Including guillotines in your Brazilian Jiu-Jitsu game is beneficial as it offers a powerful and versatile submission option that can be applied from various positions, making it an effective tool for both offense and defense.

Our Amazing Coaching Team

Head Coach, Jiu-Jitsu Black Belt & Kick Boxing Black Belt
Lee Tierney
Ever since I earned my brown belt in Jiu-Jitsu, my journey has been nothing short of transformative. Diving deep into the art, I have devoted myself to mastering the fundamentals, recognizing that a strong foundation is crucial for any advanced technique. My approach on the mats is methodical and deliberate, emphasizing the importance of basic positions, transitions, and submissions. This focus on the basics has not only sharpened my skills but also deepened my understanding of Jiu-Jitsu as a whole. I’ve learned to appreciate the nuances of each movement, understanding how even the slightest adjustments can significantly impact my game. My dedication to the fundamentals has become my greatest strength, allowing me to execute techniques with precision and effectiveness.
One area where my commitment to fundamentals truly shines is in my pressure passing game. Known among my peers for my relentless pressure passing, I’ve honed this skill to become a defining aspect of my style. My approach to passing guards is systematic and heavy, always maintaining control and applying constant pressure. This strategy not only helps me in advancing positions but also wears down my opponents mentally and physically. I’ve become adept at reading their movements and reactions, using this insight to adjust my pressure and angles, making my passes nearly unstoppable. This aspect of my game has not only led to numerous victories in sparring and competitions but has also become a part of my identity as a brown belt in Jiu-Jitsu, showcasing my belief in the power of fundamentals and the effectiveness of a well-executed pressure game.

Guillotine & Defensive Game Specialist, Brown Belt
Keelan Rodriguez
As a brown belt in Jiu-Jitsu, my journey has been characterized by a deep dive into the art of defense and a specialization in guillotine chokes. This phase of my training has been about understanding the essence of ‘less is more.’ I’ve refined my ability to maintain composure under pressure, focusing on defensive strategies that not only protect me from submissions but also create opportunities for counters. My game is about patience and precision, waiting for the right moment to exploit an opponent’s overextension or mistake. This defensive mindset has not only enhanced my resilience on the mats but also taught me the importance of strategic thinking in Jiu-Jitsu. It’s a chess game, and each move I make is calculated to ensure maximum efficiency with minimum risk.
My reputation as a guillotine specialist has become a cornerstone of my style as a purple belt. The guillotine choke, for me, is not just a submission but an art form. I have dedicated countless hours to perfecting the nuances of this technique, from various grips and setups to understanding the subtle body mechanics involved. This specialization has made my opponents wary and cautious, as they know a single lapse in their guard could lead to a swift and decisive end. My ability to seamlessly transition from a defensive posture to locking in a guillotine has become a feared and respected aspect of my skill set. This dual focus on airtight defense and mastery of the guillotine choke has not only set me apart in competitions but also shaped my identity in the world of Jiu-Jitsu, representing a blend of patience, precision, and the sudden, explosive execution of a well-honed technique.
