Hey guys i can do OACs starting from just above dead hang but can't even move at all starting from dead hang. I heard that you need to retract your scapula in order to start the initial pull and bend your arms. Is this correct? I was thinking of doing max holds with a retracted scapula from just above dead hang and then slow negativing into dead hang keeping the scaps retracted. Also just retracting the scapula in a dead hang and holding in order to gain the strength in it. Is this an effective way to get a dead hang OAC/OAP? And most importantly, should the scapula be retracted to start the pull - so should i mainly focus on retracting hard to start it?
