Strength training can significantly improve metabolic rate by increasing muscle mass, which in turn burns more calories at rest compared to fat tissue. When individuals engage in resistance training, they stimulate muscle growth and enhance overall body composition. The afterburn effect, or excess post-exercise oxygen consumption (EPOC), also contributes to additional calorie expenditure after workouts. By incorporating strength training into regular fitness routines, individuals can elevate their metabolic rate, supporting weight management and enhancing overall fitness levels.
