heart
The heart is the primary organ in the cardiovascular system that benefits significantly from exercise. Regular physical activity strengthens the heart muscle, improves its efficiency in pumping blood, and enhances overall cardiovascular health. Exercise also helps lower resting heart rate and blood pressure, while improving circulation and reducing the risk of heart disease. Overall, consistent exercise contributes to a healthier, more resilient heart.
