About the Workout Timer

Free workout timer for exercise blocks, circuits, stretching, cooldowns, and gym sessions. Start a 30 minute timer or use the interval timer.

TimerHub calculates remaining time from an absolute finish timestamp, so missed browser callbacks do not create drift. Read the timing accuracy methodology and reproducible tests.

Common Uses

  • Circuit training
  • Stretching
  • Cooldowns
  • Gym sessions
  • Fitness challenges

How to Use the Workout Timer

  • Press Start — or the Space bar — to run the 30 minute countdown. Space also pauses and resumes it; R resets it
  • Adjust by 1 minute with the +/- buttons while it runs, toggle Repeat to loop it, and check the finish time shown under the display
  • Use the Fullscreen control below the timer for a room-sized countdown (Esc to exit)
  • Choose or mute the alarm in the header's sound settings, and pick a background sound — rain, ocean, fireplace or brown noise — that fades out at zero
  • Enable notifications to be alerted when your workout timer finishes in a background tab, and add ?autostart=1 to the link to start the countdown on load
