Why this preset exists

Tabata training is a specific form of HIIT popularized by Japanese researcher Izumi Tabata. It consists of 20 seconds of all-out work followed by 10 seconds of rest, repeated 8 times for a brutal four-minute total. Because the intervals are so short, timing accuracy is everything — a 20-second interval is impossible to eyeball reliably.

A clear way to use it

  1. Warm up thoroughly — Tabata is intense and demands prepared muscles.
  2. Pick one exercise, such as squats, push-ups, or sprints on a bike or rower.
  3. Start the timer and give full effort for each 20-second work period.
  4. Rest for 10 seconds, then repeat — 8 total rounds makes one 4-minute Tabata set.
  5. Cool down afterward and judge whether another set is appropriate for your training plan and current condition.
02 / Make it yours

Adjust when needed

  • Count your repetitions per round so you can try to beat your previous number.
  • Use low-impact options (rowing, cycling) to reduce joint stress during all-out efforts.
  • The researched Tabata protocol used very high effort with trained participants. Choose a safer intensity and exercise when that context does not match you.

Useful questions

How many Tabata sets should I do?

The original study used one set of 8 rounds with trained participants on cycle ergometers. That does not prescribe a safe set count for everyone; use a plan appropriate to your experience and health.

What makes Tabata different from regular HIIT?

Tabata uses a fixed 20/10 ratio and demands true all-out effort. Regular HIIT uses longer intervals like 40/20 and can be sustained at a slightly lower intensity for more rounds.
