bigdho pretty much hit it all..good stuff bro..i would add 2 things..first with side laterals make sure you are lifting from the elbow and imagine you are pouring water from 2 jugs i.e ur pinky should be higher than ur thumb at the top..most people use all traps with this b/c they are using to heavy a weight and never target that side head..start light 10 lbs get the right feel...second 1 arm cable side laterals are excellent for width and making your delts look like melons..i saw this in cutler's video where he pulls from behind his body rather in front..i jsut started doing these 2 weeks ago and i love em..
