I spend a lot of time commuting, and I'm usually the driver or a passenger in a car, so I can't get out and walk around. Are there any ways I can keep the blood moving, especially in my legs?
The expert answers:
You didn't mention whether you are doing mostly highway driving or city driving. If it's highway driving, then it is very difficult to keep the blood circulating in your driving leg (unless you're using the Cruise Control feature on your car). But, for your other leg, you can try doing ankle circles as well as isometric contractions of your thigh and calf muscles by simply tightening and releasing those muscles in a rhythmic fashion.
If you're doing city driving, then use opportunities such as red lights and stop signs to do ankle circles and isometric contractions in both legs, alternating, obviously, between each leg. When you're the passenger in the car, you can also do these exercises periodically. In addition, you can extend one leg in front of you and push your foot into the floorboard, tightening all the muscles in the leg, then relax that leg and switch to the other one.
