At the airport

Dress for action. Don't let uncomfortable footwear — or clothing — keep you grounded. Wearing supportive shoes and packing a small roller bag (or checking your luggage) can free you up to roam during your layover, and rack up healthy steps.

Fun game: Try walking alongside the moving sidewalk, and "racing" the people on it.

Check out airport exercise facilities. Perfect for stretching your limbs between flights, a growing number of airports are now carving out space for in-terminal yoga rooms. Some even offer virtual golf.

If you have serious time to kill, it may be worth exploring options for a full gym workout. A few airports feature designated gyms and some airport hotels offer day passes for a small fee. Search online for "airport gyms" to find current offerings.
