Change it up
Many exercises can benefit from a periodic change in direction or exercise variation. This tool will call out 'change' periodically, based on your settings. This could be used to change direction in a warmup sequence, or change to the next station in a circuit training session, for example.
Regular timing: 10 seconds.
Keep this page open and your screen awake. Stop to change settings or begin a new exercise.
Delay
Choose the usual time between "Change" calls, using minutes and seconds. For example, 0 minutes and 30 seconds means a call roughly every half minute.
Delay randomness
Choose how much the timing varies. At 0, calls follow a steady rhythm. At 10, the gap can vary from half to twice your chosen delay.
Exercise duration
Choose how long the exercise should last, using minutes and seconds. The tool stops automatically when this time is up. The countdown and any time spent paused are not included.
Countdown start
Choose Yes to hear "3, 2, 1, Go!" before the exercise begins. Choose No to skip the countdown. Once the exercise begins, there is a waiting period before the first "Change" call.
Start
Begin the exercise, or continue an exercise you've paused.
Pause / Resume
Take a break. Both the exercise timer and the wait until the next call pause with you. Press Resume or Start to continue.
Stop
End the exercise and reset the timer. Pressing Start again begins a new exercise.
