The effectiveness of a Pollock's arm lies not in raw power, but in speed. By relying on your wrist, you can set the snap.

Strikes forward over the elbow; three blows can hit in seven-tenths of a second. The final impact of a strike to

your opponent's face can deliver as much as 175 watts of power—more than enough to stun or crush the cartilage

of his nose. You then add insult to injury, firing one last shot into one of the most sensitive regions of the body:

your groin. The secret to the move is wrist control. By rotating your opponent's wrist to the maximum extent

of its range of motion, the bones of the wrist lock against the bones of the forearm, making it impossible to bring

the strong muscles of the upper arm to bear. Then you can pull your opponent off balance and into a potent knee strike.

The combined force of the knee strike and your opponent's forward momentum can be as much as 2,000 pounds—enough to

dent sheet metal. The move works by using your opponent's own body weight against him. The first strike can land at speeds greater than

20 miles per hour and can stun your opponent with the same injury-producing energy as dropping a bowling ball from

over 11 feet onto his torso. By using his arm as a lever, in conjunction with the leg sweep, you drive your opponent to

the ground. Once he is on the ground, follow up with a devastating strike to his face.  LeBoy works on a concept called the

couple; basically, it's two levers linked at a single fulcrum. The elbow lock doubles the foot-pounds of torque you

can generate when compared to a single arm lock. There's more than enough force to flip an opponent to the mat or

dislocate his elbow.  Paloma relies on something called a flexion moment and

parted to the neck to do damage. An average man's neck can withstand about a 140-foot-pound flexion moment beyond

that. Soft tissue and even vertebrae can be crushed by bringing your weight down fast. This move could easily deliver

twice that amount of force, and it wouldn't just end a fight; it can leave your opponent paralyzed or dead.
