Resistance training plays a vital role in weight management by increasing muscle mass and boosting metabolism. As muscle tissue is more metabolically active than fat, having increased muscle mass leads to higher energy expenditure, even at rest. This can result in a greater caloric deficit, which is essential for weight loss. Additionally, resistance training can improve body composition and lead to better insulin sensitivity, helping to manage blood sugar levels. Regular resistance workouts can also prevent the loss of lean mass during weight loss, supporting sustained weight management.
