Meryl Streep, the acclaimed actress known for her role in *The Devil Wears Prada*, has shared her commitment to low-impact swimming as a key component of her fitness routine at 76. This exercise not only helps her maintain her body shape but also offers significant heart health benefits, especially for older adults. Cardiologist Dr. Varun Bansal from Apollo Hospitals in New Delhi explains that low-impact aerobic activities like swimming strengthen the heart and regulate blood pressure without stressing aging joints. Research indicates that consistent moderate exercise, such as swimming, is more effective for cardiovascular health in seniors than high-intensity workouts. Streep aims for 55 laps daily, focusing on health rather than aesthetics, and her routine exemplifies modern heart science recommendations for aging individuals. Experts warn that sudden high-intensity workouts can increase the risk of arrhythmias and injuries, making low-impact exercises a safer choice for maintaining fitness and heart health. Safety measures, such as installing handlebars and anti-slip mats, are crucial for elderly swimmers to prevent falls. Overall, Streep's fitness journey serves as an inspiring model for healthy aging.
