Hello, this friend is coming down. Let me answer your question. Judging from the photos you sent, this lady, your mother, is still very thin. Good guess, the body proportion is relatively coordinated. I think he should keep good living habits. Habits are also healthy. Only long-term persistence can keep such a good figure. His figure is worth learning from each of us. The direction of efforts. I am fat, and I envy such a thin person at all. I look good in clothes, too. I envy you.
