1. Put the Fitbit on your dog.
    Then play fetch with your dog. Win win for both of you!
  2. Shovel.
    Which is actually a lot harder than walking. So skip this one.
  3. Drink.
    I don't mean booze. Drinking non-alcoholic beverages will work, too.
  4. Swing your arm back & forth.
    Add music & you're dancing!
