No matter how detailed it is, you can't grasp it. In addition, it is recommended to do push-ups. Don't let the child do push-ups again, it will aggravate his hunchback. Your child's problems must be solved by a professional coach, at least explain the principle to you. Do you remember the muscles I mentioned: your child's pectoralis major, pectoralis minor, subscapular muscle, deltoid toe, latissimus dorsi and teres major are all tense and need some relaxation and massage. In addition, we should strengthen the training of core muscles such as rhomboid, infraspinatus, teres minor, posterior deltoid, erector spinae and transverse abdominis. In addition, your child should still have a leading position, so it is necessary to strengthen the training of deep neck muscles. When you meet the coach, let him talk about the principle of this bad posture, where to relax and where to strengthen. If he can answer well, then. Don't worry. Give him the baby. If not, don't waste time with him. I hope your child will stand up to a man's chest as soon as possible.
