You asked for a division with heel hooks, and we heard you.

Proving Grounds is now featuring an Elite No-gi Division using the Global Submission Grappling Rule Set.

Everyone signed up in intermediate and advanced No-Gi divisions can join the Elite Division at no extra cost.

Wondering who the best of the best is, then enter the single-elimination bracket style tournament talking place in addition to your other divisions.

So if your about that life, Prove it! in our Elite No-Gi Division at Proving Grounds.

Fact:

In terms of the number of matches a competitor gets to take advantage, a (4) person Round Robin is equal to or better (depending on the day you’re having) than an (8) person single elimination tournament. more matches, more learning. (round robin all-day)

In an effort to stay true to our mission of offering the best possible tournament format, we will be making a few significant changes for future events. The following changes should make for a more exciting, competitive, and inclusive event.

1. Most “Dominate Academy” award. This title will be given to the academy (defined by a single address/location. Not to be mistaken with affiliation/multi locations) with the greatest number of submission finishes.

2. Due to many requests, we are now adding a “Master 4” division for competitors 50+ years of age. It is our hopes that this will bring many more of our “not as young as we used to be” competitors out for a day of fun on the mats.
