If you’ve ever been tempted to skip leg day at the gym, you might want to reconsider — your heart could depend on it. According to renowned cardiovascular surgeon Dr. Jeremy, strong legs are not just about aesthetics or athletic performance; they play a pivotal role in protecting heart health.
“Leg muscles make up nearly 40 to 50 percent of our total muscle mass,” Dr. Jeremy said. “This makes them a crucial area of focus for those aiming to improve overall muscle volume and, by extension, cardiovascular health.”
While many gym-goers dread the intense burn of squats, lunges, and deadlifts, emerging research suggests that these workouts have far-reaching benefits beyond toned thighs and calves. Here’s how working your legs can boost your heart health:
-
Improved Insulin Sensitivity: Increased muscle mass enhances the body’s ability to regulate blood sugar levels, reducing the risk of insulin resistance — a major contributor to heart disease.
-
Better Glucose Control: With greater muscle mass, especially in the lower body, the body can more efficiently process glucose, preventing spikes that strain the heart.
-
Reduced Inflammation: Muscle mass is inversely related to full-body inflammation, which is a major risk factor for both heart attacks and strokes.
-
Stronger Circulatory Support: Leg workouts improve venous return — the flow of blood back to the heart — which can prevent issues like blood clots and varicose veins.
Dr. Jeremy also noted that numerous well-designed studies back the correlation between leg strength and improved cardiovascular outcomes. “Don’t skip leg day,” he warned. “It’s not just about fitness — it’s a long-term investment in your heart’s well-being.”
So, the next time you’re tempted to skip the squat rack, remember: stronger legs could mean a stronger heart.
