Running cardio from your watch

The live screen for a cardio exercise: a running (or counting-up) clock, the prescribed machine settings, and your heart rate if it's available.

What this screen shows

The top line shows which segment you're on and its prescribed settings (speed, incline, level — whatever applies). The big number counts down a timed segment or counts up an open-ended one, turning gray while paused. Below that, either your live progress toward a distance goal (outdoor cardio) or a preview of the next segment's settings, and your heart rate in bpm when the watch can read it.

Step by step

START pauses or resumes the clock.
DOWN skips straight to the next segment.
Timed segments auto-advance on their own — a lap vibration and tone cue mid-workout, and a stronger double-vibration and tone when you reach the last segment's goal. That last one is a cue, not a stop: the clock keeps counting, now upward, so if you want to keep going you just keep going. Reaching a distance goal works the same way, since real-world pace varies. Either way you end the exercise yourself from the menu.
MENU or BACK opens the cardio menu: resume, finish this cardio exercise, skip to the next segment (interval cardio only), jump to another exercise, finish & save the whole workout, or discard it.

Good to know

If a workout is being run from both devices and the other one finishes this cardio exercise first, your watch hands off to the next exercise on its own — you don't need to do anything.
