You already talk about the gear you use. The protein you actually drink, the shoes you actually run in, the rack you saved up for. Fitness affiliate programs pay you for the recommendations you were making anyway.
The hard part is picking which ones to join, and the percentage next to each brand will mislead you if you let it. A 5% commission on a $2,000 treadmill pays $100. A 20% commission on a $30 protein tub pays $6.
So the top fitness affiliate programs below are grouped by what they sell, because supplements, equipment, apparel, certifications and coaching apps earn in completely different ways. Each one shows the commission, the cookie window, what a typical order is worth, and who it suits.
Four of them need no application at all, which matters if you are still building your audience. If fitness is not settled yet, the best affiliate programs cover every other category.
Key Takeaways
Key Takeaways
- Commission rate is the wrong first question. Order value times rebuy rate decides your income, not the percentage
- Supplements pay 10% to 30% on small orders, but customers rebuy monthly, which makes them the best long-run category
- Equipment pays 3% to 10% on orders from $200 to $3,000, so a single sale can beat a month of supplement commissions
- Certifications are the high ticket play, with courses running $500 to $2,000 and commissions to match
- Coaching apps pay recurring commission, which is the only fitness category where one referral pays every month
- Published rates disagree constantly. Onnit is listed as both 10% and 15% depending on the source, so always verify on the program’s own page
- Approval is the real barrier. Most major programs review your traffic, which is why marketplace access matters for smaller creators
Best Health and Fitness Affiliate Programs Compared
| Program | Category | Commission | Cookie | Best for |
|---|---|---|---|---|
| Transparent Labs | Supplements | 10% | 30 days | Evidence-led supplement content |
| Onnit | Supplements | 10% to 15% reported | 30 to 45 days | Wellness and functional fitness |
| MyProtein | Supplements | Up to 8% | 30 days | International audiences |
| Naked Nutrition | Supplements | 10% | Via brandID | Clean-label protein audiences |
| Rogue Fitness | Equipment | 5% | 30 days | Strength and CrossFit |
| Horizon Fitness | Equipment | Around 8% | 30 days | Home cardio buyers |
| Diamondback Fitness | Equipment | 10% | 365 days | Long research cycles |
| Wahoo | Equipment | Up to 10% | 7 to 30 days reported | Cycling and running tech |
| Lifeline Fitness | Equipment | 5% | 30 days | Bodyweight and functional |
| Gymshark | Apparel | Around 6% | 30 days | Younger gym audiences |
| Nike | Apparel | Up to 11% | 30 days | Launch and drop content |
| THE GYM PEOPLE | Apparel | 20% | Via brandID | Women’s activewear |
| Fabletics | Apparel | Membership based | 30 days | Subscription-style content |
| ABC Trainerize | Coaching software | 15% recurring | 30 days | Trainers with peer networks |
| ISSA and NASM | Certifications | High ticket | Varies | Aspiring trainer audiences |
| WOSPORTS | Outdoor sport | Up to 50% | Via brandID | Golf, hunting and outdoor gear |
💡 Why the numbers in these lists never match:
Programs run tiers, seasonal boosts and network-specific terms. Onnit appears as 10% in some places and 15% in others, and Wahoo’s cookie is listed as both 7 and 30 days. Verify every figure, including these.
How Fitness Affiliate Commissions Actually Work
This is the part that decides your income, and almost no list covers it. Each category earns differently, and the best one depends entirely on what your audience buys.
| Category | Typical rate | Average order | Per sale | Rebuy rate |
|---|---|---|---|---|
| Supplements | 10% to 30% | $40 to $90 | $6 to $25 | Monthly, the highest in fitness |
| Fitness equipment | 3% to 10% | $200 to $3,000 | $20 to $200+ | Every few years |
| Apparel | 5% to 11% | $60 to $150 | $4 to $16 | Seasonal |
| Certifications | 20% to 50% | $500 to $2,000 | $100 to $600+ | Once, occasionally twice |
| Coaching apps | 15% to 40% recurring | $15 to $50 monthly | Paid every month | Ongoing until they cancel |
| Wearables and tech | 3% to 10% | $150 to $600 | $10 to $50 | Every two to three years |
Two conclusions follow from this table. Supplements win over a year because people rebuy every month, and one equipment sale can beat a month of supplement commissions but will not repeat.
The strongest setup runs both. Supplements for the baseline, equipment and certifications for the spikes.
