Resistance training contributes to the metabolic rate by increasing muscle mass, which in turn raises the number of calories burned at rest. As individuals engage in resistance exercises, muscle fibers endure micro-tears, leading to repair and growth, a process known as muscle hypertrophy. This increased muscle mass not only enhances strength and endurance but also heightens overall energy expenditure. Furthermore, resistance training can stimulate the post-exercise oxygen consumption (EPOC) effect, where the body continues to burn calories even after the workout has concluded, effectively boosting metabolism.
