Running on hard land or pavement is very stressful for your joints. This is why you see so many ex-track stars with knee and back problems later on in their lives. Every time you run you are thrusting your joints will the impact weight of your entire body mass. Joints are not bones, they are not meant to withstand extreme pressure constantly. If you are a big jogger, or competition runner, it is very important that you train on a machine like the elliptical trainer.
The way that it's built, allows for an almost entirely impact-free workout. You can increase the time that you exercise for, and increase your results. No more taking days off from cardiovascular because of aching joints, or stiff back muscles. The reason that it hurts your back when you run, is because your spine is being crunched together and then stretched back out over and over again. Think of a cardboard box. Now imagine you stepping on the top of the box for a couple seconds. What is going to happen to one or all of the sides?
They are going to collapse under the weight of your body-right? That's what happens to the joints in your spine when you are bouncing up and down on a treadmill or running on the road. When you suspend in air for that one stride, and then come back down on one of your feet, there is no magical bungee cord system that allows your tailbone to drop down into your pelvis momentarily and bounce back into place. What happens is that the joint fluids between the bones in your spinal column, are pinched together to create room for the impact of your weight on them. When you exercise on an elliptical trainer, the pedals that your feet are resting on go downwards in a circular motion, so there is little to know impact on your back. The same goes for you knees.
Avid exercising has almost always meant that you will experience some kind of chronic pain in the coming years that you begin to age. Using an elliptical will relieve unwanted pangs of muscle stress and fractions.
