You should be able to pause timer during interval workout and back out to see the overview of the workout.

I noticed that when you use the timer function when I have something like a circuit prescribed, you can't back out and see the overview of the workout. So my clients do the first superset fine, but then they don't know what the next two exercises are. They have to wait for the timer to get to that exercise (they may need to prep/find equipment/lock down equipment/etc. for the other exercises). and if they do stop the timer, they have to start all over.
