Here's yet another reason to start exercising more often. The latest research from Australia has found that the largest risk factor for heart disease in women after the age of 30 is not getting enough exercise.

Published in the British Journal of Sports Medicine, the study attempted to pinpoint certain risk factors contribute to women’s likelihood of getting heart disease over the course of their lives.

The data was taken from 40,000 participants across 15 age groups (spanning ages 22 to 90). The results revealed that smoking is the most common risk factor for heart disease in young adult women, but those age 30 and above who are "inactive" are most at risk for heart disease.

Based on the results, the researchers advise women in this category to slot in at least 30 to 45 minutes of daily exercise as a way to reduce their risk by half.
