<p><b>Startup description</b></p><p>My product is a developer-focused fitness infrastructure platform that provides exercise data, workout content, exercise instructions, and animated exercise media through a single REST API.</p><p>The project was started after identifying a common problem among fitness app developers: obtaining high-quality exercise databases, media assets, and structured workout content is expensive, fragmented, and time-consuming. Existing solutions are often overpriced, difficult to integrate, or limited in functionality.</p><p>My platform solves this by offering a subscription-based API that allows developers to integrate fitness content into their applications within minutes rather than spending months building and maintaining their own exercise database.</p><p>The platform currently serves paying subscribers and continues to grow through organic search traffic and developer-focused content marketing.</p><p><b>Key Highlights</b></p><ul> <li>Monthly Recurring Revenue (MRR): €311</li> <li>Annual Recurring
