with and damage biological components critical for the normal functioning of the cell including nucleic acids proteins, and lipids leading to a condition know as oxidative stress. Free radicals that contain one or more unpaired electrons. An example is the hydrogen atom, with one proton and one electron, free radicals are also found in nitrogen. These are mainly produced in the mitochondria, which utilize most of the oxygen consumed for metabolism and ATP production. This rate increases twenty times during exercise causing bodily harm [11]. Studies continue to show that it is never too late to start exercising and that even small improvements in physical fitness can significantly lower the risk of early death. Simply walking regularly can prolong life in the elderly. Moderately fit people, even if they smoke or have high blood pressure, have a lower mortality rate than the least fit. Resistance training is important for the elderly, because it is the only form of exercise that can slow and even reverse the decline in muscle mass, bone density, and strength. Flexibility exercises help reduce the stiffness and loss of balance that accompanies aging [1]. Conclusively, the benefits of exercise far out weight the negative side effects that are sometimes recognized with exercise. The risk of exercise such as injuries, oxidative stress, and disorders can be avoided with an exercise regime that is personally appropriate. Overtime one will notice many significant gains due to exercise and begin to feel more energetic, youthful, and be able to handle the daily demands of life. People of all ages should be involved in some sort of physical activity in order to maintain a healthy lifestyle....
