A recent study found that people who did strength training for just one hour a week had a lower risk of heart attack, stroke, and death from heart disease compared with people who didn't do any. The two main factors that seemed to mediate this benefit were stronger quadriceps muscles (the muscles in the fronts of the thighs) and a decrease in body mass index. The study was published in March 2019 in Medicine & Science in Sports & Exercise. Stronger muscles help your body pull oxygen and nutrients from the bloodstream more efficiently, lightening the load on your heart. And when you boost your muscle mass, you burn more calories, both during and after exercise.
