Move 1 of 6 · Round 1 of 3
The presets match the programs exactly: the beginner circuit is 30 seconds of work, 15 of rest, six moves, three rounds with 90 seconds between rounds; the HIIT session is the Tabata-style 20/10 over four moves and four rounds; the outdoor circuit is 45/15 over five stations and three rounds. Sound cues mark every work and rest switch, so the phone can stay in a pocket. For a session of your own rather than one of the three, the circuit builder assembles one and sends it here with the station names attached, so the screen says what you are doing instead of which number you are on.
