I've been doing scapular push-ups, dumbbell raises, dumbbell rows (and db rear delt rows), as well as various resistance band exercises and stretches.
I was just wondering if throwing in a few shrugs after doing my shoulder presses would be counterproductive. Should i be doing lots of scapular depression training to compensate? I'm not even entirely sure what scapular depression entails. Do pull-ups count?
Have you been following the NNM program to the letter and for how long.
It would probably be better to start a new thread, detailing how long you've been training, what your programs have been like past and present.
Then we can see how much pushing versus pulling you've been doing and how you've come to the conclusion you have winged scapula. Also, what stretching you have been doing. The wrong stretches could be counter productive.
Scapular depression happens when you pull your shoulders back and down, think of putting your scaps in your back pockets. Do this a few times without any weights, while you sit watching TV for example and you'll get a feeling for it. This is the feeling you need to replicate when doing weighted movements. The temptation is to use way too much weight though and you'll notice that its much harder to achieve this. So start REALLY light and only add enough weight that allows you to maintain correct form. This is important. You can go heavy when you have corrected your issues an a few months.
By the way, pull-ups can never hurt in my opinion, they should be a staple in all programs.
