ABOUT

The more one studies Ueshiro Shorin-Ryu Karate, the more one appreciates its natural efficacy. Its underlying principles exploit both the physical laws of nature and the body’s inherent strengths and weaknesses to maximize the potential to defend and counterattack. Master Ueshiro exemplified these principles in every aspect of his training. Some key principles are:

General:
· Shorin-Ryu is a natural style with little wasted motion, no exaggerated breathing; and there is no technique, if done properly, that poses risk of self-injury
· Techniques are direct and linear (“hard style”)
· Relax and breathe (shoulders down). The body is erect and relaxed until kime.  (Except the hands whose fingers are always together, the feet which grip the deck, and the eyes which “are alert, opened wide then narrowed by drawing up the lower lids creating a spirited glare.”–from Building Warrior Spirit, page 18.)
· Primary targets are on the midline of the opponent
· Aim for a small, specific target when striking
· The striking surface is aimed at the target throughout the technique
· The smaller the striking surface, the greater the force per square inch into the opponent’s body (e.g., ice pick vs. snowshoe)
· All force should be directed through the target and/or down into the foundation
· Techniques accelerate through the target
· Adding acceleration to a technique multiplies force
· Adding mass to a technique multiplies force
· Adding gravity’s kinetic energy to a technique adds both acceleration and mass
· Train the body to be ambidextrous 
· Both sides of the body are applied to every technique  
· Be aware of your entire 360° perimeter 

Lower body:
· Techniques start from a solid foundation, feet directly beneath the body, feet gripping the deck 
· Step immediately, turning your feet into their final position right away 
· The lower body initiates the force (through hip movement) for each technique
Move forward, take over the opponent’s space with your hara
· When moving between low techniques, stay low. 
· When changing height, the rule of thumb is: when going from low to high, stay low until the stepping foot is in place; and when going from high to low, get low right away
· Kicks accelerate by snapping back
 
Center:
· Every technique uses hip movement (rising hip: both quadriceps; dropping hip: gravity; and rotating hip: rear quadriceps, obliques, then gluteals)
· Most force in each technique is generated by hip movement –get your obi to swing
· The upper body and lower body move independently, even in opposite directions simultaneously when desired
·  The back remains straight throughout each technique
 
Upper body:
· The  hand coming back into the pocket generates as much force as the hand going  out
· Elbow  travel: chamber the elbow closest to midline, then accelerate it laterally  from there (outward and/or forward); plus up or down, if  appropriate
· Forearm rotation: arm  techniques use torque of the forearm (rotational energy) to accelerate  through the point of contact; by starting their rotation just prior to, and  then continuing rotation through, contact
· The force of an arm  technique is the body’s mass as applied by the speed of 1) hip movement, 2)  elbow travel, and 3) forearm rotation

​

As with any list of principles, there are exceptions. However, if you are watching your video of Neko-ashi-dachi Chudan soto-shuto-uke as viewed from the side and you thrust your hip backward during the technique, that rearward-moving hip violates the principle that all force should be directed through the target and/or down into the foundation. Likewise, if you are in front of someone doing Shizentai-dachi Chudan soto-uke and the elbow remains still –acting as a stationary pivot point while the forearm hinges to the side –that violates the principle that the elbow must travel (in this case outward) in arm techniques. (And because his elbow does not travel in this example, the overall body mass applied to the technique –other than that of the forearm itself –is zero.)

Therefore, incorporate the physical principles of Ueshiro Shorin-Ryu Karate to dramatically increase the force in your karate techniques. Such knowledge, which has been passed down through generations of masters to Ansei Ueshiro and on to us, is a true treasure and must be preserved accordingly.

However, as Hanshi Scaglione always reminds us, this is achieved only through hard work and constant practice. Which is true of every art. Because, when you think you have attained some skill, your training will always expose how much you still have yet to do.
