3. Gardening
You might not think of it as exercise, but if you dig, bend, and clip around your garden for 30 minutes or so, you’ll get a decent workout. And it may even put you in a better mood. If you don’t have a plot of your own, consider volunteering at a community garden. They can probably use the help.
4. Geocaching
If you like to take walks with a purpose, look online for secret “geocache” spots in cities, parks, or along hiking trails. You follow clues, usually GPS coordinates, to track them down. You could find a prize in the cache or sign your name in a journal that proves you were there.
