TL;DR: The best fitness affiliate programs for personal trainers are the ones your clients would already buy from. Here’s how to find them, what types to look for, and some options to get you started. 

“Hey, what kind of protein powder do you use?”

If you’re a personal trainer, you’ve probably got clients coming to you for advice…

All. The. Time. 

They want to know what supplements work well, which equipment they should get, which exercises they can do at home, etc. Any health and fitness question they have, they bring to you. You’re the one who helped them smash their personal best last week. They trust your judgement. 

But if you’re giving them recommendations, you’re doing free marketing for the companies you namedrop. Why not get paid for it?

Affiliate marketing extends what you’re already doing as a coach and pays YOU in the process.

In this article, we’ll break down what fitness affiliate marketing programs look like, how to choose programs that match your client base, and the best options out there. We’ll cover everything from supplements to software (yep, including ours 😎). Let’s get into it!

What Is Affiliate Marketing for Personal Trainers?

Affiliate marketing is when a brand pays you a commission for every customer you send their way. You get a unique tracking link, share it with your audience (typically via social or email), and when someone clicks and buys, you earn a cut. Simple as that. 💰

There IS a difference between the types of commissions though. 

One-time commissions – Generally paid once per customer. For example, you get $50 for each person who buys using your link. 

Recurring commissions – Paid out monthly or yearly for as long as the customer stays subscribed. 

Recurring commissions can out-earn one-offs in time, especially if that customer subscribes for years. 👀

How to Choose a Fitness Affiliate Program

Not every fitness affiliate program is gonna make sense for your business. Here’s how to evaluate which fitness affiliate marketing programs will work for you.

1. Match the product to your client base. What are the products you find yourself recommending to YOUR clients over and over again, even without a commission? That’s your sweet spot.
2. Only promote what you’d genuinely stand behind. One sketchy recommendation can tank the trust you’ve spent years building. If you wouldn’t use it yourself or recommend it to a client, don’t promote it. 🚫
3. Prioritize recurring over one-time when possible. Recurring commissions compound over time. The higher rates on one-time payouts might look attractive, but they don’t hold a candle to commissions that pay you monthly for years. 

Oh, and this goes for ANY affiliate program you end up choosing: 

You have to disclose your affiliate relationships! This isn’t optional — the FTC requires it. A simple “this post contains affiliate links” at the top of your content can cover you. Honest disclosure also builds trust with your audience, not the other way around.

The Best Fitness Affiliate Programs for Personal Trainers

We’ve grouped these health and fitness affiliate programs by category so you can match them to your audience. Commission rates and cookie windows change, so always double-check on the program’s current info before you start promoting! 🔍

Supplements and nutrition

Supplement and nutrition affiliate programs sit naturally alongside coaching, especially if you offer nutrition support or habit coaching as part of your packages. Clients buying protein, creatine, and electrolytes monthly = recurring purchase behavior, which is gold for affiliates.

Onnit

Onnit is a wellness brand known for supplements like Alpha BRAIN. They take a holistic “total human optimization” angle with their products. It’s a solid fit for trainers whose clients are into nootropics, recovery, or functional fitness. Plus, brand recognition is strong, which means lower friction at checkout.

Pros: 

• Strong brand trust
• Wide product range
• Good marketing materials provided

Cons: 

• Only a few spots in the affiliate program, so it’s highly competitive 

Commission rate: 15% Universal, $10 Trial Signup Bounty

Cookie window: 45 days

MyProtein

MyProtein is a huge global supplement brand, with everything from protein powders and vitamins to snacks and bars. The wide product range and lower price point make it a great fit if your clients want accessible pricing or are new to supplements. 

Pros: 

• Massive product catalog
• Frequent sales (good for affiliate promo angles)

Cons: 

• Very competitive program 
• Lower cookie window

Commission rate: Standard rate is 8%; up to 15% for new programs through personal trainer (PT) program

Cookie window: 30 days

Transparent Labs

Transparent Labs emphasizes “clean ingredients” in their supplements, which means no artificial sweeteners, preservatives, or coloring. It could be a strong fit if your clients are health conscious and care about ingredient quality (think pre/post-natal or wellness-leaning audiences). 

Pros: 

• Clean-ingredient positioning resonates with wellness-focused clients 
• Higher average order value than budget brands.

Equipment

Equipment affiliate programs typically pay lower percentages, but the order values are HIGH. A single rack, treadmill, or full home gym setup can put money in your pocket from one referral. If your clients are building home gyms or kitting out garage setups, this one’s for you.

Rogue Fitness

Rogue is a gold standard in strength equipment — barbells, racks, plates, the works. If you coach lifters, CrossFit-adjacent clients, or anyone serious about strength, Rogue is probably already a brand they trust. 

Pros: 

• Lifetime cookie duration. Clients can click on your link at any time and you’ll still get credited (and paid!)
• High AOV, low return rate, trusted brand

Cons: 

• Lower commission percentage
• Some product categories excluded from commissions

Commission rate: 4% on qualifying purchases

Pros: 

• Highly recommendable for online/hybrid training (small, portable, versatile)
• Strong brand recognition

Cons: 

• Long product life means clients don’t repurchase as often

Commission rate: 5-10% for all promoted products

Cookie window: 30 days

Useful for trainers whose audience includes runners, cardio-focused clients, or general wellness folks setting up home gyms. The iFIT tie-in is worth knowing about since it adds a subscription component to certain hardware sales.

