Business Challenge
FitLab streamed live fitness sessions from mobile devices across multiple gym rooms, but lag and desynchronization caused participants to view different workout stages simultaneously. Thousands of members needed personalized daily plans that trainers could not assign manually, while sharing workout results on social media produced blurry, unimpressive content.

- Automate daily personalized workout plan generation.
- Eliminate repetitive workout suggestions for members.
- Reduce manual trainer planning at scale.
- Enable branded, high-quality social progress sharing.
- Support dynamic device joining without session disruption.