Best Fitness Supplement Affiliate Programs
Supplements are where most fitness affiliate marketing programs start, because the audience buys monthly and the content writes itself. The wider mechanics are covered in the affiliate marketing guide.
1- Transparent Labs
Transparent Labs is a supplement brand built around full ingredient disclosure, which is unusual in a category where proprietary blends are the norm.
That matters for affiliates because the brand gives you something concrete to say. Among fitness supplement affiliate programs it is one of the easier ones to recommend, because you can compare a label against a competitor and let the difference make the argument.
Transparent Labs Affiliate Program Details:
- Commission: 10% on new-referral orders
- Cookie: 30 days
- Products: Pre-workout, protein, creatine, fat burners
- Approval: Application required, terms published openly
Best For: Creators whose audience wants a reason behind every recommendation rather than a discount code.
2- Onnit
Onnit is a wellness brand covering supplements, kettlebells and apparel, best known for Alpha BRAIN and its functional fitness range.
It appears on almost every list of the best health and fitness affiliate programs, though reported commission varies by source between 10% and 15%, and the cookie between 30 and 45 days. Verify current terms before building around it.
Onnit Affiliate Program Details:
- Commission: 10% to 15% depending on source and tier
- Cookie: 30 to 45 days reported
- Average order: Around $80 to $100
- Products: Supplements, kettlebells, apparel, nootropics
Best For: Wellness and functional fitness audiences, where brand recognition reduces checkout friction.
3- MyProtein
MyProtein is one of the largest sports nutrition retailers globally, with localized storefronts across Europe, Asia and North America.
Its advantage is international reach. Most fitness affiliate marketing programs are single-market, so if your audience is spread across countries a large share of them will never convert.
MyProtein Affiliate Program Details:
- Commission: Up to 8%, varying by market and product
- Cookie: 30 days
- Products: Protein, vitamins, snacks, clothing
- Strength: Localized sites in dozens of countries
Best For: Creators with international audiences who lose conversions on US-only programs.
4- Naked Nutrition
Naked Nutrition is a clean-label supplement brand whose whole positioning is short ingredient lists, often a single ingredient with nothing added.
That makes it unusually easy to recommend, because the argument is on the label rather than in the marketing. Among fitness supplement affiliate programs it is also one of the few with no approval step, and the range covers whey isolate, glutamine, pre-workout, mass gainer and beef protein.
Naked Nutrition Affiliate Program Details:
- Commission: 10%
- Products: Whey isolate, glutamine, pre-workout, mass gainer, beef protein
- Access: brandID affiliate marketplace
- Approval: None
Best For: Creators whose audience reads ingredient lists and asks what is actually in things.
5- Optimum Nutrition
Optimum Nutrition is the brand behind Gold Standard 100% Whey, which is probably the single most recognized protein powder in the world.
Recognition is the whole advantage here. Among the top fitness affiliate programs it needs the least explaining, which matters in short-form content where you have eight seconds.
Optimum Nutrition Affiliate Program Details:
- Commission: Varies by retailer and region
- Products: Whey, casein, bars, amino acids, pre-workout
- Strength: Highest brand recognition in sports nutrition
- Note: Often promoted through retailer programs rather than direct
Best For: Beginner-focused content, where a familiar name converts better than a better formula.
Best Fitness Equipment Affiliate Programs
Fitness equipment affiliate programs pay lower percentages and much larger amounts per sale, because a treadmill is a thousand-dollar decision rather than a thirty-dollar one. Amazon carries most of the same brands, and the Amazon affiliate program pays 3% on sports and outdoors.
6- Rogue Fitness
Rogue Fitness makes strength equipment, from barbells and racks to full gym fit-outs, and is the default brand in CrossFit and powerlifting circles.
The 5% rate looks thin next to other fitness equipment affiliate programs until you notice that a home rack setup routinely passes $1,500, which makes a single conversion worth more than dozens of supplement sales.
Rogue Fitness Affiliate Program Details:
- Commission: 5%
- Cookie: 30 days
- Average order: High, often $500 to $2,000+
- Products: Racks, barbells, plates, conditioning gear
Best For: Strength training and home gym content where readers are researching a large purchase.
7- Diamondback Fitness
Diamondback Fitness sells cardio equipment, and its affiliate program has the longest cookie window in this entire list at 365 days.
That length matters more than the rate here, and it is the single biggest advantage any of these fitness equipment affiliate programs offers. Buyers research for weeks or months, and a 30-day cookie expires long before many of them decide.
