This is especially important if you feel soreness in your muscles or are overly tired. A day or two of missed run is better than subjecting your already fatigued body to a possibility of injury. Listen to your body well and take note of pain, or any other hint, that tries to communicate it is not up for the challenge. A neutral-arched foot shows a distinct curve along the inside of the foot, which connects the heel and the toe. This type of foot pronates normally, meaning that when the foot lands, the outside of the feet rolls inwardly in order to absorb shock. The mid-ached foot, in comparison, rolls far too inward so that the print shows a slight curve along the outside of the foot. Personal trainers are professionals who are knowledgeable and well-trained about assisting people to appropriately execute exercises. Through their help, safe and effective training programs can be achieved. They are accredited to provide assistance to physical trainers within or sometimes outside the premises of the gym. Enhances mood When running, the body produces a substance called endorphin (endogenous morphine) that creates a different sense of euphoria. This state of euphoria is called runner s high basically because after running, individuals are in a good mood, are happier, and indescribably feel better. Runner s high is also believed to be responsible for the runners seeming addiction to running: Because they are always intensely post-euphoric, runners keep running every chance they get. Some of them add two to three miles after every week of training, while others have an easier approach, only adding a few more strides at the end of every run. But because your body works differently, you can design or look for a training plan that can help you increase your mileage at a proper intensity. Running helps lower blood pressure by maintaining the elasticity of the arteries. During a run, the arteries get exercised as well, what with all the blood moving about. Running also maximizes the lung s potential, keeping it strong and powerful. Deep breaths force the lungs to use more tissues, but half of both are unused.
