Tabata & Interval Training Timer
Tabata is a form of high-intensity interval training (HIIT). The classic protocol is eight rounds of 20 seconds of all-out work followed by 10 seconds of rest. Set your own work, rest, rounds and prepare time to match any interval workout.
How it works
The timer counts down a short prepare phase, then alternates work and rest for the number of rounds you set, with a distinct color and beep for each phase so you never have to look at the screen.
