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. If you want to follow along with your own workout videos, build a simple tracker with a video player and progress charts, using this register's fitness-tracker build spec as the foundation — a genuine, achievable weekend project for content you already have the rights to.
