There are three types: neutral-arched, mid-arched (overpronators), and high-arched (underpronators). One way of identifying your foot type is by checking your footprint. 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. Lower cholesterol Also according to a study, runners generally have lower cholesterol. When running, HDL cholesterol (the good fat) level increases, while the bad fat and triglyceride levels decrease. This results in reduced risk of heart diseases. 4. Stronger lungs Running makes your body more in need of oxygen, prompting your lungs to work harder by using 50% of otherwise unused lung potential. Common Mistakes In Running Running is one fairly common and simple athletic activity that most people can pick up anytime. In truth, most of us are already familiar with running. We think that starting a running program is also just as simple. We simply start to run the next day, with resolve that we will do it regularly from now on. After you get your doctor s permission, begin to implement your plan of losing weight through running gradually at first. For some, walking for a short period of time is a good start. Walking will first help you improve your cardiovascular health. After which, you may begin to do some slow jogging. Follow this up with running after a time. It starts out slow (skipping a run or two) and without your knowing it, gradually moves to a point where you notice you are not running regularly anymore. Goals One of the better ways to fight loss of motivation is to set realistic goals. One of the more common goals to stay motivated is simply to complete a race. Weight loss For all its boring features, running is very effective in allowing a person to burn an average of 100 calories for every run mile. Biking and walking, on the other hand, only burn a fraction of these calories in the same amount of time. While we burn around 2000 to 5000 calories every day doing nothing, running 5 miles a day burns an additional 500 calories.
