Combat poor circulation, swelling, sore joints and lethargy on cramped flights by doing a short exercise routine. At the very least, you'll entertain your fellow passengers.
Step One
Squeeze a tennis ball, a racquetball or even a pair of socks with your hands until they're tired.
Step Two
Keep the balls of your feet planted and raise your legs using your calf muscles. If this is too easy, place your carry-on bag on your knees. Continue until tired.
Step Three
Plant your heels firmly and raise your toes as high as possible. Hold for five seconds, and relax. Repeat until tired.
Step Four
Place your hands on your armrests and raise your knees slowly (together is harder than one at a time) toward your chin. Lower them slowly. Repeat until tired.
Step Five
Cross your legs. Rotate the dangling foot in as wide a circle as possible. Continue until tired.
Step Six
Stretch your neck by keeping your chin close to your throat and tilting your head forward. Roll your head from one shoulder to the other, but avoid rotating it backward.
Step Seven
Flex your trapezius muscles by doing shoulder hunches. Lower your shoulders, and then raise them up toward your ears into a shrug. Hold for five seconds. Continue until tired.
Step Eight
Arch your torso gently backward and forward like a cat.
Step Nine
Flex your gluteus muscles and hold for as long as possible. Squeezing your rear like this may occasion strange glances, but these muscles are the biggest in the human body and need to be exercised, too.
* When aisles are relatively empty and the seatbelt sign is off, walk around, stretch and do lunges. To lunge, take a big step (about half your height) and gently lower yourself as far as you can while keeping the torso upright and back leg straight. Return to a standing position by stepping either forward with the rear foot or backward with the front foot. Repeat. Once you become skilled, you'll be able to work up a sweat (and an audience) lunging to the toilet and back.
