There is nothing quite like a guy with large traps. Somehow they make him look huge all over. Huge traps can be achieved by doing heavy deadlifts on a regular basis.
Deadlifts are an amazing exercise. There is no other exercise that makes me feel as strong as deadlifts do. There is something about picking up an extremely heavy object off the floor that makes me feel like a beast. At the same time, I have seen how doing heavy deadlifts has transformed areas of my body.
When I deadlift at least 2 times a week my traps grow like weeds. That makes me look bigger than I am. I notice that I get comments from others about my size when I am deadlifting regularly. This one exercise changes my physique more than any other.
If you want to build huge traps start out slow. Check your ego at the door. Take the time to learn proper form. Slowly increase the weight as you master the proper form. Before long you will be lifting very heavy weights. I can now move well over 400 lbs with ease but it wasn't always that way. The wait will be well worth it. Your traps will begin to grow and grow.
If you are not already deadlifting regularly get going on it. It improves every part of your body.
