Don't do push-ups Your pectoralis major is overdeveloped locally, and other parts can't keep up. Just doing push-ups will lead to overdeveloped toe beam of deltoid muscle, which is very uncoordinated. It is recommended that you practice the inclined plate bench press (leaning upward). You can tilt the bird with dumbbells without barbells. If possible, you can cooperate with the stretcher to clamp your brother (develop the inner edge of pectoralis major). Pay attention to the heavy weight and low frequency of each group, and each group will be exhausted, at least. Don't leave too long between groups. You should be able to balance your chest muscles in three or four months. I am also a fitness enthusiast, and I hope I can help you.
