Question 1

What is a Tabata workout?

Accepted Answer

Tabata is a high-intensity interval training (HIIT) protocol created by Dr. Izumi Tabata. The classic format is 20 seconds of maximum-effort work followed by 10 seconds of rest, repeated for 8 rounds — a total of 4 minutes per exercise.

Question 2

How do I use the Tabata timer?

Accepted Answer

Pick a preset or customize your work/rest durations, number of rounds and prep countdown, then press Start. The timer will announce each work and rest phase with a visual ring and audio beeps, automatically advancing through all rounds.

Question 3

Does the timer work without internet?

Accepted Answer

Yes. The Tabata timer runs entirely in your browser using JavaScript. Once the page has loaded, it works offline. Your custom settings are saved locally so you don't have to re-enter them next time.

Question 4

Will I hear sound cues between intervals?

Accepted Answer

Yes. A short beep plays 3 seconds before each phase change and a longer tone marks the start of work, rest and the end of the workout. Make sure your device is not muted.

Question 5

Can I change the work and rest times?

Accepted Answer

Absolutely. Click Settings to adjust work seconds, rest seconds, number of rounds, cycles, rest between cycles and a prep countdown. You can also pick from built-in presets like classic Tabata, HIIT, EMOM and 30/30.
