How to Create A Fitness Affiliate Program for Your Shopify Brand

The global online fitness market is growing fast, with customers ready to spend billions.

Reports show that its market size is valued at a massive $257 billion in 2025 (Fitness Industry Insights).

For a Shopify fitness brand, have you ever felt that it is hard to earn shoppers’ trust?

Fitness consumers are skeptical of branded messaging because they’ve been burned by empty promises before.

Instead, they rely on recommendations from sources they already trust.

Think about it: Who do they really listen to?

They listen to the personal trainer whose transformations they’ve witnessed, the fitness blogger whose journey they’ve followed for years, or the gym buddy who’s tried every supplement on the market.

The thing is, how do you get those trusted voices to talk about your brand?

That’s where an affiliate program comes in.

It lets you partner with these people and turn them into authentic ambassadors for your brand, helping your brand grow in the fitness industry.

Plus, you only need to pay them a small commission for the successful sales that they bring.

In this guide, we will show you how to build a fitness affiliate program from the ground up.

The foundation of your affiliate program

For a successful affiliate program in the long term, you need to have a strategic plan from the beginning.

Choose a comprehensive affiliate management app

Managing your affiliate program on your own seems simple and under control at the beginning. But it can be overwhelming as your program grows bigger.

At that time, you may work with different types of affiliates, such as content creators, influencers, fitness experts, and even your customers.

Each group has a different commission rate, so you will struggle with tracking sales and updating rows for all of them.

With a lot of work to do, a sale is missed, or a payment might be late.

A manual system like that can possibly put your valuable partnerships at risk and affect your growth.

But with a top-recommended solution like UpPromote, everything is simplified.

You can create different programs for different groups of affiliates.

Our real-time analytics dashboard gives you a clear view of each group’s performance, tracking key metrics like clicks, sales, referrals, and commissions.

You can also save hours of manual paying affiliates with UpPromote’s auto-payout via PayPal or with Store Credit.

Moreover, our support team is available 24/7, so you can ask any questions or get expert help with technical issues.

You can experience these robust features and more with a 14-day free trial across all plans. You can test if our app works well with your program with no risk before committing.

Design a competitive commission structure

A competitive commission structure can effectively attract high-quality affiliates to join your program.

However, setting the right commission rate for your products requires a lot of research on the industry.

So, we’ve analyzed data from over 124 fitness brands. Let’s take a look at the common patterns among these brands to find out which rate is suitable for your program.

For fitness equipment and accessories, the standard commission is 5-10%.

Don’t worry about 5% is a low commission. It is still a generous offer for affiliates since these products are high-priced ($1000-5000).

Think about selling a $2,000 treadmill. A 5% commission still puts $100 in your affiliate’s pocket.

If you sell supplements and nutrition, the commission should jump to 10-20%.

Promoting these products requires a deep level of credibility because they directly impact consumers’ health and well-being.

They have to create detailed content, explain the science simply, or even share their own results. So, a high commission is fair for their effort.

For example, famous fitness brand Optimum Nutrition UK offers 12% commission on their dietary supplement.

When it comes to fitness apparel and footwear, we suggest setting the commission at around 8% to 15%. 

Customers need to consider the colors, sizes, and fabrics before buying fitness apparel. So, affiliates need to invest more in their promotions to truly generate sales.

For example, Onnit offers up to a 15% commission on their fitness apparel.

That means if affiliates successfully generate an order of $250 leggings, they earn $37.5. That’s a fair payout for their effort.

Finally, if your Shopify brand provides fitness online courses, the commission should be as high as 20% to 40%. 

The reason is pure profit margin. Once you’ve created a digital workout guide or a fitness app, the cost to deliver it to a new customer is literally zero.

Natalie Jill offers up to 30-50% commission on their digital books and coaching sessions.

If affiliates can generate over 10 subscriptions to their $40 fitness digital books, it’s $200 commission a month.

