4. Fly a stunt kite. If there's a good wind blowing, buy a stunt kite and take it to the beach or other large open space. These kites can be easily assembled, then taken apart, making them perfect for traveling. You'll give your upper body a great workout as you struggle to control the kite. You may also have to run or walk to keep the kite in the air – or chase it down once it plummets to the earth.
5. Choose a cruise. It's amazing how active you can be while stuck on a boat in the middle of the ocean. Most cruise ships offer numerous options for seaworthy exercise. Many have pools, golf simulators, climbing walls, fitness centers, jogging and walking areas and instructor-led fitness classes – and that's just what's on board. During any ocean and land excursions you can burn calories as you snorkel, hike, scuba-dive and horseback ride.
6. Get out of the car every 2 hours. Many of us spend a large part of our vacations on the road, either getting to and from our destinations, or using the car for sightseeing. But no matter how beautiful the scenery is, great, memorable trips don't happen in a car seat.
Don't wait for exhaustion or the call of nature to get you to pull over. Get out frequently and stretch, walk, picnic, shop, visit and have fun. It's important for your health and energy, and it makes traveling a lot more interesting.
