Movement is so important that when my northern clients leave for the summer or any of my clients go on vacation that includes a long car ride, I send them off with some moves they can use for the long trip. Get out of your vehicle at least every two hours. I know you're anxious to get where you're going, but I want you to get where you're going. The longer you sit, the higher the risk of developing blood clots, the hip flexors get tight and short, creating stress to the low back, the low back has to 'prop' up the weight of the top half of the body further increasing the stress. In short, keep moving! Reduce the amount you sit. When driving long distances, stop every couple of hours and walk briskly for 10 to 15 minutes. Do some lengthening moves that require spinal elongation while proping your hands on the trunk of your car. While in your car, put on some great music and 'dance' in your vehicle, tap your toes, wiggle your shoulders, bob your head, slid your ribcage side to side. Of course, this as the passenger in the vehicle! Always drive safely and keep moving!
