This cries out for an app, which uses both visual and audio cues to prompt the next exercise, and count down each period. EG: "Starting your 7 minute workout with Jumping Jacks in 5... 4... 3... 2... 1..." "Start Jumping Jacks for 30... [optional chirp-per-second]... 20 seconds... 10 seconds... 5... 4... 3... 2... 1..." "Rest now, next is Wall Sit... in 5... 4... 3... 2... 1..." "Begin Wall Sit for 30... [etc]" Obviously, it could be a static recording. But some obvious enhancements would be: • visual countdown timer • changing images of the exercises to precede/accompany each phase • optional chirps/clicks each second • alternate trainer voices • optional extra voiced 'encouragement' ("keep up intensity", "good", "almost there", "all done") • automatic logging/reminders of when/how-often circuit is completed (either based on how many times started run through uninterrupted, or based on a prompted "did you finish and what was your self-rated 1-10 intensity?" question at the end)
