Regular exercise is crucial for maintaining a healthy heart. Cardiovascular exercises such as running, swimming, and cycling strengthen the heart muscle, improve blood circulation, and reduce the risk of heart diseases. According to the American Heart Association, adults should aim for at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous activity each week. Incorporating physical activity into your daily routine can also help manage weight, lower blood pressure, and improve cholesterol levels. Always consult with your cardiologist before starting a new exercise regimen, especially if you have existing heart conditions.
