Couch Potatoes, Sit At Your Own Risk
We've all made the excuses … you can't face the drive to the gym, you're too tired at night, getting up in the morning is a chore or it's too hot or cold outside. So you cozy up on the couch in front of the television. If you're a couch potato, you're a gambler - with your life.
Unfortunately, you'll need a big sofa because you're not the only one whose heart isn't in physical activity. About 60 percent of adults in the U.S. are not getting the exercise they need, according to a
report from the U.S. Surgeon General.
It's time to get up and face … or better yet, dance to ... the music! Here are a few facts that may get you moving for your heart's sake.

Heart-Health Benefits of an Active Lifestyle
Still not convinced? Here are a few facts that describe the heart-health benefits of an active lifestyle.
- By walking 30 minutes each day,
you increase your life expectancy.
- More than half of the participants in a study who jogged two miles a day were able to
stop taking blood pressure medication.
- Taking a brisk one hour walk, five days a week, can
cut your risk for stroke in half.
- People with an active lifestyle have a
45 percent lower risk of developing heart disease than sedentary people.
How Little Exercise is Enough?
So you've decided to get up and get moving. Now what?
Relax. Going from flab to fit doesn't have to take lots of time and effort. You don't need to join a gym, work out for hours or hire a fitness coach.
Moderate Exercise for Just 30 Minutes, Five Days a Week
To stay heart-healthy and fit, the American Heart Association recommends
moderate exercise for just 30 minutes, five days a week. If 30 minutes of exercise is daunting,
breaking it up into two or three 10-15 minute sessions is better than nothing.
"Any activity that gets you up and moving is good," says
Dr. Ernest Gervino, director of the
Clinical Physiology Lab at the
CardioVascular Institute at Beth Israel Deaconess Medical Center. "It's best to exercise at a pace that feels comfortable, and let that be your guide. You don't have to work out at a high-intensity level - in fact, for those who have been sedentary, complications or injury may occur if you move too fast to soon."
Dr. Gervino is a bit skeptical of frequently-issued assurances that exercise in several small increments is just as good as one longer session. Healthy individuals should work a bit harder during short time spurts to make them count, he says.
"If you're working out at a
slower pace, increase frequency to seven days a week," Dr. Gervino advises. "If you are pushing yourself a
faster pace, the frequency can be reduced to three days a week."
Tips to Get You Started
Here are some tips to ensure that you're working out at a pace that's beneficial, yet safe.
Avoid activities that make you grunt or strain. This type of strain occurs when you bear down and momentarily stop breathing to lift weights or do sit-ups or push-ups, etc., and may be harmful, particularly if you have had heart surgery in the past.
- A good rule of thumb is to increase your activity so you
breathe hard but can still carry on a conversation. If you feel your heart beating but can speak at length, you are working out at a safe level of activity.
- If you're not used to exercising,
don't do too much too soon. Start with 10 minutes of light exercise or a brisk walk every day and gradually increase duration and intensity of your activities.
Be alert for signs of physical distress, such as discomfort in your arm, back, neck, jaw or chest or severe shortness of breath lasting more than five minutes. (Contact medical help or 911 immediately if you are concerned.)
If you have a chronic health condition such as
other health conditions, be sure to talk with your doctor about the physical activity that is best for you.

How Exercise Benefits Your Heart
Reverses Some Heart Disease Risk Factors
"Exercise improves heart health and can even
reverse some heart disease risk factors," said Dr. Gervino. "The heart, like all muscles, becomes stronger as a result of exercise, which allows it to pump more blood through the body with each beat. This allows the heart to work effectively while beating slower."
Lowers Blood Pressure and Cholesterol Levels
Being active also promotes vigorous blood circulation, which
keeps blood vessels open and flexible. Regular exercise reduces inflammation in the arteries and can
lower blood pressure and cholesterol levels (LDL).
Helps Prevent Diabetes
Cardiac fitness also
improves glucose tolerance and insulin sensitivity. This
helps to prevent
diabetes, which is a major cause of blood vessel damage and vascular complications that can lead to heart attack,
peripheral artery disease.
Peel Yourself Off the Couch
"Unfortunately, it sometimes takes a catastrophic event, such as a heart attack, to motivate a person to change their lifestyle," said Dr. Gervino. "It's best to
pay attention to blood test results, current weight and energy levels - be alert to signs that your body is not at its best so you can take action before you get a medical wake-up call."
The facts are clear.
Regular physical activity enables your heart and your body to function at their best. So get up and
go for a walk. C'mon, you can do it. The first step to a healthier you is exactly that … taking a step.
