- 2 hours and 30 minutes of moderate-intensity aerobic physical activity or
- 1 hour and 15 minutes of vigorous-intensity aerobic physical activity or
- A combination of moderate and vigorous-intensity aerobic physical activity and
- Muscle-strengthening activities on 2 or more days
- If you're not active at all or have a health problem, start your program with short sessions (5 to 10 minutes) of physical activity and build up to your goal. (Be sure to ask a doctor before you start if you have a health problem.)
- Use safety equipment such as a helmet for bike riding or supportive shoes for walking or jogging.
- Start every workout with a warm-up. If you plan to walk at a brisk pace, start by walking at an easy pace for 5 to 10 minutes. When you're done working out, do the same thing until your heart rate returns to normal.
- Drink plenty of fluids when you are physically active, even if you are not thirsty.
- Use sunscreen when you are outside.
- Always bend forward from the hips, not the waist. If you keep your back straight, you're probably bending the right way. If your back "humps," that's probably wrong.
- Stop your activity if you feel very out of breath, dizzy, nauseous, or have pain. If you feel tightness or pain in your chest, or you feel faint or have trouble breathing, stop the activity right away and talk to your doctor.
- If you can't set aside one block of time, do short activities throughout the day, such as three 10-minute walks.
- Create opportunities for activity. Try parking your car farther away from where you are headed. If you ride the bus or train, get off one or two stops early and walk.
- Walk or bike to work or to the store.
- Use stairs instead of the elevator or escalator.
- Take breaks at work to stretch or take quick walks, or do something active with coworkers at lunch.
- Walk while you talk, if you're using a cellphone or cordless phone.
- Doing yard work or household chores counts as physical activity. Turn on some upbeat music to help you do chores faster and speed up your heart rate.
- Choose activities that you enjoy.
- Vary your activities, so you don't get bored. For instance, use different jogging, walking, or biking paths. Or bike one day, and jog the next.
- Reward yourself when you achieve your weekly goals. For instance, reward yourself by going to a movie.
- If you have children, make time to play with them outside. Set a good example!
- Plan active vacations that will keep you moving, such as taking tours and sightseeing on foot.
- Join a hiking or running club.
- Go dancing with your partner or friends.
- Turn activities into social occasions — for example, go to a movie after you and a friend work out.
- Don't let cold weather keep you on the couch. You can find activities to do in the winter, such as indoor fitness classes or exercising to a workout video.
- If you live in a neighborhood where it is unsafe to be active outdoors, contact your local recreational center or church to see if they have indoor activity programs that you can join. You can also find ways to be active at home. For instance, you can do push-ups or lift hand weights. If you don't have hand weights, you can use canned foods or bottles filled with water or sand.

Studied show that an active lifestyle can lower your risk of early death from a variety of causes. For older adults, activity can improve mental function.Expand all|Collapse all
How can physical activity improve my health?
The 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:
What is body mass index?
You can get an idea of whether you are obese, overweight, or of normal weight by figuring out your body mass index (BMI). BMI is a number calculated from your weight and height. Women with a BMI of 25 to 29.9 are considered overweight. Women with a BMI of 30 or more are considered obese. All adults (aged 18 years or older) with a BMI of 25 or higher are considered at risk for serious health problems. These health risks increase as your BMI rises. Your doctor or nurse can help you figure out your BMI, or you can use this online BMI calculator from the Centers for Disease Control and Prevention (CDC).
How much physical activity should I do?
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.
How much physical activity do I need to do to lose weight?
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.
Does the type of physical activity I choose matter?
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.
How can I prevent injuries when I work out?
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.
Can I stay active if I have a disability?
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.
What are some tips to help me get moving?
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.
Do I need to talk to my doctor before I start?
You should talk to your doctor before you begin any physical activity program if you:
