How recovery tracking works
Built tracks every exercise you perform and maps it to specific muscle groups. Based on the volume (sets × reps × weight), intensity, and time since your last session, the app calculates recovery levels for each muscle group individually.
This data is visualized through color-coded heatmaps on an anatomical body view: red/orange indicates muscles still recovering (fatigued), while gray indicates fully recovered muscles ready to train.
- Real-time muscle heatmaps: Color-coded visualization of every major muscle group's recovery status
- Individual tracking: Each muscle group recovers independently based on training volume, intensity, and time
- Smart decisions: Know when to push hard and when to dial back before you overtrain
How AI coaching works
Built's AI coach doesn't just tell you what to do, it explains why your workout changes, adapts based on your recovery, and helps you learn how to train smarter over time.
- Recovery-aware programming: AI reads your muscle recovery data and adapts workout volume and intensity accordingly
- Real-time guidance: Get form tips, rest recommendations, and progression advice during your workout
- Learn the system: The AI explains why it makes suggestions so you develop training intuition over time
How the social feed works
Built is like Strava for the gym. Instead of guessing what program your friend follows or how that influencer trains, you see their actual workouts, exercise selection, and recovery patterns.
- Real workout data: See exactly what exercises, sets, reps, and weights people use
- Recovery visibility: Understand how training volume affects recovery for different people
- Learn from paths, not just results: See the process that builds physiques
