Scapular Retraction and Depression

Getting on dip bars and doing a reverse shrug be scapular retraction and depression? or only one of them?
Would doing this be an effective way to train the movement?

is this a trick question because it has that feel to it…

um…

a shrug involves scapular elevation. so a reverse shrug would involve scapular depression.

retraction is squeezing your shoulder blades back together. like a face pull.

if you want a combo depression/retraction…

how about depressing them then doing a facepull.

i think that would be easier than retracting them before doing an anti-shrug. but maybe not.

why you wanna do this for dare i ask?
