How it works
The original Tabata protocol: eight rounds of 20 seconds all-out work and 10 seconds rest, four minutes total. Do one round of a single hard movement (squats, burpees, bike sprints) at max effort.
- 20 seconds maximum-effort work
- 10 seconds rest
- Repeat for 8 rounds (4 minutes)
- Pick one movement and go truly all-out — Tabata only works at high intensity
