Used to be great, but since a recent update workouts have lost all of their useful functionality. Before you could easily see the current and upcoming exercises, time remaining, and there were lots of useful interaction, such as skipping or cutting short exercises, repeating them, etc. You didn't need to listen to the sound to keep track of your workout progress. Now workouts are literally just a static video, this app is less useful than YouTube for workouts. No functionality at all.