Set a suitable cookie duration

A cookie duration directly affects the chance of affiliates getting credited for a sale.

When a customer clicks an affiliate link, a tracking cookie is placed in their browser. If they purchase within the cookie window, your affiliate earns a commission.

So, if it’s too long, you might end up paying for over-attributed sales, which could affect your final profits. But if it’s too short, you risk cutting off valuable partners.

Fitness supplement & accessories: 20-30 days

For fitness supplements and accessories, a 20 to 30-day cookie duration is suitable because it perfectly aligns with the customer’s refill cycle.

Think about how people actually buy products like protein powder or pre-workout.

They rarely purchase a new tub when they still have a full one at home.

Instead, a customer sees an affiliate’s recommendation and thinks, “I’ll try that next time I run out.” They might have another two or three weeks’ worth of their current product to finish first.

For example, a top supplement retailer like Myprotein sets a cookie duration of 30 days on their sports nutrition products.

Fitness equipment & subscription courses: 60-90 days

But for high-ticket fitness items and services ($500-3000), you need a longer window.

A cookie duration of 60 to 90 days is essential for products that require more research.

Imagine an affiliate creates a detailed video review of your $2,500 smart home gym.

A customer will not buy that on impulse. They will watch the video, then spend the next month reading other reviews and comparing models before finally committing.

For example, Perform Better offers a 60-day cookie duration for their training equipment. Meanwhile, LifeSpan set a 90-day cookie duration on their home workout machines.

Recruit the right fitness affiliates for your affiliate program

Working with the right affiliates can significantly boost your Shopify store’s sales.

We’ll help you identify who they are and how to recruit them effectively.

Identify your ideal affiliates

Your ideal partners are the ones who have an audience that perfectly matches your fitness brand.

First, you can consider working with experts like fitness trainers and coaches. 

Their authority is built on their deep understanding of performance and function.

This is why their recommendations are so effective at guiding what fitness shoppers decide to buy.

For example, a trainer may feature your resistance bands in a “how-to” workout video and explain exactly why the tension is right for glute activation.

Or, they can write a long and detailed review of your training machines on their own blog.

Besides experts, you can work with fitness influencers to strengthen online awareness of your brand.

Their value is not technical expertise, but aspiration and connection. They won’t explain the squat-proof technology of your leggings.

Instead, they will post a “Get Ready With Me” video for the gym, making your apparel part of a desirable routine.

They promote by showcasing a lifestyle. Their followers buy because they want to feel that same confidence and be part of that identity.

However, there are a lot of fitness and health influencers across different platforms. You might be confused about whether to partner with macro or micro ones.

Your affiliate program is new, so micro influencers are a better option since it’s easy to reach out to them, and their average engagement is considerable.

We’ve found some potential names on Instagram for you to check:

• @the.fit.ma (355.8k followers)
• @venus2bfab (285.1k followers)
• @rena_serenaa (248.4k followers)
• @noelarevalo_ (236.5k followers)

You can check out their profile and content carefully. If you find them suitable for your program, you should send a warm message and naturally talk about the collaboration offers.

Reach out to your right affiliates

After identifying who you should work it, it’s time to invite them to join your program effectively.

The first approach is proactive outreach to fitness influencers and bloggers.

These people have already built the trust and the audience you need to reach. But they get dozens of partnership offers a week.

A generic and copy-paste email will be deleted instantly. So, your message must be personal and show you’ve actually seen their content.

You can mention a specific workout video or recipe post you liked to spark their interest in your email. Then, you can naturally talk about the collaboration offers.

Here is a simple template you can adapt:

Turn your loyal customers into affiliates

The second approach is to activate your most powerful advocates – your own customers.

Their recommendations are genuine because they’ve already spent their own money on your products.

When they tell a friend about your pre-workout, that recommendation carries a different kind of weight. It is pure, authentic social proof.

So how do you encourage this natural behavior? The best way is through a referral program where both the customer and their friend get a benefit.

