If you've ever started an outdoor activity carrying a filled-water bottle (and of course you're never without one, right?!), you know that cold becomes tepid very quickly.
With the exception of hot chocolate or Strawberry Quik, not much tastes worse during a summer-into-fall sweaty workout than lukewarm water.
What to do? The night before your workout, while you're laying out your tank top and shorts, be your own beverage consultant, too.
Fill a water bottle three-quarters full and pop it into the freezer. In the morning, add more water to the chunk of ice in your bottle. As you walk or run or cycle or skateboard, the ice will melt into cool water and quite possibly last all through your workout.
When the temperatures drop (which they will, really!), only fill the bottle halfway before freezing. By winter, maybe just a fourth. Then as the seasons do their changing, the days their lengthening, you can start working your way up to freezing the bottle when it's three-quarters full again.
Grateful for the spins of the earth, for life's constants – and for cool water during a September workout – that's us.
