Have you ever heard of a motor engram? Motor engrams are your ticket to the awesome movement speed you've always wanted. Notice I said, "movement speed," not "speed." As I said in The Book of Speed for Martial Artists: "There is much more to speed than just moving fast." But, moving fast is vitally important to effective speed and it's what everyone wants.
Most martial artists believe that movement speed is only earned through reps and sweat. For the most part, that's true. But, if you really want to get the job done, you need a few more ingredients. Science can give us the recipe for making those reps, and that sweat, much more effective.
Science tells us that all movement is based on reflexes. When you were born, reflexes were all you had. That's why someone had to stick your pacifier in your mouth for you. Learning to pop it into your mouth yourself required your brain to learn how to organize and utilize those reflexes. In fact, all complex movement is the result of our thinking brains learning to organize and control reflexes. The result is a bunch of memories in your head that tell your body how to move.
