Uses for the Loose Hook: A Loose Hook is a close range punch.  It is best executed inside, when a straight punch lacks effectiveness.    It is effective as follow up in a combination of attacks.  It is generally not a leading attack. The targets for this strike are numerous.  It can be employed to strike the head, ribs or even the groin.

The Mechanics: To practice the punch individually, the target is approached in a stance that is a little more square than usual.  Squaring off enables the use of both hands freely.  Also, with the feet closer together it becomes easier to Bob & Weave, Slip etc.  The body is relaxed to faclitate the whipping motion that will generate the power in this hook.  The rear hand remains near the chin to protect the head, while the lead is held a bit lower, ready to strike.  Initiating the punch, the hips open slightly and turn towards the point of impact.  The lead hand whips outward, thrown by the the momentum of the hips.  The elbow turns upwards, lining up behind the fist.  The arm is raised almost to a 90° angle from the body.  (this angle may vary according to the height of the punch).  The leading foot follows the same direction.  The rear heel is lowered as it turns to open the hips.  Upon impact, the front foot lands with the heel raised.  The rear turns to complete the power line.  This "power line" is crucial in the generation of power.  Using the hips, the the punch follows through the target, ending three to five inches behind it.

Summary: The Loose Hook is an extremely powerful punch when landed correctly.  For many, it proves to be difficult to perfect but it is a weapon that is well worth the time invested.
