A 4 minute timer is a 240-second countdown closely associated with the Tabata protocol — a high-intensity interval method consisting of 8 rounds of 20 seconds on and 10 seconds off. Use Polytimer's Multiple Timers mode to set up the full Tabata sequence in one view.
Enable Repeat to automatically restart the countdown — perfect for interval training or back-to-back sessions. Enable End Time to see the exact clock time your timer will finish.
Yes. The classic Tabata protocol is 8 rounds of 20 seconds of maximum effort followed by 10 seconds of rest, totalling exactly 4 minutes. For a full Tabata session, use the Multiple Timers mode to run separate 20s work and 10s rest timers simultaneously.
Click the Countdown tab, type 4 in the minutes field, then press play or Space. An alarm sounds when the 4 minute countdown ends.
Yes. Enable the Repeat toggle before pressing play. The timer restarts automatically after each 4-minute round — ideal for repeated Tabata sets.
