How to use the Tabata Timer
- Adjust the duration with the +/- buttons if you need something other than 20 seconds.
- Press Start to begin the countdown.
- Use Pause and Reset anytime to stop or restart the countdown.
- When the timer reaches zero, an alarm sounds automatically. It works well for interval-style training — set it, start your set, and let the alarm tell you when time is up so you can stay focused on the movement.
