Fitness: Getting and Staying Active

Why Should You Be More Active?

No matter what your size or shape, being active:

• Makes you feel better.
• Helps you fall asleep and sleep well.
• Gives you more energy.
• Helps you think better and faster.
• Helps you handle stress.
• Makes you healthier.
• Helps you live longer.

Fitness benefits everyone. Learn about fitness in children and teens, in older adults, and during pregnancy.

Your health will thank you

The more active you are, the better your heart and lungs work. You're less likely to get many of the diseases that can shorten your life, including:

• Coronary artery disease.
• High blood pressure.
• Type 2 diabetes.
• Some cancers.

If you already have any of these problems, staying active may help you to have better control over them, feel better, and live longer.

Your body will thank you

Being fit includes keeping your muscles, bones, and joints as active and healthy as possible. You can:

• Make your muscles stronger. Lifting weights—even small ones—is a good way to do this. Weights also increase bone density, which is especially important for older adults.^{footnote 1}
• Stay flexible and coordinated. Stretching will help you do this. As you become more flexible, you will find it easier to reach things on high shelves, look under a bed, or perhaps tie your shoes. You will also have a better sense of balance and coordination.

Your bathroom scale will thank you

Being more active burns calories. That can help you get to and stay at a healthy weight. Getting regular exercise:

• Helps your body burn more calories even when you're resting.
• May lower your percentage of body fat and increase muscle strength and tone.

You'll thank yourself

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?

You can be active by doing housework, mowing the lawn, walking, or joining a fitness class. It's important to be active in three areas: aerobic activity, muscle strength, and stretching.

Aerobic activity

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:^{footnote 2}

• Get moderate aerobic activity for at least 2½ hours a week.
• Get vigorous aerobic activity for at least 1¼ hours a week.

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:

• If you can't talk and do your activity at the same time, you are exercising too hard.
• If you can sing while you do your activity, you may not be working hard enough.
• If you can talk but can't sing while you do your activity, you are doing fine.

Another way to see how hard you exercise is to find your target heart rate. As a guideline, use the Interactive Tool: What Is Your Target Heart Rate? and learn to take your pulse.

Stronger muscles

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:

• Resistance training. This helps build muscles through regular use, especially when your muscles have to work against something.
• Strengthening your core. This helps build the muscles around your belly and back (trunk). This is called core stability. It can help you have better posture and balance, and help protect you from injury.
  • Fitness: Increasing Core Stability

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 resistance-training exercises include lifting weights, doing push-ups, or using elastic bands.

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:

• What challenges get in my way? You may have barriers in your life that get in the way of becoming more active. These barriers may be a lack of time, fear of getting hurt, or having no one to exercise with.
• Is physical activity safe for me? For some people, some forms of physical activity might be unsafe. If you have heart disease, high blood pressure, diabetes, or any health concerns, talk to your doctor before you start any exercise or fitness program. Your doctor may want to help you build an exercise plan matched to your needs. You can find a way to be active safely.

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:

• Don't compare yourself to others. Healthy bodies come in all shapes, sizes, and ages. One person's choice of activity won't be right for another person. Some people use fitness to compete against others, while others use it to feel as good as possible.
• Think positive. You can help yourself succeed just by thinking that you can succeed. If you tell yourself negative things—"I can't do this. Why bother?"—change will be harder. But if you encourage yourself with thoughts like "I can do this," you can raise your odds of success.

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:

1. Have your own reason for making a change. Know why it's important to you to meet your goals.
2. Set goals. Include both long-term and short-term goals.
3. Think about what might get in your way, and prepare for slip-ups.
4. Get support from your family, your doctor, your friends—and from yourself.
5. Measure improvements to your health. For example, keep track of your blood pressure, cholesterol, or blood sugar.

Staying Active

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.

It might take a long time for you to form a habit. 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.

• Fitness: Making It a Habit

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:

• Set goals. Develop and follow a specific program.
• Make it a habit. Turn physical activity into a normal, pleasant, and routine part of your life.
• Get the support of friends and family.
• Expand your fitness activities through coaching, competition, and cross-training.
• Add variety to your fitness program. Change the place, activity, and time.
• Don't let reasons such as lack of time or bad weather slow you down.
• Schedule your activity for times that you're likely to keep doing it. If you don't have time for one 30-minute walk, break it up into three 10-minute walks.

