For most people, exercise plays a huge role in weight control and fitness level. Men and women who successfully maintain a healthy weight after losing weight, or who never really have a problem with their weight, tend to be people who are physically active. Regular exercise empowers you to improve your weight status and fitness level because it uses up excess calories that otherwise get stored in your body as fat. But that's not all exercise does. Exercise can also:
Weight-lifting and weight-bearing exercises (pulling, pushing, pressing, pumping) strengthen your different muscle groups.
Boost your energy levels.
Aerobic exercises, including fast walking, swimming and bicycling, build up your cardiovascular endurance, while push-ups and other weight bearing exercises build up your muscular endurance. More endurance means more efficient and sustained delivery of oxygen and nutrients to every cell in your body.
Improve your mood.
Exercise, particularly at a level of intensity that you prefer, has been shown in studies to improve mood, even after just 15 minutes of physical activity.
Suppress your appetite.
Active people have better control over their appetites, at least in the short-term, than sedentary people.
Reduce the effects of stress.
Exercise has consistently been shown to improve resilience
to stress and protect against the harmful effects stress can have on both physical and mental health
