Resistance training influences weight loss by building lean muscle mass, which increases resting metabolic rate. More muscle burns more calories, even at rest, contributing to overall fat loss. Regular strength training, combined with a balanced diet, leads to better composition changes, helping individuals achieve their weight loss goals more effectively. Additionally, resistance training can enhance strength, boost metabolism, and improve body function. It also promotes healthy hormonal responses, aiding in weight loss efforts. Thus, it's a vital component of a comprehensive fitness program.
