Why Should I Be Physically Active?

Updated:Dec 4,2015

If your doctor has suggested that you begin a physical activity program, follow that advice. The American Heart Association recommends that adults get at least 150 minutes of moderate-intensity physical activity each week. People who don’t get enough physical activity are much more likely to develop health problems.

Regular, moderate-intensity aerobic physical activity can lower your risk of:

  • Heart disease and heart attack
  • High blood pressure
  • High total cholesterol, high LDL (bad) cholesterol and low HDL (good) cholesterol
  • Overweight or obesity
  • Diabetes
  • Stroke

If you have a chronic condition, talk to your health care provider about an exercise program that’s right for you. Once you start, you’ll find that exercise isn’t just good for your health — it’s also fun! 

What else can physical activity do for me?

Physical activity is associated with these benefits:

  • Strengthens your heart, lungs, bones and muscles.
  • Gives you more energy and strength.
  • Favorable body composition
  • Helps control your weight and blood pressure.
  • Helps you handle stress.
  • Helps your quality of sleep .
  • Helps you feel better about how you look.

What kind of activities should I do?

You don’t have to be an athlete to lower your risk of heart disease and stroke! If done on most or all days, you can benefit from moderate activities like these:

  • Brisk walking
  • Gardening and yard work
  • Moderate to heavy housework
  • Pleasure dancing and home exercise

More vigorous physical activity can further improve the fitness of your heart and lungs. Start slowly, and build up as your heart gets stronger. Start with light or moderate intensity, for short periods of time. Spread your sessions throughout the week. 

Most healthy adults do not need to consult a doctor or health-care provider before becoming more physically active. But, healthcare providers can provide advice on the types of activities best for you and ways to progress at a safe and steady pace. Then try one or more of these:

  • Hiking or jogging
  • Stair climbing
  • Bicycling, swimming or rowing
  • Aerobic dancing or cross-country skiing

How often should I exercise?

  • Work up to a total of at least 150 minutes of moderate-intensity physical activity or 75 minutes of vigorous physical activity per week.
  • Make sure it’s regular — you can reach your 150 minute goal by getting about 30 minutes of physical activity on most or all days of the week.

What else can I do?

Look for ways to add more physical activity to your daily routine. Making small changes in your lifestyle can make a big difference in your overall health. Here are some examples:

  • Take a walk for 10 or 15 minutes during your lunch break.
  • Take stairs instead of escalators and elevators.
  • Park farther from the store and walk through the parking lot.
