Exercise is an activity that should be undertaken by all individuals, on a regular basis -- the exception being individuals who have been advised by their physician to not exercise. A physical exam is highly recommended before beginning an exercise program.
Children usually get exercise through playing at home, at school, and in extracurricular sports. As we get older, though, our amount of physical activity decreases. For most adults it is practically nonexistent. Lack of physical activity is one of the primary risk factors for several serious diseases, the most serious being heart disease.
There is good news, however, for those diagnosed with a serious disease. Exercising may prevent or improve the state of diseases individuals may suffer. It is never too late; one is never too old. Often I have individuals tell me that it is too late for them or that they are too old to begin exercising. As a fitness professional, one of my responsibilities is to help individuals separate fact from fiction. I say this with certainty: one is never too old and it is never too late. I explain to them that exercise is the key to the fountain of youth. It has been proven through scientific research that exercise benefits the human body in many ways, both mentally and physically.
One of the simplest of exercise programs an individual may undertake is a walking program, which improves the cardiovascular system, the single most important element of physical fitness. It is also a good way to strengthen the lower body muscles, bones, and connecting tissues.
When walking outside, dress appropriately and wear comfortable shoes and clothing. Start by walking a short distance, at a comfortable pace, for five to ten minutes. Try to increase the amount of time by a couple of minutes each week, working your way up to 45 minutes to an hour total.
An important tip to remember: Listen to your body. If you feel out of breath, slow down your pace and decrease the amount of time that you walk. In time, you will be able to walk faster and for longer distances.
It would be wise to consult with a trained fitness instructor before beginning an exercise program. The instructor will be able to help you design a program centered around your current level of fitness, goals, and objectives. If I may help you, please call me at 725-8883.
