Impromptu fitness is the best.

Sometimes the best workouts are unplanned. For example, after a dark and stormy morning, Sunday's weather blossomed into clear skies as temperatures soared to beachworthy levels. To capture what was left of our day, my husband and I threw our bikes in the back of the Escape and ventured over to the new Arnold Palmer golf course here in town. Though it's still a work in progress, the course is absolutely stunning. And the cart path is everything but level. Holy hills—impromptu fitness, indeed!

I definitely started to feel it in my thighs, and without my padded bike shorts, my buns started to burn. My husband, on the other hand, was fine because his seat is very much a throne. In the end, we pedaled and pushed our bikes over about 10 miles of golf course peaks and valleys. It was a workout, indeed. But it didn't feel like one. And that's why impromptu fitness is the best—because it almost never feels like a workout but it's still totally good for you. So tell me, when was your last impromptu fitness session?
