Practical Uses for a 397 Second Timer
People use a 397 second timer for very different tasks, for example:
- Warm-Up & Cool-Down: Five to fifteen minutes of light movement before and after training prepare your body and help it recover.
- Speeches & Pitches: Rehearse lightning talks, elevator pitches or class presentations with a visible 397-second limit.
- Mindful Breathing: A 6 minutes and 37 seconds breathing exercise or body scan is long enough to calm your mind and short enough to fit into any day.
