Resistance training can significantly improve metabolic rate, which is the rate at which the body expends energy. Building muscle through resistance training helps to increase resting metabolic rate, meaning that individuals burn more calories even while at rest. This occurs because muscle tissue is more metabolically active than fat tissue. Additionally, engaging in high-intensity resistance workouts can lead to increased calorie burn during and post-exercise due to the EPOC effect (excess post-exercise oxygen consumption). Consequently, incorporating resistance training into regular fitness routines is essential for weight management.
