Running is a method of terrestrial locomotion allowing humans and other animals to move rapidly on foot. Running is a type of gait characterized by an aerial phase in which all feet are above the ground (though there are exceptions). This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion. A characteristic feature of a running body from the viewpoint of spring-mass mechanics is that changes in kinetic and potential energy within a stride occur simultaneously, with energy storage accomplished by springy tendons and passive muscle elasticity. The term running can refer to any of a variety of speeds ranging from jogging to sprinting.

Many people often tend to think that injuries are caused mostly because of overtraining. They're not, and are arguably caused by small imbalances in the muscles of the athlete's legs. Many professional runners, including world-renown Zola Budd, prefer to use methods involving kinesiology to fix such problems. Ms. Budd is now 48, and just won her age group in South Africa's largest ultra marathon: Comrades!

Cross-training is a beneficial way to train. It is great for those days when you want to mix up your routine due to monotony or as a challenge. As a runner, even on your "off days" you can find exercises that are going to contribute to your technique, stamina, and body mechanics.
