Strength training improves metabolism by increasing lean muscle mass, which is more metabolically active than fat tissue. This means that, at rest, individuals with greater muscle mass tend to burn more calories. Regular strength training can enhance the body’s ability to oxidize fat by improving overall body composition. It also contributes to the elevation of the resting metabolic rate, allowing for greater energy expenditure even when not exercising. This cumulative effect can support weight management and fat loss goals.
