Aaptiv allows you to download classes so that you can play them at anytime, regardless of whether you have a network connection or not.
To download a class, tap any workout to see the Workout Details screen. Tap the Download button (it looks like a cloud with a down arrow in it). To remove a workout from your downloads, follow these same steps for a workout that is currently downloaded.
To find your downloaded workouts, tap on your avatar in the upper left-hand corner of the screen to open the side bar. From there tap on Saved workouts. From the Saved Workouts screen, tap on Downloads to see your downloaded workouts.
