Questions
What is a Tabata workout?
Tabata is a form of high-intensity interval training named after Izumi Tabata, who studied it with speed skaters in the 1990s. It is 8 rounds of 20 seconds of maximum effort followed by 10 seconds of rest, 4 minutes in all. The short rests are the point, so keep them short.
What exercises work well for Tabata?
Moves you can do hard and safely when tired, such as squats, burpees, mountain climbers, high knees, or a bike or rowing machine. Pick one move for all 8 rounds, or alternate two.
Can I do more than one block?
Yes. Set Sets to 2 or more for repeated blocks, with a rest between them. A minute is common. The timer keeps count of the round and the set for you.
Can I change the 20 and 10?
You can, and the timer remembers it on this device. For other work and rest times, the interval timer starts from a more general workout.
What keyboard shortcuts are there?
Space starts and pauses, N skips to the next part, R resets, F goes full screen, and M turns the beeps on or off.
Is anything sent to a server?
No. The timer runs in your browser. Nothing you type is sent anywhere.
