Proving Ground MMA/Vargas Jiu Jitsu

“Coach Ruben has been running his gym for over a decade. His dedication and commitment to the community is unmatched. High level coaching, top quality training, and a family friendly atmosphere make this gym one of the premier schools in the west valley.”

“Got my son has been here for almost 4 years and my husband and i have been doing it for 2 years. The coaches here are all amazing, environment is family oriented, everyone who shows up is super friendly too. I would highly recommend Proving Ground to anyone who is looking into something new!”

“Ruben and his excellent team of coaches have been invaluable in teaching me the skills needed to find humility, respect and confidence in areas I previously struggled. If you want to see these qualities manifested, simply meet his children who are there all the time - they are more respectful, polite and well-spoken than most of the adults that I meet in life. Truly a testament to his character. Great gym. Great people. 10/10”
