Aerobic exercise pumps oxygenated blood from the heart to working muscles. To accomplish that, it stimulates the heart and breathing rates throughout your exercise session. As a rule aerobic exercise can be light-to-medium intensity activities that can be performed for extended periods of time, such as walking, jogging or biking. Whatever your age, weight or athletic ability, aerobic activity is a health booster that gains efficiency as your body adapts and gets stronger and fitter!
Keeping your cholesterol in check is critical to staying healthy and avoiding heart disease. Two recent studies followed almost two thousand patients with heart disease whose LDL levels -- the bad cholesterol -- was 100 or less.
According to the American Heart Association, ninety-eight million adults over the age of 20 in the United States have high low-density lipoprotein (LDL) --the “bad,” cholesterol, while thirty-one million have total cholesterol levels over 240. Some cholesterol is necessary. The body uses cholesterol to produce estrogen, testosterone, vitamin D, and other vital compounds. However, too much cholesterol, in particularly LDL cholesterol creates dangerous health risks. As a rule, lower LDL and higher HDL cholesterol levels lower the risks of heart disease and other chronic conditions.
