Definitely agree with Jackal, I have decent genes when it comes to the trap department and that accounts for a lot of what develops on individuals. I just recently started doing dead's and they are great, I used to only do shrugs and still had nice traps. People may not agree with this but I think behind the neck military press helped my traps also. Everybody is different bro, try different things. You won't know until you try it for yourself. This game is about dedication.
