Derny connects to your indoor training equipment so Muse can create, edit and organize structured workouts. Useful for planning intervals and sessions for a bike trainer, treadmill or elliptical, then keeping them arranged in one place.

Example request: "Make me a 45 minute interval workout for my bike trainer with a warm up and five hard efforts."
