First you must develop strength, by repetition of straight lines. As you develope your abilities to control your (body’s) maximum range of movement, power is being built. Power is the effect of strength controlled through range of movement. When you posses powerful movement from each corner-range, speed will be accurate. Speed is the coalescing of strength and power. Strength is the tool for reaching the ‘end’, through the path of least resistance. Power is the tool to push back at obstructions before you reach this end. Speed is achieved when nothing stands in your way. Swing the long spear and understand both the strength and power it takes to move swiftly and accurately. ~Dan
