ReFit : AI-Powered Fitness & Rehab App for Students

ReFit: AI-Powered Fitness & Rehab App for Students

Staying healthy is tough for students balancing classes, projects, and personal goals. Gym memberships and personal trainers are often expensive, and most fitness apps are designed for advanced users or require costly wearables. On the other hand, students dealing with injuries (like shoulder or knee issues) often don’t have easy access to physiotherapy guidance.

My idea is to create an AI-powered fitness and rehab app designed specifically for students and young professionals in India. Using just a smartphone camera, the app would:

  • Track workouts in real-time with OpenCV/ML to analyze posture, reps, and form.

  • Offer personalized fitness plans for fat loss, muscle gain, or rehab (like shoulder mobility).

  • Recommend low-cost diet options tailored to the user's food preferences.

  • Provide AI-driven corrections (e.g., “your back isn’t straight during push-ups”).

  • Include a community feature where users can challenge friends or join college fitness groups for motivation.

This directly benefits students and budget-conscious individuals who want guided training without paying for gyms, trainers, or expensive devices. It also helps those recovering from injuries by giving safe, guided rehab exercises.

This problem matters to me because I’m currently in rehab, dealing with a shoulder issue. I know how important it is to have the right guidance without spending a fortune. By combining my CS skills, interest in AI/ML, and personal fitness experience, I want to create a tool that makes health and recovery accessible to everyone.

  • Nice concept, using AI for fitness and rehab is super relevant. Just make sure the posture tracking stays accurate across different phone cameras, small errors there could mess up form or cause injuries.
  • This is a truly amazing concept! AI has the potential to significantly improve student access to fitness and rehabilitation. It is both entertaining and useful because of the community challenges and real-time form correction. Another great thing about it is that it emphasizes affordability without sacrificing guidance. I'm eager to watch ReFit grow!
  • This is an impressive and meaningful idea! You’ve clearly identified a real problem that affects many students and young professionals. Using AI and computer vision to make fitness and rehab guidance more accessible — especially without expensive wearables — is a smart and impactful approach. The personal motivation behind your project adds authenticity, and the inclusion of community challenges makes it even more engaging. This has great potential to genuinely help people stay fit and recover safely on a budget.
  • This idea makes a lot of sense, especially for students who can’t afford gyms or physio sessions. Maybe you could also think about adding verified expert input or simple progress tracking so users don’t rely only on AI for form correction.
  • The concept presents a compelling solution, addressing the critical need for accessible and affordable fitness and rehabilitation guidance tailored for students and young adults. The utilization of AI to facilitate this initiative is particularly innovative. Furthermore, the integration of a community feature offers a valuable mechanism for fostering motivation and engagement. We are eager to observe the future developments of this promising project.
  • A very creative and useful solution to an often overlooked problem. I think this truly reflects an example of real-life problem solving.
    • I also think this initiative is often overlooked and much needed for the students of India, considering the lack of focus on given to physical activity. That’s what I mean when I say this is a great example of real-life problem solve . Good luck
  • This is such an amazing idea! I really love how you’re using AI to make fitness and rehab more accessible and affordable for students.
  • Great idea! Refit addresses a real gap for students by combining AI fitness guidance with rehab support. Excited to see how this concept can make fitness and recovery more accessible.
  • This is such a great idea! Affordable and accessible fitness and rehab guidance for students and young adults is so needed, and it’s really cool that you are able to use AI to make it happen! The community feature is a great way to add motivation and I can’t wait to see where you’ll take this!
