How Tabata works
The original Tabata protocol alternates 20 seconds of maximum effort with 10 seconds of rest, repeated 8 times (4 minutes total). You can adjust any of these values.
The tool moves on its own between prep, work and rest, showing the current round and alerting with a sound at every phase change.
Worked example
With the default values (20s work, 10s rest, 8 rounds), the full session lasts 4 minutes, not counting prep time.
