Intervals
Calculate your tabata time, then start the timer.
A classic tabata uses 20 seconds of work, 10 seconds of rest, and 8 rounds for a four-minute block. Change the work, rest, rounds, or sets below and the calculator will show the full session length before you train.
Start with a preset or make your own
Tabata works best when the movement is simple and the clock is clear. Pick a preset, then adjust the numbers for the session in front of you.
How long is a tabata workout?
Eight rounds of 20 seconds work and 10 seconds rest take four minutes. Add preparation, multiple sets, or recovery between sets and the total session becomes longer. The calculator includes all of those parts.
How many tabata rounds and sets?
Start with the classic eight-round block. One or two hard blocks are enough for most sessions when the movement is demanding. Use more sets only when technique remains consistent and the extra work has a clear purpose.
