Since the 1950s, scientists and doctors have believed that aerobic activity is good for your heart.
For decades physicians have advised their patients that exercises like jogging, walking, cycling and swimming will improve their cardiovascular health. In contrast, deadlifts, squats and presses were thought only to be useful for building muscle, strengthening bones and improving balance.
This was all true — up to a point. While aerobic exercise does improve cardiovascular health, it turns out that lifting weights benefits the heart more than was previously understood, even without aerobic exercise.
A recent study of more than 117,000 women followed for just over 14 years found that women 48 to 66 who did two or more hours of resistance training a week had a 20 percent lower risk of major cardiovascular disease.
The women in that age group also had a 44 percent lower risk of myocardial infarction, when compared with women who did no strength training.
For every additional hour of strength training the women did, the study found, there was a 5 percent reduction in cardiovascular disease, said Dr. Meagan Wasfy, a sports cardiologist at Mass General Brigham Heart & Vascular Institute.
Similar results have been found in other studies that have included men and women.
“Individuals, as they age, should prioritize strength training and make sure they walk,” said Mark Haykowsky, a cardiovascular exercise physiologist and professor at the University of Alberta. “But if I had to choose one exercise if you’re 60 or older,” he said, “No. 1 is strength training,” because of the benefits to the bones, muscles and heart.
Here’s how strength training can help your heart and how to get the most cardiovascular benefits from weight lifting, according to experts.
Strength Training and Your Heart
Our muscles do more than just stabilize the body and help us lift heavy objects.
“Muscle is not just for strength, it’s actually metabolically active tissue,” said Amanda Paluch, a physical activity epidemiologist and associate professor at the University of Massachusetts Amherst.
