Resistance training positively affects body composition by increasing lean muscle mass and reducing body fat. This type of exercise stimulates muscle hypertrophy and can elevate metabolic rate, leading to greater calorie expenditure even at rest. Enhanced muscle mass contributes to a more toned appearance and improved overall strength. Additionally, resistance training can help regulate body composition by improving the body’s insulin sensitivity and hormonal balance. As a result, consistent engagement in resistance training often leads to a healthier body composition and improved physical capabilities.
