Strength training can significantly affect metabolism by increasing muscle mass, which in turn raises the resting metabolic rate (RMR). A higher RMR means the body burns more calories at rest, facilitating weight management and fat loss. Additionally, strength training enhances insulin sensitivity, further supporting metabolic health. The afterburn effect, known as excess post-exercise oxygen consumption (EPOC), allows the body to continue burning calories even after the workout. Consequently, incorporating strength training into regular exercise routines is beneficial for both short-term and long-term metabolic improvement.
