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.
