greatest benefits of exercises..

For the greatest benefit, 20 to 30 minutes of aerobic activity three or more times a week and some type of muscle-strengthening activity is recommended, along with stretching at least twice a week. If you are unable to maintain this level of activity, however, you can gain substantial health benefits by accumulating 30 minutes or more of moderate-intensity physical activity a day, at least five times a week.

The chart above demonstrates how some of the things you do every day can help fulfill that requirement. If you look at fitness as a lifetime pursuit, with everything you do contributing to it, even dressing your child or repairing your car's engine can be part of your "fitness philosophy."

Another way to make sure you get the exercise you need is an easy one - walking. It is not as strenuous as other forms of exercise, such as tennis or jogging, and you'll reap obvious benefits, whether you're a senior citizen or a teenager. You'll get more restful sleep, even if you've historically had trouble sleeping. You 'll also experience a release of tension and stress and a feeling of overall wellness. Walking can also result in weight loss when combined with a proper diet.
