The new 2008 Physical Activity Guidelines for Americans state that an active lifestyle can lower your risk of early death from a variety of causes. There is strong evidence that regular physical activity can also lower your risk of:
Regular activity can help prevent unhealthy weight gain and also help with weight loss, when combined with lower calorie intake. If you are overweight or obese, losing weight can lower your risk for many diseases. Being overweight or obese increases your risk of heart disease, high blood pressure, stroke, type 2 diabetes, breathing problems, osteoarthritis, gallbladder disease, sleep apnea (breathing problems while sleeping), and some cancers.
Regular physical activity can also improve your cardiorespiratory (heart, lungs, and blood vessels) and muscular fitness. For older adults, activity can improve mental function.
Physical activity may also help:
Health benefits are gained by doing the following each week:
This physical activity should be in addition to your routine activities of daily living, such as cleaning or spending a few minutes walking from the parking lot to your office.
During moderate-intensity activities you should notice an increase in your heart rate, but you should still be able to talk comfortably. An example of a moderate-intensity activity is walking on a level surface at a brisk pace (about 3 to 4 miles per hour). Other examples include ballroom dancing, leisurely bicycling, moderate housework, and waiting tables.
If your heart rate increases a lot and you are breathing so hard that it is difficult to carry on a conversation, you are probably doing vigorous-intensity activity. Examples of vigorous-intensity activities include jogging, bicycling fast or uphill, singles tennis, and pushing a hand mower.
If you want to lose a substantial (more than 5 percent of body weight) amount of weight, you need a high amount of physical activity unless you also lower calorie intake. This is also the case if you are trying to keep the weight off. Many people need to do more than 300 minutes of moderate-intensity activity a week to meet weight-control goals.
Yes! Engaging in different types of physical activity is important to overall physical fitness. Your fitness routine should include aerobic and strength-training activities, and may also include stretching activities.
These activities move large muscles in your arms, legs, and hips over and over again. Examples include walking, jogging, bicycling, swimming, and tennis.
These activities increase the strength and endurance of your muscles. Examples of strength-training activities include working out with weight machines, free weights, and resistance bands. (A resistance band looks like a giant rubber band. You can buy one at a sporting goods store.) Push-ups and sit-ups are examples of strength-training activities you can do without any equipment. You also can use soup cans to work out your arms.
Aim to do strength-training activities at least twice a week. In each strength-training session, you should do 8 to 10 different activities using the different muscle groups throughout your body, such as the muscles in your abdomen, chest, arms, and legs. Repeat each activity 8 to 12 times, using a weight or resistance that will make you feel tired. When you do strength-training activities, slowly increase the amount of weight or resistance that you use. Also, allow one day in between sessions to avoid excess strain on your muscles and joints.
Stretching improves flexibility, allowing you to move more easily. This will make it easier for you to reach down to tie your shoes or look over your shoulder when you back the car out of your driveway. You should do stretching activities after your muscles are warmed up — for example, after strength training. Stretching your muscles before they are warmed up may cause injury.
Being physically active is safe if you are careful. Take these steps to prevent injury:
Exercise should not hurt or make you feel really tired. You might feel some soreness, a little discomfort, or a bit weary. But you should not feel pain. In fact, in many ways, being active will probably make you feel better.
A disability may make it harder to stay active, but it shouldn't stop you. In most cases, people with disabilities can improve their flexibility, mobility, and coordination by becoming physically active. Getting regular physical activity can also help you stay independent by preventing illnesses, such as heart disease, that can make caring for yourself more difficult.
Even though you have a disability, you should still aim to meet the physical activity goals listed in How much physical activity should I do? Work with a doctor to develop a physical activity plan that works for you.
Fit it into a busy schedule
Make it fun
Make it social
Don't expect to notice body changes right away. It can take weeks or months before you notice some of the changes from being physically active, such as weight loss. And keep in mind, many benefits of physical activity are happening inside you and you cannot see them.
You should talk to your doctor before you begin any physical activity program if you:
