Propusher is a coaching platform for building workouts and delivering them to clients through a synchronized mobile app. This app lets a coach browse their Propusher exercise library, author exercises with 3D skeletal animations, and assemble workouts, questionnaires and multi-week programs in their own account. Everything created here appears immediately in the Propusher web dashboard and in the client's mobile app. Access is scoped to the signed-in coach's account through OAuth; the app reads and writes only that coach's exercises, workouts, questionnaires and programs, and never deletes them.
