I used firestick for Cathe since day one when they started On Demand and Live. I LOVE IT!!! Yes, you get all the premixed for Cathe's workouts plus her blender lets you make your own workouts using the chapters in each of her workouts. You can also share your blender workouts and download workouts from others. It is the best thing ever. With the On Demand, you get Live included which is great too. I sometimes find myself doing mostly live workouts during the month instead of dvds. It's so easy to use. If you do this, just remember that when you "blend" your own workouts, that needs to be done on a laptop or desktop computer. Then when you log into your app, the workout will be there. I hope that makes sense. If you have any other questions, let us know.
