Consistent exercise positively influences metabolism over time by increasing muscle mass, which burns more calories at rest than fat tissue. Regular physical activity boosts the resting metabolic rate and improves metabolic efficiency, allowing the body to process nutrients more effectively. Additionally, exercise encourages the body to utilize fat as a primary energy source, particularly during prolonged activities. As individuals incorporate strength training and aerobic exercises into their routines, they build a foundation for long-term metabolic health and weight management.
