How to use the 90 second timer

This 90 second timer counts down from 1:30 and plays an alarm at zero. If you searched for a 1 minute 30 second timer, you're in the right place: it's the same length.

  1. Press Start or hit Space.
  2. When the alarm sounds, press R to reset to 1:30.
  3. Press F for full screen so you can read it from a distance.

Rest between sets

In strength training, rest periods of about 60 to 90 seconds between sets are common. A timer stops rests from quietly stretching to three or four minutes while you check your phone. Start it as soon as you rack the weight.

Other things that take a minute and a half

  • Short talks. Practice an elevator pitch, a self-introduction or a speech segment and see if it fits.
  • Class activities. A quick partner share or a timed answer. For longer activities, the classroom timer has big digits and a custom message.
  • Holds and stretches. A longer plank, a wall sit, or a stretch held on one side.
  • Kitchen. Short heating or resting steps when instructions say 90 seconds.
