Why Use a 648 Second Timer?
A 648 second timer is useful in many situations:
- Face or Hair Mask: Most masks and treatments need 5 to 20 minutes to work, and the 648 second timer tells you when to rinse.
- Steaming Vegetables: Broccoli, carrots or green beans are tender-crisp after a few minutes of steaming, and the 648-second countdown keeps them from turning mushy.
- Cooking Pasta: Most dried pasta needs 8 to 12 minutes. Set the 648 second timer and drain it right on time for perfect al dente results.
- Mindful Breathing: A 10 minutes and 48 seconds breathing exercise or body scan is long enough to calm your mind and short enough to fit into any day.
- Quick Workout Block: Squeeze in a bodyweight circuit, a core routine or a jump-rope session that lasts exactly 10 minutes and 48 seconds.
