Interval Timers

Intervals. This is a generic interval setting of 30 seconds at low intensity, followed by 30 seconds at high intensity completed by a 30 second rest. You can repeat it as many times as you want.

Tabata. A Tabata is a specific interval workout of 20 seconds of work followed by 10 seconds of rest, repeated 8 times. What exercises can you do in a Tabata? Well, pretty much anything, but we recommend you pick something easy. You'll be repeating it a lot for about 4 minutes.

Custom. Start with any interval timer and you can add/remove intervals; change interval intensity; and of course change the number of sets.

Basic Timers

Countdown. A countdown is the simplest a timer can be. It's one interval of any duration. It's great for a warm-up, a run or a cool-down.

Stopwatch. Not all exercises should be time-based. Some should be work- or rep-based. For those you can use a stopwatch.

Understanding the Visuals


Timers are represented visually with bar charts. Here's what you need to know:

  • Y-axis is the intensity of the interval.

  • X-axis is the duration of the interval.

In the graph above all intervals are the same duration, but they are all different intensities.
