I’m building an online hub where gym-goers can film a set, upload it, and instantly receive AI feedback on form, tempo, and suggested tweaks. Beyond that moment-to-moment coaching, the site will log every workout, surface progress analytics, and generate personalized routines that adapt as each member grows stronger. A social layer will let users join challenges or simply show off a newly conquered PR. The interface must feel personal. More than being merely clean or pretty, it should let members pick themes and color palettes so the environment reflects their taste and keeps them motivated session after session. On the technical side, I need: • A responsive web app that accepts video uploads and streams them through a pose-recognition model for real-time guidance. • Secure user accounts, subscription handling, and payment gateway integration for premium tiers. • Scalable architecture so the platform stays snappy as the community expands. • A robust data layer that tracks workouts, then feeds the recommendation engine driving our adaptive plans. • Community features—profiles, progress posts, leaderboards—that encourage healthy competition. Acceptance criteria will centre on model accuracy, interface responsiveness, and the ease with which a user can switch themes without touching a settings tutorial. When you respond, highlight relevant experience—especially projects that combine computer vision, fitness tech, or highly customizable front-ends. If your background shows you can balance AI complexity with a flexible, user-centric design, we should talk.