Diamondback Affiliate Program Details:
- Commission: 10%
- Cookie: 365 days, the longest in fitness
- Products: Exercise bikes, ellipticals, recumbents
- Why it matters: Long research cycles finally get credited
Best For: Anyone writing equipment comparison content, where the purchase decision takes months.
8- Wahoo Fitness
Wahoo makes cycling and running technology, including smart trainers, bike computers and heart rate monitors.
It sits at the intersection of fitness and tech, which is a smaller audience with unusually high buying intent and order values.
Wahoo Affiliate Program Details:
- Commission: Up to 10% on non-trainer products, around 7.5% on smart trainers
- Cookie: Reported as both 7 and 30 days, so verify
- Payout: PayPal, $100 minimum
- Average order: Around $200
Best For: Cycling, triathlon and running-tech creators.
9- Nattork
Nattork makes skating equipment, covering ice skates, adjustable roller skates and inline skates for both kids and adults.
It sits in a corner of fitness most affiliate lists ignore entirely, which is exactly why it is worth knowing about. Family and kids fitness content has very few programs aimed at it.
Nattork Affiliate Program Details:
- Commission: 15%
- Products: Ice skates, roller skates, adjustable inline skates
- Access: brandID affiliate marketplace
- Approval: None
Best For: Family fitness, kids activity and parenting creators, where mainstream gym brands do not fit.
10- Horizon Fitness
Horizon Fitness has made cardio equipment since 1999, covering treadmills, ellipticals, bikes and rowers at prices below the premium brands.
The affordability angle is the content angle. Most home cardio buyers are choosing between a $999 machine and a $3,000 one, and that comparison is a whole article on its own.
Horizon Fitness Affiliate Program Details:
- Commission: Around 8%
- Cookie: 30 days
- Average order: $700 to $2,000
- Products: Treadmills, ellipticals, bikes, rowers
Best For: Home gym and cardio content aimed at buyers on a budget rather than at the premium end.
Best Fitness Apparel Affiliate Programs
Fitness apparel affiliate programs convert well on visual platforms because the product is the content. The tradeoff is lower order values and heavy seasonality. Short-form video is where most of it happens, which the TikTok Shop affiliate route covers natively.
11- Gymshark
Gymshark is a gym apparel brand built almost entirely through influencer marketing, which means its audience is already conditioned to buy from creators.
Reported commission sits around 6%, which is modest for fitness apparel affiliate programs, but conversion rates here are unusually high because the brand does the persuading for you.
Gymshark Affiliate Program Details:
- Commission: Around 6%
- Cookie: 30 days
- Average order: Roughly $100
- Audience: Younger gym-going demographic
Best For: Creators with gym-focused audiences under 35, especially on short-form video.
12- Nike
Nike needs no introduction, and its affiliate program pays up to 11%, which is higher than most apparel brands.
Approval is the constraint. Nike sits among the highest paying fitness affiliate programs on rate, but it reviews traffic quality and content standards, so newer sites are frequently declined.
Nike Affiliate Program Details:
- Commission: Up to 11%
- Cookie: 30 days
- Approval: Application reviewed on traffic and content quality
- Best content: Launches and drops, covered quickly
Best For: Established creators whose audience follows releases rather than evergreen guides.
13- Fabletics
Fabletics sells activewear through a membership model, where customers pay a monthly fee in exchange for member pricing on outfits.
The subscription structure is the point for affiliates. Most fitness apparel affiliate programs pay once per order, while a Fabletics signup keeps paying because the customer keeps subscribing.
Fabletics Affiliate Program Details:
- Commission: Membership based, paid on signups rather than order value
- Cookie: 30 days
- Products: Women’s and men’s activewear, footwear, accessories
- Model: VIP membership with member pricing
Best For: Creators whose audience buys workout outfits regularly rather than occasionally.
14- Under Armour
Under Armour covers performance apparel, footwear and accessories, and sits between Nike’s launch culture and the cheaper gym brands.
It works best for evergreen search content and seasonal sale pages rather than drops, because the brand runs discounts far more often than Nike does.
Under Armour Affiliate Program Details:
- Commission: Typically 5% to 10%
- Cookie: 30 days
- Products: Training apparel, footwear, accessories
- Best content: Evergreen guides and sale roundups
Best For: Blog and search-led creators rather than short-form video accounts.
15- Lifeline Fitness
Lifeline Fitness makes functional training tools, best known for its original beaded jump rope and the Jungle Gym suspension trainer.
The products are cheap enough to recommend casually, which is rare in equipment. Most of the category needs a considered-purchase article; a jump rope does not.
