Fitness recommendations; Exercise - physical activity

Physical activity -- which includes an active lifestyle and routine exercise -- plus eating well, is the best way to stay healthy.

An effective exercise program needs to be fun and keep you motivated. It helps to have a goal.

Your goal might be to:

  • Manage a health condition
  • Reduce stress
  • Improve your stamina
  • Buy clothes in a smaller size

Your exercise program can also be a good way for you to socialize. Taking exercise classes or exercising with a friend are both good ways to be social.

You may have a hard time starting an exercise routine, but once you do start, you may begin to notice other benefits, such as:

  • Better control of your weight and appetite
  • Improved fitness, making it easier to do everyday activities
  • Improved sleep
  • More confidence in yourself
  • Lower risk for heart disease, diabetes, and high blood pressure

GETTING STARTED

You do not need to join a gym to exercise. If you have not exercised or been active in a long time, start slowly to prevent injuries. Taking a brisk 10-minute walk twice a week is a good start.

Try joining a dance, yoga, or karate class if it appeals to you. You could also join a baseball or bowling team, or even a mall-walking group. The social aspects of these groups can be rewarding and motivating.

The most important thing is to do exercises that you can maintain and enjoy.

IMPORTANT NOTE: Talk with your health care provider before starting an exercise program if:

  • You have diabetes, heart disease, lung disease, or another long-term illness
  • You are obese
  • You have not been very active lately
  • You get chest pains or shortness of breath when you are active

Build physical activity into your regular routine

Simple lifestyle changes can make a big difference over time.

  • At work, try taking the stairs instead of the elevator, walking down the hall to talk with a co-worker instead of sending an email, or adding a 10- to 20-minute walk during lunch.
  • When you are running errands, try parking at the far end of the parking lot or down the street. Even better, walk to the store or other nearby places.
  • At home, do chores such as vacuuming, washing the car, gardening, raking leaves, or shoveling snow.
  • If you ride the bus or other public transportation, get off 1 stop before your usual stop and walk the rest of the way.

REDUCE YOUR SCREEN TIME

Sedentary behaviors are things you do while you are sitting still. Decreasing your sedentary behaviors can help you lose weight. For most people, the best way to decrease sedentary behaviors is to reduce the time they spend watching TV and using a computer and other electronic devices. All of these activities are called "screen time."

Some ways to decrease screen time are:

  • Choose 1 or 2 TV programs to watch, and turn off the TV when they are over.
  • Do not keep the TV on all the time for background noise -- you might end up sitting down and watching it. Turn on the radio instead. You can be up doing things around the house and still listen to the radio.
  • Do not eat while you watch TV.
  • Take the batteries out of your TV remote control and get up to change the channel.
  • Before you turn on the TV, take your dog or a neighbor's dog for a walk. If you are going to miss your favorite show, record it.
  • Find activities to replace TV watching. Read a book, play a board game with family or friends, or take an evening cooking class.
  • Work out on an exercise or yoga ball while you watch TV. You will burn calories. Or, set up a stationary bike or treadmill in front of your TV and use it while you watch.

If you like playing video games, try games that require you to move your whole body, not just your thumbs.

HOW MUCH EXERCISE DO YOU NEED?

Aim to exercise about 2.5 hours a week. It's important to do both moderate-intensity aerobic activity that increases your heart rate and muscle strengthening. Muscle strengthening, also called strength training, resistance training, or endurance exercise, should be done 2 times a week. Depending on your schedule, you could exercise for 30 minutes 5 days a week, or 45 to 60 minutes 3 days a week.

You do not have to do your total daily exercise all at once. If your goal is to exercise for 30 minutes, you can break that up into shorter time periods that add up to 30 minutes.

As you become more fit, you can challenge yourself by increasing the intensity of your exercise by going from light to moderate activity. You can also increase the amount of time you exercise.

Exercise can lower blood pressure

Reducing your weight by just 10 pounds may be enough to lower your blood pressure. Losing weight can help to enhance the effects of high blood pressure medicine and may also reduce other risk factors, such as diabetes and high bad cholesterol.

Aerobic exercise

Aerobic exercise gets the heart working to pump blood through the heart more quickly and with more force than normal. As blood is pumped faster, it must be oxygenated more quickly, which quickens respiration. Aerobic exercise strengthens the heart and boosts healthy cholesterol levels. Low impact aerobics include walking and swimming. Running, tennis and dance are high impact aerobics.

Benefit of regular exercise

Physical activity contributes to health by reducing the heart rate, decreasing the risk for cardiovascular disease, and reducing the amount of bone loss that is associated with age and osteoporosis. Physical activity also helps the body use calories more efficiently, thereby helping in weight loss and maintenance. It can also increase basal metabolic rate, reduces appetite, and helps in the reduction of body fat.

Flexibility exercise

Flexibility exercise in its simplest form stretches and elongates muscles. Disciplines which incorporate stretching with breath control and meditation include yoga and t'ai chi. The benefits of greater flexibility may go beyond the physical to the improvement of stress reduction and the promotion of a greater sense of well-being.

Isometric exercise

Isometric exercise works muscles and strengthens bone. Increased muscle mass elevates metabolism, which in turn burns fat. Strength training is also called anaerobic exercise, as opposed to aerobic, because increased oxygen production is not required.

Exercise and age

Exercise can help older people feel better and enjoy life more, even those who think they are too old or too out of shape.

Exercise with friends

Exercising with a friend or a group of people can help make it more fun, interesting, and keep you motivated to continue with a regular exercise routine.

Exercise - a powerful tool

Physical fitness is essential to good health and is one of the best things you can do for your body, mind, and spirit. Exercise improves the way your body works, and it can make you look better, feel better, and even live longer.

Preventive medicine

Physical activity contributes to health by reducing the heart rate, decreasing the risk for cardiovascular disease, and reducing the amount of bone loss that is associated with age and osteoporosis. Physical activity also helps the body use calories more efficiently, thereby helping in weight loss and maintenance. It can increase basal metabolic rate, reduces appetite, and helps in the reduction of body fat.

Exercise and heart rate

To determine your maximum heart rate, subtract your age from 220. This number represents how many times your heart should beat per minute at its maximum rate. Multiply that number by 0.6 to 0.85 to determine the range of heart rate to strive for. Healthy people can build up gradually to be able to sustain this heart rate for 30 to 45 minutes at least 3 times a week to build aerobic fitness
