45 second timer
A free 45 second timer for work intervals, drills and quick kitchen jobs. It loads at forty-five seconds so you skip the dial on a phone timer, and Repeat keeps rounds coming without a tap. Also searched as 45 sec timer, 45 seconds timer.
What 45 seconds is for
- 45/15 intervals. Forty-five seconds of work and fifteen of rest is a favorite for circuit classes because it allows 10 to 15 reps of most movements. The HIIT timer page compares it with 40/20 and 30/30.
- Boxing drills. Many gyms use 45-second rounds on the bag for beginners before moving to the three-minute standard. Shadowbox between rounds.
- Sauce reductions and emulsions. Whisking a vinaigrette or finishing a pan sauce often needs about 45 seconds of constant attention.
- Elevator pitch, long version. Forty-five seconds is enough for a problem, a solution and a request.
- Wall sits and hollow holds. A step up from the 30 second timer once thirty feels easy.
Repeat for intervals
Tick Repeat and the 45 seconds restart about a second after each alarm. For true 45/15, the gap is too short to rest in, so use the 15 second timer on Repeat and count beeps: three for work, one for rest. That trick works for any scheme built on a 15-second base.
Sample 45/15 session
| Round | Exercise | Work | Rest |
|---|---|---|---|
| 1 | Squats | 45 s | 15 s |
| 2 | Push-ups | 45 s | 15 s |
| 3 | Reverse lunges | 45 s | 15 s |
| 4 | Mountain climbers | 45 s | 15 s |
| 5 | Plank | 45 s | 15 s |
Three times through takes 15 minutes. Not medical advice; scale the work to your fitness. To time a single effort instead, use the stopwatch.
