For men around the age of 40, the body shape will change more or less, and the fat in the waist and abdomen will begin to accumulate. Men in this age group also have strong athletic ability, and they can lose weight by doing some aerobic exercise. For example, jogging, cycling and swimming, aerobic exercise can not only lose weight, but also exercise people's cardiopulmonary function, making middle-aged people's hearts younger and healthier.

2. Living habits

Many middle-aged men have the habit of drinking, but they don't know that drinking can lose weight. Alcohol can make the cholesterol level in the human body rise sharply, thus making men obese, so if you want to lose weight, you must first give up drinking. On the other hand, the usual diet should not be too greasy, otherwise it will lead to the accumulation of oil in the stomach and make the body out of shape. Try not to stay up late at ordinary times, and it is best to fall asleep before eleven o'clock, which can better restore the vitality of cells.

3. Aerobic fat reduction.

Men lose weight by actively using oxygen to reduce fat. Since there is fat in the chest, practice chest exercises such as arm flexion and extension, downward oblique bench press and so on. These actions can improve the shape of the lower chest and make the chest developed. However, the fat content has not decreased, and there will still be ugly "fat" on both sides of the lower chest.

Reducing fat requires aerobic exercise, and simple instrument training is anaerobic and cannot effectively reduce fat. If we can reduce subcutaneous fat, we can gradually eliminate excess fat in the chest. Therefore, certain aerobic exercise can reduce fat, and the "fat" in the chest can disappear. Aerobic exercise includes running, swimming and spinning.
