we know that lifting weights helps build muscle, but now comes proof that a muscle that also benefits is the heart. a new study published in the journal of the american medical association shows that weightlifting reduces the risk of coronary heart disease. it
does that in a number of ways, such as lowering the bad kind of cholesterol and increasing the good kind. weightlifting also helps reduce body fat and helps the body process sugar leading to a healthier heart.
for a half-hour a day did have a reduced risk for heart disease, but that others who did more intense exercise saw their risk reduced significantly more. "people who don't exercise should start moving. even moderate amounts of walking are beneficial. however, more intense activities are probably going to confer an additional benefit."
