Arm around in lying

You never know, in life, when you're going to be stuck up against a wall and need to reach into your back pocket. If this function concerns you, this is the lesson for you. On the other hand, you may have more generalized interests, like ungluing your shoulder blades, freeing your neck, or undoing patterns of holding in the abdomen that limit everything else you do. This lesson can help you with those things too.
