Resistance training plays a significant role in weight management by increasing muscle mass, which in turn boosts the body’s basal metabolic rate (BMR). Higher muscle mass leads to greater calorie expenditure, even at rest. Additionally, resistance training improves insulin sensitivity and helps regulate blood sugar levels. It can also aid in reducing body fat while preserving lean muscle, creating a more favorable body composition. Combining resistance training with aerobic exercises and a healthy diet enhances overall effectiveness in maintaining a healthy weight and preventing weight-related issues.
