercises for remote employees
  • 20-minute workouts for busy parents who work full-time
  • Virtual group coaching for offices

All of the subcategories within these niches are obviously very different. 

It’s important to narrow your focus to ensure your marketing materials and training programs actually resonate with potential clients. 

You can always expand later on. But it’s much easier to start small when you’re first launching. 

Step 2 — Choose a Core Business Model

Next, you need to determine a revenue model. There are plenty of approaches you can take, but these are the most common business models for online fitness coaches:

  • One-on-One Personal Training: Personalized attention through video calls, custom training, and in-app messaging. 
  • Membership Programs: Monthly or annual subscriptions for clients to access training materials, videos, and other workout programs.
  • Hybrid Coaching: Mix of online coaching with occasional in-person sessions for local clients. 
  • Digital Products: Charge a one-time fee for clients to access specific materials, like a downloadable meal plan.
  • Group Coaching: Train multiple clients simultaneously through a live, virtual session.
  • Online Fitness Courses: Fixed fee for a specific training course that’s designed to be completed sequentially (like a 90-day weight loss challenge).
  • Premium Access Tiers: Set up multiple subscription levels, with additional perks unlocked at higher tiers to encourage clients to pay more for premium access. 

You may ultimately decide to explore multiple business models. But I highly recommend starting with just one right now. 

Master one method first, and then experiment with others later on if you wish to expand.

Step 3 — Set Up Your Online Distribution Channel

Now you need to figure out exactly how you’re going to deliver these services to clients online. There are really only two options to consider—a website or a mobile app.

Creating a custom mobile app is clearly the best path for online personal trainers.

This gives you a direct line to clients through their smartphones, which they can easily access when they’re at the gym or training from anywhere. You can’t replicate this type of experience through the mobile version of a website. 

Having your own fitness mobile app also adds a level of professionalism to your services and helps you stand out from other trainers operating online.

Best of all, it’s easier to set up and more affordable than you think. Buildfire’s fitness app builder starts at just $85 per month, and you can try it free for 30 days.
