How does resistance training assist in weight management?

Resistance training assists in weight management primarily by building muscle, which subsequently increases the metabolic rate. When an individual engages in resistance training, the body experiences micro-tears in muscle fibers. The process of repairing these fibers not only strengthens them but also requires energy, thus burning calories even when at rest. This sustained increase in muscle mass contributes to a higher resting metabolic rate—meaning that the body burns more calories throughout the day, which can aid in weight loss and weight maintenance.

Additionally, increased muscle mass enhances overall body composition, as muscle tissue is denser and more metabolically active than fat tissue. This shift can lead to a more favorable balance between energy intake and expenditure, facilitating better weight management and promoting overall health.

In contrast, the other options suggest either negative outcomes of resistance training or inaccurate associations with weight management, such as muscle loss or promoting fat storage, which wouldn't be aligned with the benefits of resistance training.
