Fitness: Getting and Staying Active
What is fitness?
Fitness means being able to perform physical activity. It also means having the energy and strength to feel as good as possible. Getting more fit, even a little bit, can improve your health.
You don't have to be an athlete to be fit. A brisk half-hour walk every day can help you reach a good level of fitness. And if this is hard for you, you can work toward a level of fitness that helps you feel better and have more energy.
What are the benefits of fitness?
Fitness helps you feel better and have more energy for work and leisure time. You'll feel more able to do things like playing with your kids, gardening, dancing, or biking. Children and teens who are fit may have more energy and better focus at school.
When you stay active and fit, you burn more calories, even when you're at rest. Being fit lets you do more physical activity. And it lets you exercise harder without as much work. It can also help you manage your weight.
Improving your fitness is good for your heart, lungs, bones, muscles, and joints. And it lowers your risk for falls, heart attack, diabetes, high blood pressure, and some cancers. If you already have one or more of these problems, getting more fit may help you control other health problems and make you feel better.
Being more fit also can help you to sleep better, handle stress better, and keep your mind sharp.
How much physical activity do you need for health-related fitness?
Experts say your goal should be one, or a combination, of these:
Children need more activity. Encourage your child (age 6 to 17) to do moderate to vigorous activity at least 1 hour every day.
Here's an easy way to tell if your exercise is moderate: If you can't talk while you're doing the activity, you're working too hard. You're at a moderate level of activity if you can talk but not sing during the activity.
What types of physical activity improve fitness?
The activities you choose depend on which kind of fitness you want to improve. There are three different kinds of fitness:
How can you be more physically active?
Moderate physical activity is safe for most people. But it's always a good idea to talk to your doctor before becoming more active, especially if you haven't been very active or have health problems.
If you're ready to add more physical activity to your life, here are some tips to get you started:

The best thing about being active and fit is a better quality of life. You're able to do things you enjoy for longer periods of time, like playing with children, gardening, dancing, or walking.
What Does "Being Active" Really Mean?
Being active means allowing your body to "practice" breathing, using your muscles, and stretching. The more practice your body gets, the better it works.
It's important to be active in three areas: aerobic activity, muscle strength, and stretching.
Aerobic activity makes your heart and lungs work harder and builds up your endurance. It gets more oxygen to your muscles, which allows your muscles to work longer. Aerobic activities include walking, running, cycling, and swimming.
To get and stay healthy, experts say to do either of these: 2
You can choose to do one or both types of activity. And it's fine to be active in several blocks of 10 minutes or more throughout your day and week. Do what works best for you. For example, you could do moderate activity for 45 minutes every other day. Or you could do 10 minutes 3 times a day, 5 days a week.
How hard to work
Moderate activity causes your heart and lungs to work harder. Here's an easy way to know if you're working hard enough to get the health benefits of moderate-level activity:
Building stronger muscles is an important part of overall health. When your muscles are strong, you can carry heavy grocery bags more easily, pick up children without feeling as much strain, or do more downhill ski runs before you get too tired and have to stop.
Making your muscles stronger includes:
Experts advise people to do exercises to strengthen muscles at least 2 times a week. Be sure to work the major muscle groups: legs, hips, back, abdomen, chest, shoulders, and arms.
Examples of exercises that strengthen muscles include lifting weights and resistance training.
Stretching for flexibility
Flexibility means being able to move your joints and muscles through their full range of motion.
As you become more flexible, you will find it easier to reach things on high shelves, to look under a bed, or perhaps to tie your shoes. You will also have a better sense of balance and coordination.
To stay flexible, stretch all your major groups of muscles. These include the muscles of your arms, your back, your hips, the front and back of your thighs, and your calves.
As you get started with flexibility and stretching, begin slowly, and increase your efforts bit by bit. You can measure your progress with flexibility by noticing how much farther you can do each stretch. Can you stretch farther each day than you could when you started? If so, your flexibility is getting better.
Do your stretching and flexibility exercises in addition to your aerobic and strength-building exercises.
Becoming More Active
Are you ready?
Before you increase your activity, take a look at where you are now. Ask yourself these questions:
Changing your thinking
If you need to make some lifestyle changes to become more active, you'll have more success if you first change the way you think about certain things:
Changing your habits
Making any kind of change in the way you live your daily life is like being on a path. The path leads to success. Here are steps you can use to change a habit by setting goals:
Turning physical activity into a habit
Most people don't think about being active or inactive as a habit. But it is. And habits are affected by many things, including our work schedule, our home life, and our social life. When something becomes a habit, we don't think about it much—we just do it, like brushing our teeth.
The key to staying active is to make fitness a habit—something that you just do.
Experts say it takes about 3 months of repetition to form a habit. For some people, even 3 months isn't enough. So start small, and keep doing an activity until you no longer think about it as something "extra" that you have to do.
When you slip up, don't get mad at yourself or feel guilty. Figure out what happened and how to keep it from happening again. Get right back into your physical activity routine, and don't look back.
Maintaining the lifestyle
Many of the good things about being active, such as having more energy and being in a better mood, happen soon after you become more active. But some of the most important health benefits have to do with being active over many years. If you stop being active, you lose the fitness you achieved. Being consistent makes the most sense for your health.
To help make physical activity a long-term commitment:
Finding what works for you
When you have decided that you want to get fit, you will want to plan a physical activity routine. Although most people think of classes and specific activities (such as jogging or tennis) as the way to fitness, there are many ways you can work physical activity into your life.
Fitness classes or groups provide a consistent approach to an activity. Local gyms, schools, and churches may sponsor a regular fitness group. Teams also provide a consistent approach to fitness but are more competitive. Many communities have physical activity programs to help adults and children get fit. They often are found within social agencies and schools.
Structured fitness has the advantage of:
Many people find an activity they enjoy, and then they create their own fitness program. Self-directed fitness gives you:
For this to be effective, you must set up a regular schedule and stay with it.
Fitness within your day
You can use "everyday" activities for fitness, as long as you do them regularly. This includes:
Preparing for slip-ups
It's perfectly normal to try to change a habit, go along fine for a while, and then have a setback. Lots of people try and try again before they reach their goals.
What are the things that might cause a setback for you? If you have tried to make changes in your activity level before, think about what helped you and what got in your way.
By thinking about these barriers now, you can plan ahead for how to deal with them if they happen.
Here's one person's list of barriers to taking a brisk 30-minute walk every day, along with some possible solutions:
Physical Activity As You Get Older
It's never too late to start getting active. You can benefit from physical activity even if you think of yourself as "elderly" or you already have conditions such as arthritis or heart disease. Being more active will help you feel better and may even help you live longer.
If you haven't been active for a long time, you may have no idea where to start. The important thing is to take that first step—and make that first step a small one.
If you're an older adult and are starting activity, be sure to:
