Set the timer to 65 seconds

How to use the online timer

Rest periods matter as much as the work itself, and 65 seconds is a common gap between rounds in a lot of interval training. Start it the moment you finish a set, use the time to catch your breath and grab some water, and get ready to go again as soon as it counts down to zero. Watching a clock never feels as precise as letting the timer call it.

There's no setup beyond pressing Start, and the countdown handles the rest on its own from that point. Since it runs inside the browser, keep the tab open for the timer to keep an accurate count; you can switch to other tabs in the meantime, but closing this one out resets things. When the countdown hits zero, a sound plays so you're not stuck staring at the numbers.

Setting an egg timer or fumbling with a phone app both work, but neither is as quick as a browser tab you already have open. There's no app store, no update prompt, and no login screen between you and starting the count. It's free and needs no registration, it works on any device with a browser, and closing other tabs won't affect it as long as this one stays open. Set a timer for 65 seconds, set the timer to 65 seconds, start a 65 seconds timer — it is the same countdown either way.
