Compare the best Shopify agency for fitness brands options for 2027, with verified gym equipment, activewear and connected fitness case studies from 10 teams.
Fitness brands sell products that are hard to judge through a screen. A squat rack has to be measured against a ceiling height, a rowing machine is a four-figure purchase that people research for weeks, and a pair of leggings has to fit perfectly or it comes back. Choosing a Shopify agency for fitness brands is therefore less about who can build an attractive theme and more about who understands comparison tools, bundled memberships, sizing, product drops and international shipping for bulky goods.
The gap between good and weak options shows up quickly. Strong agencies can point to named fitness or activewear clients, explain what they changed and, ideally, publish numbers: conversion rate, average order value, organic revenue or international sales. Weak options lean on generic ecommerce portfolios and borrow the Gymshark story without having worked on it. A fitness ecommerce agency worth hiring should also be comfortable with the subscription and app layers that connected fitness products now depend on.
For this list we checked each agency’s own website for named fitness clients across gym and home fitness equipment, activewear and gymwear, and connected fitness hardware. Supplement and nutrition brands are covered in a separate list, so they were not counted here. We then ranked the agencies on Shopify partner status, the depth of their fitness work, published results and how well their services match what equipment and apparel brands actually need.

Best Shopify Agencies For Fitness Brands For 2027
1. Avex — Activewear CRO With Published Revenue Gains
Avex is a New York agency, based on Ninth Avenue in Manhattan, that describes itself as a Platinum Shopify Plus agency. Its client list is heavy with performance and lifestyle apparel, and three of its case studies sit squarely in fitness: The Shop by Equinox, swimwear and training brand TYR, and activewear label Balance Athletica.
The TYR project is a useful example of what a focused engagement can do. Instead of a rebuild, Avex ran an optimisation sprint on the existing Shopify theme ahead of Black Friday, reworking navigation, filtering, search synonyms, product badging, the slide cart and out-of-stock handling, then stripping unused scripts. Avex reports revenue up 25% and orders up 37% year on year for the quarter. For Balance Athletica it handled discovery, design, development and Klaviyo flows, including a countdown page for product drops, and reports a 168% lift in conversion rate and a 22% rise in average order value. For Equinox it audited and redesigned a store that had originally been built as a quick fix.
Avex suits activewear and apparel brands that already have traffic and want measurable gains from UX, speed and conversion work, as well as brands that need a partner for full Shopify Plus builds.
2. Domaine — Global Builds For Drop-Driven Activewear
Domaine is a remote-first Shopify Platinum Partner with offices in New York, Los Angeles, London, Amsterdam, Berlin, Toronto and elsewhere. Its fitness portfolio is among the strongest we found. For Peloton Apparel it built region-specific stores for the US, Canada, Germany and the UK, designed for collections that sell out within minutes; Domaine reports more than 250,000 sessions within hours of launch.
The agency also moved activewear retailer Bandier from Magento to Shopify, adding a personalised page, a kit builder, merchandising for its best-selling legging and visual filters, and has stayed on for ongoing optimisation. For The Sports Edit, which was shifting towards women’s activewear, Domaine rebuilt the store around richer content and faster loading, and reports a 5% rise in conversion rate alongside large improvements in PageSpeed scores.
Services cover strategy, design, Shopify theme and headless development, migrations, Klaviyo lifecycle marketing and internationalisation. Domaine is a fit for established activewear brands that run limited drops, sell in several countries and want one team to own design and engineering.
3. Anatta — Embedded Engineering Teams For Scaling Activewear
Anatta was founded in Austin, Texas, in 2008 and has been a Shopify Plus partner since 2014. It is a Shopify Platinum Partner and works with a set of fast-growing direct-to-consumer brands, including activewear brand Vuori. According to Anatta’s Shopify partner listing, it provides Vuori with a cross-functional product and engineering team of more than ten full-time staff, supporting both ecommerce and physical retail growth, with work including Checkout Extensibility and point-of-sale integration.
That model is different from a typical project agency. Anatta behaves more like an outsourced product department, combining engineering and replatforming with conversion rate optimisation, subscription and retention work, omnichannel commerce and market expansion. It also runs managed services and quality assurance as a service.
Anatta suits activewear brands that have outgrown a single developer or small agency, are opening stores, and need dependable engineering capacity on Shopify over several years rather than a one-off redesign.
4. Swanky — International Expansion Stores For Connected Fitness
Swanky is a Shopify Platinum Partner with its UK office in Exeter, Devon, plus teams in Adelaide and Montpellier. Its most relevant fitness project is for Vitruvian, an Australian smart home gym that pairs a resistance training machine with an app and a coaching subscription.
Vitruvian was paying a fee on every non-USD order through its single US store. Swanky built a Canada-specific Shopify Plus expansion store, launched in March 2023, and a back-end set-up that manages several expansion stores from one codebase. Comparing three months either side of launch, Swanky reports Canadian revenue up 100%, average order value up 33% and conversion rate up 200%, while being open that the comparison mixes two different visitor groups.
Beyond builds and migrations, Swanky covers subscriptions, B2B, internationalisation, Shopify POS, CRO, paid media, email and SEO. It is a good choice for connected fitness and equipment brands planning a move into new countries and looking for an agency that will explain the trade-offs honestly.
5. CQL — D2C Shopify Builds For Equipment Manufacturers
CQL is a Shopify Platinum Partner with an office in Chicago, and it describes itself as one of the original ten Shopify Platinum Partner agencies in the US. Much of its work is with established manufacturers and retailers, which makes it relevant for fitness equipment makers who sell through dealers and want to grow direct sales.
Its fitness case study is Lifeline Fitness, a fitness equipment brand in the Escalade portfolio. CQL rebuilt and replatformed the retail site on Shopify in ten weeks, with a new digital identity, mobile-first design, cleaned-up product data and taxonomy, SEO groundwork and content modules that explain how the products work. Just as important, CQL and Escalade created a repeatable Shopify model that can be rolled out across Escalade’s wider portfolio of equipment brands. The case study does not publish performance figures.
CQL offers strategy, total cost of ownership modelling, design, ERP and PIM integration, POS and ongoing support. It suits manufacturers running several equipment brands that need a consistent Shopify approach across all of them.
6. Limely — UK Fitness Equipment Migrations And Sports SEO
Limely is an ecommerce agency in Chester, founded in 2015, with Shopify Select Partner status alongside Magento and Hyvä credentials. That mix matters for fitness brands, because many UK equipment sellers are still on Magento and want a careful move.
For JTX Fitness, a UK gym equipment brand, Limely migrated the store from Magento to Shopify, built a mobile-first checkout, redesigned product pages around specifications, reviews and warranties, added a product comparison tool and created a Knowledge Hub of buying advice and training content. It also refreshed the brand identity. For triathlon and swimwear brand ZONE3, Limely ran technical SEO, content clusters and migration redirects on Shopify, reporting 130.7% growth in organic sessions and a 74.8% rise in organic revenue.
Limely is well placed for UK fitness equipment and sports kit brands that need a migration, comparison features for high-value products and organic search growth from one team.
7. Imaginaire — Shopify Launch Support For Fitness Hardware
Imaginaire is a Shopify Plus Partner based at Nottingham Science and Technology Park, with a separate service for Dubai and the UAE. Its fitness client is Wattbike, the indoor cycling brand.
Ahead of the Wattbike Proton and Air launch, Imaginaire spent three months extending Wattbike’s existing custom Shopify theme. The work included new homepage, hub and product page features, dynamic content blocks, a workout carousel styled like a streaming service, add-to-basket from the homepage, an app showcase and a model comparison page, together with a codebase tidy-up for performance. The case study does not publish figures, but it shows the type of work a hardware launch needs: comparison, app promotion and fast pages.
Imaginaire also offers Shopify Plus design and build, headless Shopify, replatforming, SEO, PPC and CRO. It suits UK fitness hardware brands that already have a theme and need a dependable team to extend it around launches.
8. First Pier — Growth Marketing For Strength Training Accessories
First Pier is a Shopify and Shopify Plus specialist on Commercial Street in Portland, Maine, working in ecommerce since 2009. It runs a dedicated fitness and sports industry page, and its main fitness client is Versa Gripps, the weightlifting strap brand.
First Pier moved Versa Gripps from Weebly to Shopify in nine weeks, carrying over customers and orders, and reports revenue up 66% after the move. It then took on growth marketing, scaling ad spend threefold at a 6x blended return on ad spend and growing orders 66% across direct and Amazon channels. It also worked on positioning the brand for a wider fitness market. Other sports work includes Maine Sport Outfitters, where it connected Shopify to a Lightspeed system across three shops.
Services run from Shopify development and Shopify Plus optimisation to paid search, paid social, SEO and marketplace feeds. First Pier is a sensible choice for fitness accessory brands that want build and growth marketing under one roof.
9. craftberry — Personalised Activewear Redesigns From Europe
craftberry is a Shopify Premier Partner headquartered in Varna, Bulgaria, with clients across Europe, the US, the Middle East and Australia. Its sports work includes the running brand On, golf brand Takomo and eFoil maker SiFly, and its clearest fitness case study is SWT Active, an Australian activewear brand.
SWT Active’s old site treated every visitor in the same way. craftberry rebuilt it on a custom Shopify theme with personalisation at the centre, an editorial visual style, advanced filtering and Shopify Markets for international selling. It reports a 9% increase in conversion rate and a 4% rise in average order value.
craftberry’s services include Shopify development and custom apps, UX and UI design, CRO and A/B testing, subscriptions and memberships, and migrations from a long list of platforms. It suits activewear brands that want an experienced Shopify team based in Europe with a track record of measured redesigns.
10. Lethal Digital — Shopify Builds For Smaller Activewear Labels
Lethal Digital is a Perth agency established in 2002 and a Shopify Partner, as well as a Klaviyo, Meta, Google and TikTok partner. Unusually for a generalist studio, it runs a dedicated fitness website service, and its portfolio is full of fitness names: activewear retailer Fit Society, size-inclusive activewear brand WildBody, and coaching businesses such as Mark Carroll Premium Coaching, Rachael Toohey Fitness and Lauren Simpson Fitness.
For Fit Society, a Perth activewear retailer that started online and later opened a boutique in Mount Lawley, Lethal delivered the Shopify build and design, SEO, Meta and TikTok advertising, email marketing, branding and a social media strategy. Features included rotating custom collections, branded category showcases, a live Instagram feed and customer reviews.
Lethal does not publish client performance figures, so it ranks below agencies with measured results. It is still a practical choice for Australian activewear start-ups and fitness coaches selling merchandise who want design, Shopify and paid social handled by one local team.
How To Choose A Shopify Agency For Fitness Brands
Has the agency worked on products like yours?
Gym equipment, connected hardware and activewear are very different jobs. Equipment sellers need comparison tools, delivery and assembly information, finance options and specification-heavy product pages. Apparel brands need size guides, colour swatches, drops and returns handling. Ask for a case study that matches your category, not just a fitness logo on a client wall, and ask who on the team actually worked on it.
Can they show results, not just screenshots?
A fitness equipment Shopify store or activewear site should be judged on conversion rate, average order value, revenue per visitor and returns rate. Agencies such as Avex, Swanky, Limely and First Pier publish numbers, which gives you something to test. If an agency only shows designs, ask for before and after metrics under a non-disclosure agreement and check whether the figures cover a fair comparison period.
How will they handle bundles, memberships and subscriptions?
Many fitness brands now sell hardware with an app subscription, a warranty or accessories. Others run replenishment for consumables or memberships for training content. Ask how the agency would build a configurator or kit builder, which subscription app they prefer, and how the checkout will cope with mixed carts. A Shopify Plus agency for fitness brands should be able to explain Checkout Extensibility and its limits in plain terms.
Are they ready for launches and drops?
Gymwear Shopify development often revolves around limited releases that bring huge traffic spikes in a short window. Ask how the agency load tests, how it handles stock reservation and bots, and whether it will be on call on launch day. For equipment, ask how it supports pre-orders and back-in-stock alerts when container shipments are delayed.
Do they understand international selling for bulky goods?
Shipping a rowing machine to Canada is not the same as shipping a T-shirt. Ask about Shopify Markets versus expansion stores, duties and tax, regional pricing and freight rules. Swanky’s Vitruvian work is a good example of how the right store structure can change both fees and conversion in a new market.
What happens after launch?
Most fitness brands see their biggest gains from steady optimisation after a rebuild. Look at whether the agency offers retainers for CRO, SEO, email and paid media, or whether you will need separate partners. Agree on reporting, response times and who owns the theme code before you sign. A Shopify agency for activewear brands that stays involved through the next two seasons is usually worth more than one that hands over and disappears.
Conclusion
The best Shopify agency for fitness brands depends on what you sell and how big you are. Avex, Domaine and Anatta are the strongest options for established activewear brands with heavy traffic and drops. Swanky, CQL, Limely and Imaginaire stand out for equipment and connected fitness, where comparison tools, migrations and international set-ups matter most. First Pier, craftberry and Lethal Digital offer good value for growing accessory and apparel labels that want build and marketing support together.
Whichever you choose, ask for fitness-specific case studies with real numbers and test the team on bundles, launches and shipping before you commit.
