Resistance training significantly reduces body fat percentage and increases fat-free mass in middle-aged, android-obese men, whereas aerobic training does not significantly alter body composition.

If you are overweight with abdominal fat, incorporate resistance training 3 times a week. Focus on major muscle groups with moderate weights. This approach can significantly reduce your body fat percentage and increase lean muscle mass, even without changing your diet.
