In general, we are required to move our bodies and limbs to perform various techniques. Moving or twisting our bodies will mainly enhance power, whereas moving our limbs will mainly increase speed. Therefore when we are performing a technique, we have to synchronize the movements of different body parts in accordance with an appropriate sequence and timing, so that we are able to perform the technique effectively with the greatest speed and power. For example, when we are doing “Chudan Tsuki”, we will first move our stance, and then twist our hip and bring our shoulder forward, following the motion, we will push and pull our both arms simultaneously, and finally twist our wrists to do the punching. This is the synchronization of our body motions.
