Arms trapped - visual swing fault

A very common "visual" swing fault is the arms being stuck to the body or pinned to the torso and not properly releasing into impact. This video explores the cause of the issue on a biomechanics or sequence/coordination level and how to approach resolving the swing fault.

The swing fault is almost always mis-diagnosed as the body moving too fast for the arms as a result the remedy revolves around the body - hips/torso being too fast and the arms being too slow. 

In fact the issue is almost always the arms being too fast or too quick to accelerate.  The arms initiate the downswing rather than the lower body and disrupt the kinetic link sequence.  The torso then accelerates late in the swing, out of sequence, giving the appearance of the arms being trapped behind the body.
