Level I * Upper Body * Hand and Arm Strikes

Hand and Arm Strikes are one of the Level 1 basics of Motion Science and one of the basics of Kenpo Karate. Strikes can be offensive or defensive moves used to hit an opponent's vital and non vital areas.

Following are the basic types of hand and arm strikes studied in Motion Science.

Arm Strikes


Just about every part of the arm, from the hand to the shoulder can be used as a striking weapon. Hand strikes were reviewed in the previous section, so here we’ll focus on the rest of the arm.

Striking Angle and Path or Arc

All strikes and blocks – arm or other – can be traced along the universal pattern. The striking weapon can follow any of the below lines or arcs. Moreover, the pattern itself can be positioned at any angle along any of the three dimension of space. For example, with the pattern facing you along the up-down axis, an upward elbow as in Obscure Wing or a downward elbow as in Crossing Talon can be represented. Lay the universal pattern down (as if on a table), and a forward elbow as in Shielding Hammer and a reverse elbow as in Locked Wing can be represented. (Another example of a forward elbow would be a collapsing elbow sent into an opponent who blocks your straight punch from the outside, but between the elbow and the wrist.) Alternately, the strike can follow one of the circle’s arcs as in the sandwiching elbow in Snapping Twig. Or it can follow an arc with the pattern on a 45% angle across the width and height zones, as in Deflecting Hammer.

Universal Pattern

Similarly, more than one arm strike can be executed simultaneously, following different lines or arcs in the pattern. For example, in Flashing Mace, the initial inward block/extended outward block combination form kissing circles that work together to hyperextend the opponent’s elbow.

Also, note that the body can also move along the universal pattern as the arm moves with it or in a different direction. The second outward block in Short 1 uses reverse torque, with the body and arm moving along circles in opposite directions. As another example, the body can spin but still send the weapon straight, as in the spinning elbow in Captured Leaves.

Striking Surfaces

Just about any surface of the arm can be used as a striking weapon.