Lifeline Fitness Affiliate Program Details:
- Commission: 5%
- Cookie: 30 days
- Products: Jump ropes, suspension trainers, resistance bands, recovery tools
- Order value: Low, which suits impulse recommendations
Best For: Bodyweight, home workout and travel fitness content where big equipment does not apply.
Women’s Fitness Affiliate Programs
Women’s fitness affiliate programs are the fastest-growing segment of this category, and the apparel brands in it convert better than the unisex ones because the fit conversation is specific.
16- THE GYM PEOPLE
THE GYM PEOPLE makes women’s activewear, covering high-waisted running shorts, workout joggers, half-zip fleece pullovers, capris and tees.
At 20% commission it pays roughly three times what Gymshark does, which makes it one of the strongest women’s fitness affiliate programs available, and it is in the brandID marketplace with no separate application.
THE GYM PEOPLE Affiliate Program Details:
- Commission: 20%, among the highest in fitness apparel
- Products: Running shorts, joggers, hoodies, capris, tees
- Access: Through the brandID affiliate marketplace
- Approval: None required
Best For: Creators making women’s workout content, hauls, fit checks or gym outfit posts.
The broader wardrobe angle is covered in the best fashion affiliate programs, which overlap heavily with activewear.
High Ticket Health and Fitness Affiliate Programs
High ticket health and fitness affiliate programs pay hundreds per conversion rather than tens. The tradeoff is that they convert far less often and need genuine authority behind the recommendation.
17- ISSA and NASM Certifications
ISSA and NASM are the two largest personal training certification bodies, and their courses run from roughly $500 to $2,000.
These are the best affiliate programs for fitness creators with real authority, because the commission is a share of a four-figure course rather than a supplement tub.
Certification Affiliate Program Details:
- Course price: $500 to $2,000 depending on the bundle
- Commission: High ticket, typically a substantial share per enrollment
- Conversion: Low volume, high value
- Audience needed: People considering fitness as a career
Best For: Trainers, coaches and creators whose audience asks how to get certified.
Comparable payouts outside fitness are collected in the best high ticket affiliate marketing programs.
Coaches with an audience often skip affiliate income entirely and go straight to selling fitness programs online, which pays the full price rather than a share of it.
18- WOSPORTS
WOSPORTS makes golf rangefinders, night vision goggles, trail cameras and spotting scopes, and it pays the highest commission of anything in this article.
Golf and outdoor sport sit just outside gym fitness, but the audience overlaps heavily and the order values are far higher. At up to 50% it beats every other program here on rate, which is rare in high ticket health and fitness affiliate programs.
WOSPORTS Affiliate Program Details:
- Commission: Up to 50% on rangefinders, 35% and 20% on other lines
- Products: Golf rangefinders, night vision, trail cameras, spotting scopes
- Access: brandID affiliate marketplace
- Approval: None
Best For: Golf, hunting and outdoor sport creators, and anyone whose fitness audience skews male and over 35.
19- ABC Trainerize
ABC Trainerize is coaching software that personal trainers use to deliver programs and track clients, and its affiliate program pays 15% recurring.
Recurring is what makes this different. One referred trainer pays you every month for as long as they stay subscribed, which no product-based program does.
ABC Trainerize Affiliate Program Details:
- Commission: 15% recurring
- Cookie: 30 days
- Payment model: Monthly for the life of the subscription
- Audience: Personal trainers and coaches
Best For: Creators with a professional peer network rather than a consumer audience.
Why Four of Those Programs Need No Application
Naked Nutrition, Nattork, THE GYM PEOPLE and WOSPORTS are marked differently above for a reason. Every other program on this list reviews your traffic before accepting you.
For a creator under a few thousand followers, that is the actual barrier. The rates are irrelevant if the approvals never come through.
brandID runs an affiliate marketplace that removes the step. You pick a brand, add its products to your page, and the links are live immediately.
| Traditional programs | brandID marketplace | |
|---|---|---|
| Approval | Per brand, traffic reviewed | None |
| Follower minimum | Often required | None |
| Applications | One per brand | One account |
| Dashboards | One per program | One |
| Payout threshold | $50 to $100 typical | No minimum |
| Payout frequency | Monthly, net 30 to 60 | Weekly |
| Catalog | What you were approved for | 5 million+ products, 2,000+ brands |
The four fitness brands above are a small sample. The catalog covers most consumer categories, and the best affiliate marketing niches show which of them pay best.
