Lately I've been doing serious and heavy dumbell shrugs. Let me tell you something, my traps got noticeably bigger. Just a couple days ago I put on a shirt I haven't worn for about a month, and the length is no longer working for me, it's too short. Tried a few other shirts that I haven't worn and I can no longer wear them. Now I am trying more deadlifts, and hopefully I get better development. I love how traps make you look more powerful, they, quads and triceps have become my target muscles for the next 3 weeks.
