I have read the posts about body mechanics to develop speed. Correct hand speed can only be dictated by the lower body. Proper position of the legs/hips to bring power and speed. I will use 5 swords as an example. Everyone here should know this technique. When stepping forward you are to be in a right neutral bow. From this position you rotate into a forward bow with two strikes on the same rotation. While rotating in a forward bow you strike with the front hand then rear hand. The rear hand can only travel with the rotation of the hips. No rotation no power or speed. (this could be a reason why people think kenpoist have a lot of hand speed) Now to move into the uppercut you must shift back to the neutral bow gaining power with the strike. Sure you could uppercut from the forward bow but there won't be all of the torque or body fusion with the strike. Only striking with the arm. I suppose the next move depends on your lineage/instructor or so forth. The left hand strikes the side of the neck to pull the attacker down. Once again for the fifth strike uses marriage of gravity while turning the hips into a right wide kneel. (I personally use the wide kneel because of being smaller I find it more effective "personally") Now if you want to take it a step further. As the right hand slices through the neck the left palm heel comes up to strike the chin both slicing through their respected targets. Shift your hips into a right reverse wide kneel when slicing the two strikes. This opens the throat for the seventh handsword to the throat. Pick your available target for the back kick and leave the scene. My point on this is sure everyone can do all 7 strikes standing still or slightly moving but if the lower body is working together with the upper the hands will becomes less powerful & your speed will diminish greatly. In this technique we learn 2 strikes on one rotation. Five swords is just a great technique that each hand/arm can pick up the next punching hand if thrown in succession. I really believe that this is one of the tech. that everyone thinks kenpoist hands are extremely fast that's why I used this for an example. Thanks for reading all of the way through and hopefully you aren't rolling your eyes at me.
