Tabata timer

Why Tabata is 20 and 10.

A Tabata round is eight rounds of twenty seconds of hard work and ten seconds of rest: four minutes in total. The rests are too short to recover fully, which is the point, and they are also too short to count reliably in your head while you are out of breath. A timer that calls every change is what makes the format usable.

✦ What it is for

What people use a Tabata timer for.

A four-minute finisher

One Tabata round at the end of a session.

✦ How to

How to use the Tabata timer.

1

Set work, rest and rounds

It starts at 20 seconds of work, 10 of rest and 8 rounds. Pick a preset or change any of the three underneath the timer.

2

Press start

A 10-second countdown gives you time to get into position, then the first round begins with a tone.

3

Follow the tones

A higher tone starts each work period and a lower one each rest, with ticks for the last three seconds. The round count shows how many are left.

4

Finish

A chime marks the end of the last round. Press go again to repeat the whole set.

Every week

Four minutes today. A routine by next month.

The start-calisthenics plan is three short sessions a week with next to no equipment, and progressions that make a first pull-up a date rather than a hope. It installs in one click.
