Most of my workouts are fairly time-sensitive - I need to get in, get done, and get out in a certain amount of time, and the timer helps me do just that. Our timer has a count-up mode (i.e., it counts up continuously like a stopwatch) as well as a count-down mode (e.g., you set the timer for 5 minutes, and it will beep or flash when the time is up), and these are common features that you’ll find on most kitchen timers. I typically use the count-up feature, but many people prefer to use the count-down mode instead to keep track of rest periods.
