Strength training has long been seen as something you mainly do to build muscle or look good. But a new study adds to a growing body of evidence that shows lifting weights does far more than change how we look. It may help us live longer – even if you don’t spend hours each day in the gym.
The study drew on three long-running US studies that followed nearly 150,000 nurses and other health professionals for up to 30 years. Every couple of years, participants reported how much time they spent on strength training and aerobic exercise such as walking, cycling and swimming. Over the three decades almost 36,000 of them died, which let the researchers track how muscle-strengthening activity related to the risk of dying early.
