Myth 1. Exercising makes you tired.

As they become more physically fit, most people feel physical activity gives them even more energy than before. Regular, moderate-to-brisk exercise can also help you reduce fatigue and manage stress.

Myth 2. Exercising takes too much time.

It only takes a few minutes a day to become more physically active. To condition your heart and lungs, regular exercise does not have to take more than about 30 to 60 minutes, three or four times a week. If you don't have 30 minutes in your schedule for an exercise break, try to find two 15-minute periods or even three 10-minute periods. Once you discover how much you enjoy these exercise breaks, you may want to make them a habit! Then physical activity becomes a natural part of your life.

Myth 3. All exercises give you the same benefits.

All physical activities can give you enjoyment. Low-intensity activities - if performed daily - also can have some long-term health benefits and lower your risk of heart disease. But only regular, brisk and sustained exercises such as brisk walking, jogging or swimming improve the efficiency of your heart and lungs and burn off substantial extra calories. Other activities may give you other benefits such as increased flexibility or muscle strength, depending on the type of activity.

Myth 4. The older you are, the less exercise you need.

We tend to become less active with age, and therefore need to make sure we are getting enough physical activity. In general, middle-aged and older people benefit from regular physical activity just as young people do. Age need not be a limitation. In fact, regular physical activity in older persons increases their capacity to perform activities of daily living. What is important, no matter what your age, is tailoring the activity program to your own fitness level.
