Cardio exercise plays a vital role in preventing heart disease, the leading cause of death in the U.S. Experts recommend 150 minutes of moderate or 75 minutes of vigorous cardio weekly, combined with strength training, to maintain heart health1. Activities like walking, swimming, and biking are effective ways to elevate heart rate, with faster paces offering greater benefits2. Regular cardio not only reduces plaque buildup and lowers cholesterol but also aids in weight management and promotes longevity3.
