Whats the proper way to do shrugs. Do you roll the shoulders at the top or simply go up and down?
i dont feel that there is a need to roll them even if you only do front or back. the trapezius muscle is an elevator of the shoulders. so by shrugging, youre elevating the shoulder. problem solved. hold for a one sec contration and top. and try to stand upright with shoulders back when you do them. basically do the lift with your delts/traps in the position they are when you are relaxed. this way they will stand more when youre walking around buldging through your shirt
if feel that deadlifts are probably the best trap killer tho
