HADI is spot injecting (once again) !!
Every single one of them do it. Yes I know you know it and this is just a jab at Hadi (I think?)

I've said the delts are one third oil (and scar tissue) on every pro, and even if it's a slight exaggeration it's not by much. If you don't use oil in your rear delts fan think you are neglecting training your rear delts. You need that rear delt shelf you can see even from the front

Nasser said it, everyone uses it except himself, he was a man of truth.
