Any information on dip shrug / serratus shrug?

[opitica]

I've seen forum posts and mens fitness magazines that talk about the dip shrug (shrugging shoulders on dip bar with locked arms) to target the serratus anterior but I can't find any authoritative information on the movement. Does anyone have a reputable source in what muscles the movement uses besides the serratus anterior?

@opitica:

Shrugging the shoulders is an example of elevation. The traps are the dominant muscles in any movement where the shoulder girdle is raised.

Doing shrugs in the push up position (also called push ups +) will more directly work the serratus.

Stu makes a good point - doing shrugs on a parallel bar doesn't put the serratus muscle in a strong position to do work.

If you look at the serratus exercises listed on this site, the common element is moving the shoulders forward (albeit on an upward incline), not directly upward. And overhead presses work the serratus, as well.

The biggest problem with the serratus is that you have to be pretty lean for them to be impressive looking
