9. Batting Cage
You can practice your swing for a team if you’re on one, or relive the glory days of your youth. Either way, you’ll likely have to concentrate so hard on the ball coming at you that you won’t have time to think about how you’re getting some exercise. Just be sure to wear a helmet.
10. Walking
This doesn’t have to be a purposeful stroll. Park at the back of the lot when you go to the store. Walk over to your co-worker to tell them something in person rather than send an email. When you take out the trash or pick up the mail, keep going around the block. All those steps add up.
