  For those of you who are curious about learning Kuntao, as it is taught by Ron Kosakowski, here is your chance to see something very unique.

At this workshop, you will learn some typical defenses and hand movements monitoring the opponents hands. This will show you how to be there before your opponent is when confronted with or without a weapon. You are going to learn the step by step progression it takes to gain the reflexes to pull off what you learn here at this workshop. There are many steps to bring you to the point of random play. You will then learn the vicious counters to your opponents attacks found in this style of Kuntao.  

Size and strength does not matter once you master this style. There are some very violent fighting methods when really needed most within this style. This workshop will change your views on all ranges of confrontation for the objective of self-preservation. Kuntao is a blade oriented martial art style. Hence the reason this angulated fighting methodology you will learn at this workshop is so effective. Only weapon based systems have the attribute of deception and good evasive footwork as part of the system built in already. 

This is a good seminar to attend to gain a good foundation for the 3 day Kuntao camp July 25th, 26th, and 27th
