fitxclash

Inspiration

Many people know the importance of staying fit, but traditional workout routines often feel repetitive and boring. We wanted to create a platform that combines the excitement of gaming with fitness, making workouts more engaging and motivating. The idea behind FitXClash was to transform exercise into a competitive and interactive experience where users enjoy staying active instead of treating it like a chore.

What it does

FitXClash is a real-time multiplayer fitness platform where users participate in short workout battles, perform exercises, and compete against opponents through live scoring. The platform uses AI-powered pose tracking to count repetitions and monitor movements directly in the browser without requiring gym equipment or external devices.

How we built it

We built the frontend using React, TypeScript, and Tailwind CSS to create a smooth and responsive interface. Framer Motion was used for animations and transitions to give the application a game-like experience. For pose detection and repetition tracking, we integrated MediaPipe computer vision. The backend was developed using FastAPI and WebSockets to support real-time multiplayer communication and synchronized score updates. Deployment was handled using Vercel and Railway.

Challenges we ran into

One of the biggest challenges was optimizing real-time pose tracking while maintaining smooth UI performance. Managing WebSocket synchronization between multiple players with minimal latency was also difficult. We additionally faced deployment and CORS configuration issues while connecting frontend and backend services securely.

What we learned

Through this project, we gained practical experience in:

Real-time multiplayer architecture Browser-based computer vision WebSocket communication Performance optimization Full-stack deployment and scaling

We also learned how gamification can significantly improve user motivation and engagement in fitness applications.

What's next for fitxclash

In the future, we plan to add:

AI-powered posture correction Personalized workout recommendations Leaderboards and streak systems Additional game modes and exercises A mobile application for better accessibility
