Regular exercise boosts the metabolic rate by enhancing muscle mass and promoting efficient energy use. Engaging in physical activity increases the number of calories burned both during and after workouts due to the afterburn effect. Strength training, in particular, aids in building muscle, which requires more energy to maintain than fat. Furthermore, regular exercise can improve hormonal balance, aiding metabolic processes. Over time, this consistent activity can lead to a sustained increase in resting metabolic rate, benefiting weight management and overall health.
