Additional information

How to use the interval timer

Choose a HIIT, Running or Circuit preset, or set your own effort duration, rest duration, number of rounds and preparation time.

Then press Start: the workout screen shows the current phase, remaining time, current round and next phase.

What workouts is it useful for?

This timer works well for interval training, short circuits, bodyweight exercises, running workouts, HIIT sessions and simple routines alternating effort and rest.

Good to know

Rest is placed between rounds, but not after the final one. The sound cue can be enabled or disabled before starting the workout.
