Regular exercise positively influences metabolism as one ages by promoting muscle mass and enhancing metabolic rate. As individuals age, they naturally experience a decline in muscle mass, leading to a slower metabolism. Engaging in consistent strength training and cardiovascular exercise helps counter this effect, allowing older adults to maintain or even increase their metabolic efficiency. Additionally, regular physical activity improves insulin sensitivity and helps regulate blood sugar levels, reducing the risk of metabolic disorders. Therefore, incorporating exercise into daily routines is vital for overall health and metabolic well-being as one ages.