Imagine a customer joins your program and recommends their friend to buy your fitness supplement.

That friend ordered via the customer’s referral link and got a 10% discount. In the meantime, the customer can earn 10% for that purchase as well.

With UpPromote, you can customize a widget on your website to show this amazing offer to your customers.

Your customers don’t need to fill in a long registration form or wait for approval.

They only need to provide their email address to be part of the program. Our system will automatically generate an invite link, so the customer can copy and send the link to their friends.

Equip affiliates for better sales performance

Your fitness affiliates know how to promote your products. However, they also need high-quality and brand-aligned promotional assets to deliver better content.

Provide high-quality marketing materials

A professional media kit is the tool that they need, helping them share your brand quickly and consistently.

A great marketing kit should always come with visually appealing images.

A blurry photo won’t sell a high-performance product. You need to give them sharp photos of your protein tubs on a clean background for their blogs.

Moreover, it’s a great idea to provide action shots of your apparel during a real workout.

We also suggest adding short video clips of your pre-workout being mixed, which are perfect for Instagram Reels or TikTok.

It’s even better if you prepare your affiliates with ready-made banners for specific fitness seasons, like a “New Year’s Resolution” challenge or a “Summer Shred” promotion.

Beyond visuals, they need the right caption and product descriptions for their posts.

You don’t want them to make up some exaggerated caption on your products. It can ruin customers’ trust in your fitness products.

For your supplements, you should provide the key selling points: the clean ingredients and the muscle recovery benefits.

For your apparel, tell them what matters: is it sweat-wicking? Squat-proof? Describe the fit and feel.

With UpPromote’s Media Gallery, you can create a professional library with all of the above assets within a few steps.

You can organize each type of asset in specific categories, so your affiliates can find what they need faster.

Set up a unique coupon code

You should give affiliates a unique discount code to help them generate sales more easily and effectively.

You can use UpPromote’s Auto-generate coupon to set up the discount code for affiliates.

The system will automatically generate coupons based on your pre-set rules.

You can choose the coupon format of Affiliate’s name, Affiliate’s first name, or Random letters. Then, you can set up the discount number for all coupons.

When a new affiliate joins the program, our app will assign a new coupon with their name.

For example, an affiliate named Rachel joined your affiliate program. A coupon code with her name, “TEAMRACHEL15”, will be directly assigned to her.

Foster ongoing communication with affiliates

You should consistently communicate to show your dedicated support to affiliates. If they feel neglected, they’ll lose energy and focus on other brands instead.

The easiest way to stay connected is by using monthly newsletters. A regular program update makes affiliates feel refreshed and ready for the next promotion.

In this newsletter, you should let them know what matters: the new vegan protein flavor just launched, your Black Friday sale is coming up, or which leggings were the top-sellers this month.

This information helps them create timely and relevant content.

Instead of emailing everyone one-by-one, you can use UpPromote’s Bulk Email feature to send one message to all of your affiliates with a single click.

Motivate affiliates with bonuses

Affiliates need motivation to put more effort into promoting your fitness products. You can easily stir up their energy with limited-time bonuses.

Setting up a bonus for your affiliates is easy inside UpPromote.

You only need to set the target type, target amount, and the bonus rate. Then, you can set up the bonus period as one-time, monthly, or quarterly.

And, our system will track affiliates’ progress and automatically send the bonus after they hit the goal.

Let’s say the holiday season is approaching and you want to push gift sales.

You could set a $100 bonus for any affiliates who bring 20 sales for your new smart water bottles in December.

You can set the target (20 new sales) and the bonus amount ($100). Then, you can set up the bonus period to be monthly, starting from December 1st.

Conclusion

We hope that this guide has everything you need to start your fitness affiliate program. It’s the perfect time for your brand to grow bigger in this competitive market.

It’s definitely overwhelming at first since there are various new and complex tasks to do. But UpPromote can do all the heavy lifting for you.
