Important update: After consulting with several coaches and our referees, we have decided to move all of the children’s divisions to the submission only format. Between the high level of instruction on your part and our referees attention to details and regards for safety, I believe the children will be safe with the submission only format. I look forward to seeing you at the next Proving Grounds.

I hope you have all seen the post about Defense Soap coming on board as a Proving Grounds Submission Only Tournament sponsor. It would be very helpful if we could support those that support us. Please go thru the link on the KYS Promotions facebook page or the one below so they can see our support. Also, tell your friends. This is great for Brazilian Jiu Jitsu players, Wrestlers, Catch wrestlers, Judokas, and Boxers as well.
