Hanging can be divided into:

1. Passive Hanging - relaxed, deactivated, targets more of the passive structural integrity components than the more 'muscular heavy' hangs. It is where more often than not we will start with a beginner. (certain issues with shoulder health and integrity might require we start with active hangs for example)

2. Active Hanging - selective activation of the pattern, engaging musculature and minimizing the demands on passive structural integrity while maximizing the active-component demand and adaptation. Active hangs are a type of strength work. More specifically - Straight Arm Scapular Strength.

CHALLENGE: Hang every time you are in the gym for 5 to 7 min on a bar 

It doesn't have to be unbroken! Start off with 20s on / 10s off or any variation you can do without feeling a shooting pain in your shoulders. Focus on accumulating time not on hanging as long as possible.
