First of all, I think men with broad shoulders feel more secure. With such people, I feel like an innocent girl. Secondly, the older generation thinks that men should be strong, because men are the pillars of the family, and it is not good to be thin and small. Personally, I prefer boys with wide shoulders, thin shoulders and uncomfortable heads. Hehe, I hope my answer is helpful to you. The shoulder is deltoid. The deltoid muscle includes three parts: front, middle and back. When exercising, exercise separately, and don't use too much weight. Primary exercisers should focus on mastering exercise skills and try to use the minimum weight. After two or three months of exercise, you can consider adding weight or using some tips to enhance the exercise effect. When exercising, choose the exercise sequence according to your own situation. It is suggested to exercise the weakest part first, and then exercise the stronger part.
