Integrated Grappling Systems
Take Downs to Controlling to Submission Workshop

Conducted by Ron Kosakowski

Sunday December 4th, 2011, 10:30am to 4:30 pm

Lunch break for approximately one hour (it would be best to bring a lunch if you can)  


For those of you who would like to learn powerful take downs into controlling your opponent to possible submissions, this is the workshop for you. This is good for those interested in learning more about a good tactical approach from various grappling styles that are in the IGS style. You will also learn how to be deceptive in your take down entries, maintaining tight position and controlling your opponent on the way to submissions. If you are doing submission wrestling tournaments or MMA fighting, this is a workshop you will not want to miss out on. For self defense purposes, this will help you understand how to defend yourself in a clench that much better.

Great news for Law Enforcement personnel - this Take Down workshop is also very good for any type of law enforcement personnel looking to understand grappling and controlling an opponent by means of any extreme necessary!

IGS is a blend of over 20 years of Brazilian Jiu Jitsu, Sombo, Judo, Shooto, Catch Wrestling, with Dumog, Silat and Kuntao added for more self defense potential in worse case scenario situations. Where one style has an empty space, there is another to fill that void.

Knowledge is power as long as you know where, when and how to pull off that knowledge! Integrated Grappling Systems, aka - IGS developmental skills are very valuable to those looking to have a complete understanding of survival skills for any type of combat situation involved with standing clench to ground work. Male or female; regardless of size or strength, you will not want to miss this opportunity to train in this unique blend of grappling styles from all over the world!

Here is the predetermined schedule for the upcoming workshop:

  • Sunday, January 31st - IGS submission grappling 10:30 am - 4:30 pm 

Certificates of participation will be given out at the end of this workshop. For people looking to go to eventually achieve Instructor Level. Each certificate will be accredited toward hours attending each training workshop. Call Ron Kosakowski if you need more information on long distance student training!
