Regular weight training positively impacts metabolism by boosting the body’s resting metabolic rate (RMR). Engaging in consistent strength training not only builds muscle mass but also increases the amount of energy required for the body to maintain that mass. Muscle tissue burns more calories at rest compared to fat tissue, thereby enhancing overall caloric expenditure. Furthermore, post-exercise, the body continues to consume calories as it recovers, known as the afterburn effect. This mechanism contributes to weight management and improved metabolic health.
