What is Tabata training?
Tabata is a high-intensity interval training (HIIT) style consisting of 20 seconds of maximum-effort work followed by 10 seconds of rest, repeated for 8 rounds (4 minutes total). You can adjust the work, rest, and round settings above to build a custom HIIT timer for any workout.
How to use this timer
Set your prepare time, work interval, rest interval, and number of rounds, then click "Start." A beep sounds at each transition so you can keep your eyes off the screen during your workout.
