Thirty seconds is a classic length for a beginner plank, a stretch held on each side, or one interval in a circuit workout.

Frequently asked questions

How do I start this timer?

This page is already set to 30 seconds: press Start or the Space key. Press it again to pause.

Does the timer ring if I switch tabs?

Yes. The countdown is calculated from the exact end time, so it stays accurate in a background tab. When time is up, the alarm rings, the tab title flashes and, if you allowed it, a notification appears.

Can I add time while it runs?

Yes: press +1 min or the up arrow key. The down arrow removes a minute.
