Isn't it cool how getting the form of the technique correct makes the power of that technique increase. I constantly find that by focusing on certain techniques I can cut out the extra slop in the movement and increase power. An example of this was the simple chudan-tsuke. I dont know how I got off track in my punching, but I did. My elbow was flying out every once in awhile. Once corrected I saw huge gains in speed and power.
It just goes to show you that less is better. Simplify and things work out.

keep training, Mark
