Can I code this? A Subscription Fitness Content App
The app half — tracking, logging, a video player — is genuinely buildable, this register proves it. A continuous studio production of new, professionally-instructed classes is content production at real scale, the same moat as Peloton's.
Just pay
Effort: not worth startingRunning cost: $8–$16/mo
Why CanICodeThis says Just pay
A workout log with stats and progress charts shares this register's fitness-tracker build spec
For following along with workout videos you already own or can license individually, a simple player is a real weekend project
Basic streak and achievement tracking is straightforward
The parts that'll cause problems
A continuous studio production of new, professionally-instructed classes is content production at real scale, not a database of videos
Licensing a large existing fitness video library involves real content deals, not code
Live class features (real-time leaderboards for thousands of simultaneous participants) need real-time infrastructure of their own

The build prompt
Don't try to build a licensed fitness content studio — build the tracker instead:
1. A workout tracker with a video player, sharing this register's fitness-tracker build spec as the foundation.
2. Progress charts and streak tracking.
3. Play content you have the rights to through the same player.
That's a genuine, achievable weekend project for content you already own. Out of scope, and the actual point of this entry: a large licensed content library represents real content deals, not a coding problem, and live classes with real-time leaderboards need genuine real-time infrastructure layered on top of video playback.
