Coronary Heart Disease (CHD) occurs when an accumulation of plaque (cholesterol deposits) in the arteries block (or almost blocking) the blood flowing to and from the heart.

More than 600,000 people die of Heart Disease each year. CHD is the leading cause of death for men and women in the United States according to the Center for Disease Control.

A study published in The Journal Circulation found that people who follow the Federal Guideline for exercise reduced their risk by 14% of getting CHD in comparison to those who did not exercise. The Federal Guideline for exercising standard entails 150 minutes spread out across 5 day, 30 min., moderate intensity workouts per week.

"The overall findings of the study corroborate federal guidelines - even a little bit of exercise is good, but more is better – 150 minutes of exercise per week is beneficial, 300 minutes per week will give even more benefits," said Jacob Sattelmair, ScD, of the Department of Epidemiology at the Harvard School of Public Health.

"Early studies broke people into groups such as active and sedentary. More recent studies have begun to assess the actual amount of physical activity people are getting and how that relates to their risk of heart disease." said Statelmair.
