Strength training is essential for metabolism because it increases muscle mass, which in turn raises resting metabolic rate. As muscle tissue is more metabolically active than fat, individuals with higher muscle mass burn more calories at rest, contributing to effective weight management. Additionally, strength training promotes the process of muscle hypertrophy, enhancing physical performance and endurance. It also has positive effects on insulin sensitivity, reducing the risk of metabolic disorders like Type 2 diabetes. Overall, integrating strength training into fitness regimens is vital for long-term metabolic health.
