First comes the innocent yoga mat, dumbbells acting as bookends, or spinning shoes jockeying with stilettos. Soon the extra blankets go to Goodwill so the storage ottoman can accommodate yoga blocks. Then a person falls in love with hula hooping, and suddenly the coffee table bearing Marilyn Monroe memoirs is a villainous obstacle, preventing one from combining core exercises with an episode of Real Housewives. Clear the floor! A home designed for motion is lighter, less cluttered, and cleaner. Funny thing: The process works in reverse. Replace your static furniture with open space, yoga mat, or trapeze, and watch your body begin to move. Need a push? Find your challenge on SocialWorkout.com.