Creators keep 95% of every sale on the free plan and 100% once they subscribe to any paid plan using their own payment gateway, with plans from $9 a month.
How to Choose the Best Affiliate Programs for Fitness Content
- 1- Start from what your audience already buys. If they ask about protein, supplements convert. If they ask about home gyms, equipment does. Guessing wastes months.
- 2- Multiply rate by order value before comparing. A 5% commission on $1,500 beats a 20% commission on $40 by a factor of nine.
- 3- Check the cookie window against the decision time. Equipment buyers research for weeks, so a 30-day cookie expires before many of them decide.
- 4- Prefer recurring where it exists. Coaching software and subscription apps pay every month from one referral.
- 5- Check whether you will actually be approved. Most major programs review traffic, and a rejection costs you the time you spent planning around it.
- 6- Run two categories, not six. One supplement program for the baseline and one equipment or certification program for the spikes.
How to Promote Fitness Affiliate Links
- Show the product in use, not in a box. Fitness converts on demonstration more than on specification.
- Answer the buying question directly. Best kettlebells for a small apartment outperforms a generic brand roundup every time.
- Use your own results carefully. Genuine before-and-after content converts, and exaggerated claims lose the audience permanently.
- Put the links somewhere permanent. Stories disappear in 24 hours, so a page collecting everything you recommend earns long after the post.
- Disclose the relationship. FTC rules require it and audiences respond better to affiliates who say so plainly.
- Start before you have an audience. You can start affiliate marketing with no money, and fitness is one of the cheapest niches to test.
The platform-by-platform detail sits in how to promote affiliate links, which covers what works on each one.
Mistakes to Avoid
- Chasing the highest percentage. A 30% commission on a $20 product pays $6. Order value decides your income.
- Joining twelve programs at once. Each has its own threshold, and spreading sales across all of them means reaching none.
- Promoting supplements you have not used. This category punishes it faster than any other, because the audience compares labels.
- Ignoring the rebuy rate. Supplements pay less per sale and considerably more per customer over a year.
- Making health claims. Supplement and fitness claims are regulated, and a program will drop you for them.
- Building on one program. Rates get cut without notice, and every figure in this article could change next quarter.
Conclusion
The best fitness affiliate programs are not the ones paying the highest percentage. They are the ones selling what your audience was already going to buy, at a price point where the commission is worth the content.
Supplements give you a monthly baseline. Equipment and certifications give you the occasional large payday. Coaching software gives you recurring income if your audience happens to be other trainers.
Start with one from each of two categories, verify the current terms on the program’s own page rather than trusting any list including this one, and give it a full quarter before judging the results.
Frequently Asked Questions
What Are the Best Fitness Affiliate Programs?
Rather than picking by rate, multiply the commission by the typical order value. A 5% commission on a $1,500 rack pays far more than 20% on a $40 supplement tub.
Which Fitness Affiliate Programs Pay the Most?
By dollars per sale, certifications win. A $2,000 personal training course pays hundreds per enrollment, which no supplement commission approaches.
What Are the Best High Ticket Health and Fitness Affiliate Programs?
Both need genuine authority behind the recommendation. High ticket conversions come from trust rather than traffic volume.
What Are the Best Fitness Supplement Affiliate Programs?
Supplements are the strongest long-run category in fitness because customers rebuy monthly, which no equipment or apparel program matches.
What Are the Best Fitness Equipment Affiliate Programs?
That cookie length matters more than the rate, because equipment buyers commonly research for two or three months before purchasing, well past the 30-day window most programs use.
What Are the Best Fitness Apparel Affiliate Programs?
Apparel converts well on visual platforms because the product is the content, though order values are lower than equipment and demand is seasonal.
Are There Women’s Fitness Affiliate Programs Worth Joining?
Women’s fitness apparel converts better than unisex equivalents because the fit conversation is specific, which gives you something concrete to say in the content.
Can I Join Fitness Affiliate Programs With No Followers?
Marketplace access is the workaround. The brandID affiliate marketplace requires no approval and no follower minimum, so you can start with brands like THE GYM PEOPLE and Naked Nutrition immediately and apply to the bigger programs once you have traffic to show.
How Much Can You Earn From Fitness Affiliate Marketing?
The strongest setups combine a supplement program for the monthly baseline with an equipment or certification program for the occasional large payment.
Why Do Commission Rates Differ Between Websites?
Treat every figure you read, including the ones in this article, as a starting point. Confirm the current terms on the program’s own page before building content around a rate.
