in Healthy Lifestyle
Did you know that the RDA - Recommended Daily Amount - of physical activity for adults is only half an hour of 5 or more days a week? (And it's one hour for children). Fortunately you do not need to do the entire thirty minutes of exercise in one session, shorter bouts of activity are apparently equally as effective. This physical exercise is necessary to help promote and maintain a healthy lifestyle.
The really good news is that even moderate physical activity such as brisk walking is beneficial to good health. So, wherever and whenever possible opt for the stairs rather than the lift or the escalator. Park the car a little further from the shops and walk the last bit. If you use the bus, walk to the next stop along, or get off the bus a stop or two sooner. You don't need a dog or a gym to get your exercise - though these are more sociable options.
