Your fitness influencer agency for campaigns, ambassadors & UGC

A fitness influencer agency connects brands in categories like supplements, sports nutrition, fitness apparel, apps or gyms with fitting fitness creators — and manages the collaboration from creator selection through briefing and content review to reporting. The difference from a generalist agency: it knows the scene's sub-niches, the ambassador models common in the niche and the category's particularities, for example in supplement advertising.

At creatorhub there is one more layer: we manage creators from the fitness scene ourselves and have been in the creator business since 2019. We select for training credibility rather than reach alone — and will tell you honestly if a different route would do more for your brand.

Fitness influencer campaigns at creatorhub start at €5,000 — including strategy, creator matching, campaign management and reporting. Creator fees depend on reach: nano-influencers (1,000–10,000 followers) charge €50–250 per post, micro-influencers (10,000–50,000 followers) €250–1,500, mid-tier creators (50,000–250,000 followers) €1,500–5,000. Standalone UGC production starts at €1,500.

Hybrid models combining a fixed fee with commission on discount-code sales are also typical for the fitness niche — especially in ambassador programs. Whether and in what split that pays off depends on your margins and goal; after a short briefing you will receive a concrete proposal.

Supplements need creators whose training credibly matches the product — strength and functional-fitness profiles for creatine and protein, for example, and running or endurance creators for electrolytes and bars. More important than follower count is whether the community believes the creator actually uses the product: someone who visibly trains and has shown what they take for years recommends more credibly than a bigger generic profile.

Two criteria we always check: category exclusivity — a creator who switches protein brands every three months is credible for none of them — and the profile's existing ad density. Both feed into our shortlist before you see a single name.

As a rule of thumb: the one-off campaign is the test, the ambassador program builds trust. A single post shows you whether creator, message and audience fit together — but purchase decisions in the fitness niche often only happen once the community has seen a product in the creator's training routine for weeks. That is exactly what an ambassador program with fixed creators and a dedicated discount code delivers.

In practice we combine both: we start with a test campaign across several creators, measure code redemptions and move the strongest profiles into the long-term program. That way your budget flows to where it demonstrably works.

Health-related claims for supplements and sports nutrition are strictly regulated in the EU: the Health Claims Regulation only permits authorized statements, and sweeping promises like “burns fat” are off-limits. On top of that, ad disclosure applies — ambassador posts with a discount code are advertising too and must be labeled as such.

We brief creators on compliant claims and review content before it goes live — that is a fixed part of our campaign management, but it does not replace legal advice. Final sign-off on your product claims sits with your brand and its legal counsel.

Yes — with a different mechanic than for product brands. For gyms, chains and local businesses, national reach matters less than creators with a community in the catchment area: local fitness creators whose followers actually train in the region. Formats like training vlogs from the gym, challenge activations or trial-session codes make the effect measurable.

Honestly: how many fitting local creators exist varies a lot from city to city. Whether your location has enough potential is something we check in the briefing — before any budget is spent.

For generic content: yes. The tenth interchangeable transformation reel and discount-code posts without any real product connection drown in the noise. For brands with a clear positioning the answer is still no — precisely because the niche has grown so large, almost every product has a sub-community where credible recommendations work.

The consequence for creator selection: better the mid-sized creator whose community follows every training session than the huge profile that promotes everything. That is exactly the logic behind our shortlists — and we will tell you honestly if your product needs sharper positioning first.
