There is no meat on the boys' chest muscles, and the ribs are obvious. What should I do?

Don't worry, as long as you eat and sleep normally, control several groups of push-ups for 20 minutes every day, and then gradually increase them for several months, which will be effective. I have been working out for more than 3 years. Before 55KG, I was 170cm thin. I did push-ups at home before going to the gym. At that time, it was generally better to chase girls. I practice 1 hour every day for less than three months. The classmates said that it was obviously different from before, and the chest muscles were a little smaller. Haha, I'm glad to hear that. Although the girl still didn't catch up, my confidence greatly increased, and then I went to the gym to exercise. I am very happy. Now 167KG is all muscle. There are 7 or 8 positions in push-ups. Search online. Of course, men should look safe. Wish you success!
