Is There Such a Thing as Too Much Cardio?

When it comes to heart health, you may want to easy up on the cardio.


Exercise has been proven to boost heart health, but too much cardio may have the reverse effect. A new study published by the American Physiological Society has found that positive health effects of exercise tend to follow a bell curve. In particular, the heart-healthy benefits of exercise increase with intensity and duration to a point. After that point, they plateau or even decline.

While this doesn’t mean you should lay off the intensity of your cardio, it does support the theory that weight training mixed with some cardio tends to be better for you than miles of long-distance running. It also means that you should talk to your doctor if you have a history of family heart disease. If you have an inherited heart abnormality, too much strenuous exercise may exacerbate the condition.
