Exercise positively impacts metabolism by increasing the rate at which the body burns calories, both during and after physical activity. Engaging in regular aerobic and strength training helps build lean muscle mass, which is metabolically active and increases resting metabolic rate. This means that individuals with more muscle burn more calories even at rest. Exercise also improves insulin sensitivity, aiding in effective energy use and fat metabolism. Additionally, a higher metabolic rate can assist in weight management. Thus, incorporating regular exercise into daily routines is crucial for optimizing metabolic health.
