How to use the online timer

Seconds matter wherever a minute is too coarse a measure to be useful. Interval work lives here: twenty on and ten off, forty and twenty, the fifteen-second move between circuit stations, the ninety seconds standing still between heavy sets. So do the small kitchen moments — a soft-boiled egg that wants another twenty seconds, a pan given long enough to get properly hot before anything goes in.

At this scale the tightness is the point. A ten-second rest is meant to be barely enough, and letting it stretch to fifteen changes what the exercise is doing. Counting in your head drifts within a round or two, particularly when you are breathing hard, so a countdown that holds the number exactly is the difference between the format you intended and a gentler version of it.
