Ready to get started? Let’s dive in!
#1: Sell Digital Workout Programs
First, if you’ve built custom programs for your clients, you can easily repurpose them into sellable digital products. Simply upload your workouts into ABC Trainerize, package them as 4, 6, or 12-week programs, and sell them on your website or social media.
Pro Tip: Actioning on this is a great way to scale your time. You create the program once, and clients are able to purchase and complete it without needing direct support. It’s a win-win for everyone.

#2: Offer Nutrition Coaching or Meal Plans
Next, combining fitness with nutrition is one of the easiest and most effective ways to level up your revenue. And, with ABC Trainerize’s Smart Meal Planner, you can easily offer meal guidance, assign habits, and help clients track their hydration goals.
Pro tip: You don’t need to be a registered dietitian to help clients improve their relationship with food. By offering basic meal planning and healthy habit support, you can provide tremendous value.
#3: Run Online or In-Person Challenges
Now, we all know challenges are a fun way to build community, boost accountability, and bring in extra income. You can run a 30-day step challenge, a six-week strength series, or a mindfulness challenge for your current audience.
And, ABC Trainerize Groups allows you to facilitate the challenge right inside the app. Use leaderboards to track progress, offer incentives for participation, and keep your clients engaged. It’s a great way to energize your coaching community and bring in fresh leads.
#4: Sell Fitness Templates and Resources
Next, if you’re already using templates for client check-ins or progress tracking, you can sell those resources to other coaches or clients. Think: weekly habit trackers, Google Sheets logs, printable PDF planners, or digital checklists.
Pro tip: Try hosting your products on platforms like Etsy, or your own website. These small digital products are low-maintenance and have the power to help you receive passive income on repeat.
#5: Teach Live or Pre-Recorded Classes
Now, do you love the energy of teaching? Why not turn that into a recurring income stream by offering virtual classes. You can teach via Zoom or IG Live, then upload the recordings into ABC Trainerize for on-demand access.
Pro tip: Try offering drop-in passes, class packs, or even monthly subscriptions. Whether it’s yoga, mobility, HIIT, or strength training, live or pre-recorded classes are a great way to serve a wider audience.
#6: Start Affiliate Marketing
Now, you’re already recommending products to your clients—why not get paid for it? Partner with brands you love and trust to earn affiliate commission on gear, supplements, wellness tech, or even books.
It’s a relatively low maintenance way to earn extra income. Simply share links on your social channels, blog, or newsletter. Just make sure your recommendations are authentic and aligned with your values. After all, transparency builds trust.
#7: Offer Specialty Coaching
Next, specialty coaching is where passion meets premium pricing. So, whether it’s prenatal coaching, injury prevention, mobility work, or mindset mentoring, help yourself stand out among the competition by niching down.
Pro tip: Use ABC Trainerize to build tailored programs and deliver them with high-touch support. When you specialize, you become the go-to expert—and that opens the door for higher-value clients.
#8: Create Content: Podcast, YouTube, or Blog
Pro tip: if you enjoy sharing your voice, starting a podcast, YouTube channel, or blog can help you grow your authority and expand your reach.
So, use your content to educate, inspire, and build trust. Then, over time, you’ll be able to monetize through ads, sponsorships, or by directing listeners/viewers into your coaching offers. And, don’t forget that ABC Trainerize has the ability to serve as your delivery platform when those leads convert.
#9: Write an E-Book or Fitness Guide
Next, turn your most-asked client questions into a digital product. For example, think outside of the box and create an e-book like “Macros Made Easy” or a beginner-friendly strength training guide.
These guides are great lead magnets or low-ticket digital products. You can also include them in your ABC Trainerize programs as bonus resources that add value to your coaching offer.
#10: Coach the Coaches
Finally, if you’ve built a fitness business you’re proud of, chances are newer coaches would love to learn from you. So, don’t be afraid to turn your experience into a business coaching side hustle.
You can offer one-on-one mentorship, small group programs, or workshops on building a client base, growing on social media, or pricing strategies. And, with ABC Trainerize, you’re able to deliver content modules, host groups, and manage progress all in one place.
