How does resistance training affect body composition?

Resistance training significantly influences body composition by increasing lean muscle mass and reducing body fat. This form of training stimulates muscle hypertrophy, which is the enlargement of muscle fibers, thereby enhancing overall muscle mass. Increased muscle mass contributes to a higher resting metabolic rate, meaning that the body burns more calories at rest.

Furthermore, as resistance training is performed regularly, it also encourages fat loss through a combination of metabolic adaptations and improved insulin sensitivity. The energy expenditure during and after resistance training, often referred to as excess post-exercise oxygen consumption (EPOC), can contribute to further fat reduction.

In essence, combining resistance training with proper nutrition can lead to a more favorable body composition, characterized by increased muscle and decreased fat, ultimately promoting overall health and fitness.
