The classic Tabata interval: 20 seconds all-out, 10 seconds rest, on a loop. Eight rounds is four brutal minutes — pick any exercise (squats, burpees, mountain climbers) and go as hard as you can each work step.

How to use it

  1. Choose one exercise and get into position.
  2. Hit Start and give maximum effort for the 20-second “Work” step.
  3. Rest completely for the 10-second “Rest” step — you’ll need it.
  4. Count off eight rounds (four minutes), then stop.

Make it yours

The 20/10 split is the standard, but you can tap either step to adjust it. For a longer finisher, keep looping past eight rounds. Prefer an automatic stop? Turn Loop off and add eight work/rest pairs in the sequence editor so it ends on its own.

FAQ

What is Tabata?

Tabata is a high-intensity interval protocol: 20 seconds of maximum effort followed by 10 seconds of rest, repeated for 8 rounds — four minutes total. This timer runs all eight numbered 20/10 rounds and chimes at every switch, then stops on its own at the end.

Do I have to count the rounds?

No — this preset is the full eight rounds, so it ends automatically after four minutes. Each work and rest step is numbered (Work 1 … Work 8) so you always know where you are. Want a longer session? Turn Loop on in the options, or add more rounds with the quick-timer chips.
