What Is Tabata?
Tabata is a form of high-intensity interval training (HIIT) built around a simple, brutal ratio: 20 seconds of all-out work, 10 seconds of rest, repeated 8 times. A full round lasts just 4 minutes, making it one of the most time-efficient workouts you can do.
The key is a timer that switches work and rest phases automatically — which is exactly what ORA Timer’sinterval mode does, with a sound cue at every switch so you never lose your rhythm.