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.

Structured fitness

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:

• Being held at the same time and place, which may be easier for some people to schedule.
• Having a social atmosphere.
• Providing support and "healthy" peer pressure to show up and participate.
• Sometimes being led by a certified fitness professional.

Self-directed fitness

Many people find an activity they enjoy, and then they create their own fitness program. Self-directed fitness gives you:

• Flexibility as to the time and place.
• The ability to try different types of exercises.

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:

• Daily aerobic activity, such as raking leaves, mowing the lawn, or doing housework.
  • Fitness: Using a Pedometer or Step Counter
  • Fitness: Walking for Wellness
  • Quick Tips: Fitting Physical Activity Into Your Day
• Muscle-building exercises, such as scrubbing the bathtub, washing walls, tilling the garden, or pulling weeds.
  • Quick Tips: Getting Active at Home
• An outdoor interest or hobby that promotes walking or another type of exercise. For example, bird watching may require a lot of walking, and trail building may require both walking and strength to clear paths.

  • Quick Tips: Staying Active in Hot Weather

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:

Overcoming barriers

Barriers	Solutions
"I might be too busy."	My backup plan will be to break my usual 30-minute walk into two 15-minute walks or three 10-minute walks. I will set a time to meet my friend or neighbor every day for a walk.
"I might get bored."	I'll listen to music or podcasts while I walk. I'll get my neighbor to walk with me.
"It might rain."	I'll buy a good rain jacket. My backup plan will be to use an exercise DVD or a treadmill in front of my TV when the weather's bad.

Use a personal action plan to write down your barriers and backup plans.

Can You Be Physically Active 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:

• Start safely. Talk to your doctor before you start, and don't overdo it.
• Keep the benefits in mind. Activity and exercise can strengthen your heart and give you more energy, make falls less likely, and help you sleep at night. It can improve blood pressure and cholesterol.
• Know when to stop. Stop your activity if you are panting or are very short of breath or have pain in your chest. If you think you might be having a heart attack, call 911 right away. Symptoms include pain, pressure, or a strange feeling in your chest, back, neck, jaw, or upper belly, or in one or both shoulders or arms.

Preventing Injury and Illness

Physical activity is good for your health, but you can hurt yourself if you don't do it right. Always keep safety in mind.

• Learn about the risks of any new activity you begin. Take lessons if you need to know how to do exercises with proper form and technique to avoid injury.
• Wear clothing that is right for your activity and the weather. Wear shoes that have good support for your feet.
• Always use the safety gear that goes with your chosen activity, like helmets and knee pads. Learn about the proper fit of that gear.
• Start each activity session slowly. Then work up to your normal level.
• Pay attention to pain and tiredness. They are your body's way of telling you to slow down. Muscle soreness is common when you try a new activity, but pain can mean you're injured. If you are very tired, you may be doing too much too soon.

Watch out for these injuries and illnesses as you exercise:

• Overuse injuries can happen when you use a certain joint over and over without giving it time to recover. Tennis elbow is an example of an overuse injury.
• Dehydration . You can lose too much water through sweating if you don't replace it by drinking fluids as you exercise. Follow these guidelines to avoid dehydration when you exercise.
• Heat exhaustion , heatstroke, or dehydration may be caused by exercising in heat and humidity.
  • Quick Tips: Staying Active in Hot Weather
• Overhydration during exercise is rare. But it is a medical emergency when it happens. When you do strenuous exercise for a long time, such as distance running, you lose water. You can also lose electrolytes, which are minerals your body needs. If you drink lots of water but you don't replace the electrolytes, you can become overhydrated. Symptoms include:
  • Feeling bloated (your watchband may feel tight).
  • Feeling sick to your stomach.
  • Feeling confused.
• Exercise-induced asthma can occur even if you don't have asthma at any other time.
• Overtraining is rare, but it can make you tired and grouchy, as well as raising your risk for injury and illness.
• Heart attack is rare, but be aware of the symptoms. They include pain, pressure, or a strange feeling in your chest, back, neck, jaw, or upper belly, or in one or both shoulders or arms.
