Teardown: Gymshark — how a billion-dollar brand still leaves 6 obvious CRO fixes on the table

Gymshark is one of the canonical Shopify Plus case studies. Founded by a 19-year-old in a garage in 2012, valued at over $1B a decade later. It's the store every founder benchmarks against. So of course we pulled out the stopwatch.

What surprised us is that even at that scale — with what must be a sizeable internal tech team — there are still six meaningful CRO gaps sitting on the store. Not "we'd do this differently" preferences. Actual leaks. Let's walk through them.

What Gymshark does right

1. The navigation is opinionated

Most Shopify stores at scale let the menu balloon. Gymshark keeps theirs ruthlessly focused: Women / Men / New / Collections / Sale. That's it. For a store with ~2,000+ SKUs, this is disciplined merchandising.

2. Product photography is the product

You can't undersell this. Gymshark's lifestyle imagery is cinematic, consistent, and creates identity far beyond "gym apparel". The PDP uses 6-8 images per product — front, back, detail, lifestyle. For apparel CRO, image volume + quality is the single biggest conversion lever.

3. Sizing tools that actually get used

Gymshark's size guide isn't a PDF. It's an interactive tool that asks height, weight, fit preference, and returns a size recommendation per product. This eliminates returns (cheap) and saves revenue (expensive). The cost to build it is trivial compared to the lifetime reduction in return rate.

What we'd fix

Fix #1 — Mobile homepage LCP is 4.1s (mobile 4G)

On a throttled mobile 4G test, the homepage LCP is 4.1s. Target is under 2.5s. The culprit: a full-screen video hero that loads immediately on mobile. For many users, the video has barely started by the time LCP has already failed.

Fix: serve a static poster image as LCP, lazy-load the video element after the page is interactive. Video quality barely matters if users never see it. This alone should pull LCP under 2.5s.

Fix #2 — Add-to-cart doesn't always open the cart drawer

On some PDPs, adding to cart fires a confirmation toast but doesn't open the side cart drawer. Users have to manually click the cart icon to see their added items. This is a missed upsell surface — and we suspect it's a remnant of a split A/B test that never got resolved.

Fix: consistent cart drawer open behavior site-wide. Then use the drawer real estate for 1-2 relevant upsells (accessories, socks for gym wear, etc). Even a modest 10% attach rate on an accessory upsell is a meaningful AOV lift at this volume.

Fix #3 — No urgency signals on sale items

The Sale page is a big revenue category. But there are no signals of scarcity — no "low stock" badges, no countdown to sale end, no "X people viewing this". These aren't dark patterns when used honestly: a sale that genuinely ends at midnight Sunday should say so.

We tested urgency timers on limited drops and saw +14% CVR. On a sale category, the lift is usually smaller (+6-8%), but it's practically free to implement.

Fix #4 — Email capture is a full-page interstitial

First-visit triggers a full-screen "join our list" interstitial before the user has seen any product. This is the opposite of what works. Users need signal (quality photography, product range, trust) before they care about your email list. Moving this to an exit-intent trigger, or a bottom-right non-blocking corner modal, typically captures similar email signups without the CVR tax of blocking the first page view.

Fix #5 — Checkout is missing a clear trial / guarantee statement

Gymshark has a 30-day returns policy, but it's mentioned only in the footer. By the time a first-time buyer is entering their card, a trust signal right there (like Wakefit's trial-as-hero approach) would catch hesitant buyers. We'd test a single-line "30-day free returns — we got you." between shipping and payment. Based on similar tests on apparel checkout, +3-5% conversion is a reasonable estimate.

Fix #6 — Product reviews don't filter by body type / size

For apparel, the question a buyer wants to answer is "will this fit someone like me?" Gymshark's reviews are generic — name, stars, comment. They don't structure by height, weight, or size purchased.

Fix: structured review intake asking body type at submission; surface filters ("reviews from 5'7-5'10 buyers", "reviews from size M buyers") on the PDP. This turns review count into review signal — the higher-trust signal. Expected conversion lift on apparel: 4-7%.

TL;DR

Gymshark is a world-class brand whose CRO fundamentals are strong. But even at a billion-dollar scale, there's a layer of conversion wins sitting on top of the existing experience — worth probably 10-15% combined on site-wide revenue if executed well.

The lesson for smaller stores: if even Gymshark has six obvious fixes, your store has at least twelve. Start with speed (mobile LCP under 2.5s), then work through the funnel one friction point at a time.
