The Benefits of Regular Exercise
In recent years many people have become increasingly aware of the need for physical fitness. Almost everywhere people turn, whether it is to a newsstand, television or billboard, advice for guarding and improving health bombards them. Much of this advice is commercially motivated by those eager to sell vitamins, natural foods and reducing devices and gadgets. However, some advice, especially that advocating a regular exercise program, merits serious attention. Such a program, if it consists of at least thirty minutes three times a week and if a person's physician approves it, provides numerous benefits. Regular exercise releases tension, improves appearance, and increases stamina. (Put the thesis at the end of the introduction. This makes sure that the essay’s main point is first in the reader’s mind as the reader begins the body of the essay.)
The first of these benefits, the release of tension, is immediate. Tension builds in the body because of an accumulation of excessive adrenaline produced by stress, anxiety, or fear.* Doctors agree that performing calisthenics or participating in an active sport such as tennis or volleyball for thirty minutes releases tension. If a person swims, jogs or rides a bicycle for half that time, he or she should sleep better at night and have a better temperament the next day. In addition, after the release of tension, petty irritations and frustrations should be less troubling.* For example, an employee upset by the day's work and by traffic congestion may rush home, argue with the family, and eat excessively. Taking about thirty minutes to release frustrations through physical exercise could help him or her to avoid this behavior. Planned physical exercise, therefore, can eliminate, or at least control, tension.*
An improved appearance, which is a second benefit* of regular exercise, is not as immediately visible as a better mood.* Exercise takes perhaps a month or longer to show its results in a trimmer, firmer figure. Improvement, however, will come. A person who is ten pounds overweight, for instance, may be able during this time to burn away most excess fat and to tighten muscles, thereby reshaping the physique. Having improved muscle tone and even posture, he or she will wear clothes more attractively and comfortably. Combined with a sensible diet, an exercise program will also improve a person's skin tone. This improved appearance will provide confidence and impress other people.
In addition to* the self-confidence that comes from an improved appearance, increased physical strength produces better physical condition.* A stronger, healthier body is obviously more capable of working harder. In fact, a person in good shape is better able to withstand normal fatigue then a tense, weak person. A worker who exercises should be able to complete a forty-hour week and still retain enough energy for mowing the grass, painting the garage, or cleaning windows. Similarly, the student who goes to school, keeps house and perhaps works part time should accomplish tasks efficiently. Equally important, this stamina helps to ward off illnesses such as colds and influenza. Altogether, improved endurance is one of the most important benefits of a regular exercise program.
Although easy solutions to the goals of losing weight and achieving an attractive, energetic body saturate the media,* actually acquiring these benefits is not easy. The rewards, however, are fully worth the effort of an established exercise program that makes a person feel relaxed, look healthy, and have adequate strength for strenuous as well as routine activities. *
