I just can 't make my shoulders to grow as fast as the rest of my muscles. They are really my weak spot I have tried for a long time but I see no results. I lift more than almost everyone in the gym but they just wont seem to grow. I have tryed 6 reps and 8 reps and now i am going for 12. Should i try more reps with less weight on?I am really desperate because I look really big and it is noticable that it is my weak part
