HIIT Timer
About the HIIT Timer
HIIT lives or dies on honest work-rest ratios, not vague I will go hard for a while. This HIIT Timer alternates intense work windows with short recovery so heart rate spikes and drops on schedule instead of whenever you feel tired. Boot-camp instructors project it on a gym wall, home athletes pair it with bodyweight circuits, and runners use it for hill repeats with strict walk-back rests. Round counters show how many cycles remain so you finish the session you planned.
How to use it
- Open the HIIT Timer page and review default work and rest intervals for this sport profile.
- Set work length, rest length, and total rounds to match your program or coach sheet.
- Label the drill, station, or round type in the task field before starting.
- Press start when the set begins and let the timer advance work and rest phases automatically.
- Use fullscreen and sound alerts so transitions stay sharp even when you are fatigued.
Good to know
Intervals are a training aid, not medical advice. Stop if you feel pain, dizziness, or chest tightness. The clock only helps if the tab stays open and you can hear or see the change of round.
