HIIT — key points to know
HIIT (High Intensity Interval Training) alternates short phases of intense effort with recovery periods. The timer makes every interval clearer, more repeatable and easier to follow during the session.
What you get
A structured, readable session with clear visual and sound cues.
What changes
Less hesitation between exercises, rest periods and cycles.
What you avoid
Confusing starts, poorly timed recovery periods and improvised efforts.
Important advice: train at the planned intensity, without trying to “push harder”.
Consistency and execution quality matter more than raw performance.
