How to use the online timer
Every minute on the minute: a set piece of work starts at the top of each minute, and whatever is left of that minute is the rest. Ten minutes, ten rounds. The format is self-regulating in a way most others are not — work faster and you earn more rest, work slower and the rest disappears, which makes it brutally honest about pacing.
Choose the work so that it takes roughly thirty to forty seconds at a steady pace. Anything that eats fifty seconds in the first round leaves nothing by the sixth, and the session turns into a continuous effort by accident. The countdown runs in this browser tab, so keep the page open where the minute marker can be heard rather than watched.
The number to record is the round at which the rest started shrinking, because that is where the load or the rep count needs adjusting for next time. It is also a format that suits shared equipment: two people can alternate minutes on the same bar or machine without either standing idle, which matters in a small building gym in the evening.
Common questions
What happens if the work takes the whole minute?
Then there is no rest, and the session becomes continuous by accident. Choose work that takes about thirty to forty seconds at a steady pace so the format keeps its shape through all ten rounds.
What should I record afterwards?
The round where the rest started disappearing. That is the point where the load or the rep count needs adjusting next time, and it is more useful than how the session felt at the end.
