Physical activity contributes to good appearance and posture. Strength training exercises improve muscular tone. When abdominal muscles are tightened, you stand more erect. Physical activity helps to maintain desirable body weight by using up calories which otherwise might be stored as body fat.

Physical activity also improves the cardio-vascular system. Endurance training improves the efficiency of the heart and decreases the pulse rate.

Engaging in the sports and games is fun for anyone of any age. The pleasure and the enjoyment of physical effort contributes in an important measure, to ‘joie de vivre', and zest for living.

Relief of mental and emotional tensions and the social pleasures associated with games, sports, or other forms of physical activity are well recognized for their effect on general well-being.

The ‘fit' individual can live a more productive life. He can work for greater periods of time without undue fatigue. In addition, he is likely to respond more effectively to emergency situations which maybe encountered in everyday life.

There are many ways that you can ‘inject' activity into your everyday life without changing into shorts or going near a gym.

Always take the opportunity to use the stairs in your office building whenever you can. Avoid the elevator. You may not be able to walk all the flights the first time but eventually you will.

Don't fight for the parking space nearest the front door of the office building or store. You will be less tense, if you look for a space some distance away, and will find it easier to park. A short, brisk walk to your place of business will set you up for the day.

Even while dressing or undressing, stand rather than sit. While drying yourself after a bath or shower, place the towel behind your neck or back or under your foot and push hard against the towel.

Whenever you can think of it, pull in your stomach, tighten your shoulder and back muscles. It's good for you and you'll look better too.

Don't be pulled along behind your power-driven lawnmower-push one. It may take a little longer but it's good exercise.