Pros: 

• Established consumer brand
• High AOV
• Subscription-tied product line (iFIT) creates upsell potential

Cookie window: 30 days

Equipment recs land harder when they’re built into a structured offer, like a home-program package that includes a kit list. AKA the perfect place to embed affiliate links!

Certification and education

Don’t sleep on this category. It’s perfect for trainers whose network includes aspiring coaches, gym staff, or career-changers. Among fitness affiliate marketing programs, certification courses have high price points and clear conversion intent (people who land on the page are usually ready to enroll).

NASM

The National Academy of Sports Medicine is one of the most recognized certs in the industry. You may have seen job postings at local gyms listing it as a hiring requirement. If your audience includes anyone who’s mentioned getting certified, picking up a specialty, or breaking into the industry, NASM is the rec to make.

Pros: 

• Industry-standard recognition
• Multiple specialty bundles to promote.

Cons: 

• Narrower audience than supplements or equipment (only relevant if your network skews toward fellow trainers / aspiring coaches)

Commission rate: Varies, but most sources say flat $25 per sale

Cookie window: 30 days 

Learn more → NASM Partnerships 

ACE Fitness

ACE is the other big-name CPT. Programs and audience overlap heavily with NASM, and ACE’s affiliate program tends to have longer cookie durations compared to other fitness certification programs. That helps a lot for certification purchases because people often research for weeks before pulling the trigger.

Pros: 

• Long cookie window (forgiving for slow-moving purchase decisions)
• Strong industry credibility

Cons: 

• Narrower audience than supplements or equipment (only relevant if your network skews toward fellow trainers / aspiring coaches) 

Commission rate: ~5-8%

Cookie window: ~30-90 days

Fitness software and apps

Fitness software and apps are the MVP of recurring commissions. One referral to a SaaS platform can pay you month after month — for years — instead of a one-time hit.

ABC Trainerize

Okay, real talk: this is the program we run, so yes, we’re biased. But the structure IS different from everything else on this list, and that’s why it’s worth a closer look. 👇

ABC Trainerize is the all-in-one coaching platform fitness pros use to deliver training, nutrition, and habit coaching through a branded app. This means the affiliate audience here isn’t your clients, it’s your peers. 

Other trainers, online coaches, gym owners, studio operators — the list goes on. If you have a network in the fitness pro space (think: people you went through cert with, your TikTok or IG followers who are also trainers), this is a natural fit.

Pros: 

• Long cookie window
• Strong industry credibility
• Recurring commission stacks up over time

Cons: 

• Audience needs to include other fitness pros (won’t convert with a client-only audience)

Commission rate: 15% recurring (on monthly/annual paid plans and add-ons)

Cookie window: 90 days

The more trainers you refer, the more you earn — and KEEP earning, for as long as each one stays subscribed. 📈

Your own success as a personal trainer can also speak for itself:

When other trainers see results like this, they want to know what tools you’re using! Referring them through your affiliate link turns those conversations into income. 💪

Digital fitness platforms

These are the on-demand workout libraries and class subscriptions your clients use between sessions with you. Recommending them as accountability tools (not session replacements) frames them as a benefit, while still protecting the value of your coaching.

Les Mills

Les Mills is the brand behind BODYPUMP, BODYCOMBAT, RPM, and a bunch of other group fitness staples. Their on-demand platform is a great rec for clients who want structured group-style workouts they can do from home. It’s super handy when life or travel pulls them away from your in-person sessions.

Pros: 

• Trusted, instructor-led programming
• Subscription-based (recurring purchase behavior).

Cons: 

• Lower commission rate

Commission rate: Exact rates vary; ~6-12.5%

Cookie window: 30 days

Learn more → Les Mills Affiliate Program 

ClassPass

ClassPass gives clients access to thousands of studios, gyms, and fitness experiences in one membership. It’s a great fit for clients who travel, like variety, or live in cities with strong boutique scenes. Recommend it as a complement to (not replacement for) their work with you.

Pros: 

• Broad appeal (works across cities and workout types) 
• Recognizable consumer brand.

Cons: 

• Could pull clients toward other coaches/studios (frame carefully)

Commission rate: Varies per program. $6 USD per order. 

Cookie window: 30 days

FAQs: Fitness Affiliate Programs for Personal Trainers

What are the best health and fitness affiliate programs for personal trainers who already have clients?

If you’ve already got a client base, the best fitness affiliate programs are the ones that match what your clients are already buying. Or, if your audience keeps asking about supplements, partner with Onnit, MyProtein, or Transparent Labs. If you have a peer network of other trainers, ABC Trainerize’s 15% recurring commission is hard to beat among health and fitness affiliate programs.

How do personal trainers choose health and fitness affiliate programs that fit their audience?

Start with what you’d recommend even without a commission. These are the brands you already know, trust, and recommend to your clients. From there, consider how often clients in your niche actually buy that type of product to see if becoming an affiliate is worth your while (some programs require minimums).

What is the difference between one-time and recurring affiliate commissions in fitness?

One-time commissions pay you a single percentage when your referral makes a purchase. Recurring commissions pay you a percentage every month or year for as long as the customer keeps paying (most SaaS and subscription products, like the ABC Trainerize affiliate program). Recurring commission is the sweet spot for long-term income — one good referral can pay you for years. 

How do I disclose affiliate links as a personal trainer?

The FTC requires clear and obvious disclosure any time you have a financial relationship with a brand you’re recommending. In practice: a quick “this post contains affiliate links” at the top of a blog, “#ad” or “paid partnership” on social posts, and a verbal “I get a small commission if you use my code” on video/podcast works. Be upfront — your audience trusts you because you’re honest, and disclosure reinforces that.
