Your first question: the upper circumference has not changed. A: Although aerobic exercise is the best way to lose weight, it is mainly a systemic weight loss, and it is difficult to specify a certain area to lose weight first. This means that it is difficult for athletes to know where the fat will be consumed at this moment or the next.

Your second question: Why does aerobic exercise make your chest smaller? A: What you lose at this time is mainly the subcutaneous fat in your chest. Strictly speaking, this is not the part of the breast. Of course, if aerobic exercise lasts for too long (moderate intensity, more than 1.5 hours per day), it will indeed reduce some adipose tissue in the breast in addition to reducing subcutaneous fat in the chest.

Your question 3: Do you need to do push-ups? A: After all, doing push-ups is anaerobic exercise, which does not help to lose weight. However, proper push-ups will increase the pectoralis major muscle, not only increase the size of the chest circumference, but also make the breast shape better and less prone to sagging.

Your question 4: How to do push-ups? A: Is there anything special about women doing push-ups? I don't know. I guess it's similar to men. At least you can refer to it: generally, three or four groups a day are appropriate; Every time you do it, slow down; Rest for 30-60 seconds between each group; The number of each group until you can't do it yourself (6- 12 is better); If you can do a lot, you need to do it with a heavy load or at a slow speed. It is best to exercise your chest muscles every other day. In addition, there are many ways to do push-ups: 1, arm width, pectoralis major, pectoralis major side; 2 narrow arms (tired), mainly long pectoralis major and the inside of pectoralis major (easy to form cleavage); 3 hands are low and feet are high, mainly in pectoralis major and upper part of pectoralis major;

Another thing to note is that there are certain conditions for using aerobic exercise to lose weight. 1 Be sure to stick to it, it is useless to fish for three days and dry the net for two days; 2 Exercise time must be appropriate, neither too long nor too short, preferably 40-55 minutes; 3 Exercise intensity should not be too large or too small. The intensity is too great, and the time for persistence is not enough; The intensity is too small and the consumption is too small. The intensity of exercise can be simply measured by the heart rate at that time, and the peak heart rate under 30 years old can be 130 beats/minute; The peak heart rate over 30 years old is 120 beats/min.
