Your athletic success, engineered.

Systematic Jiu Jitsu and athletic development from a competition black belt. Technique, strategy, body and mind, built into one plan. Lessons from 20 years of training and competing, so you can get there faster.

This is me in Rio de Janeiro, Brazil, after placing 3rd at the Brazilian No-Gi Nationals in 2025.

Hi, I’m Serge Severenchuk. I’m a Brazilian Jiu Jitsu black belt training out of New York City’s Marcelo Garcia Jiu Jitsu Academy. I’m an active competitor in the Adult and Masters 1 black belt divisions.

Jiu Jitsu is my life’s passion, so I want to share what I have learned from 20 years of the Jiu Jitsu grind. Lessons about technique, strategy, optimization, nutrition, athleticism, recovery, psychology, and life. Lessons on the science of performance and the art of fulfillment.

Major competition accomplishments:

  • 3rd place, IBJJF Brazilian Nationals No-Gi (Brasileiro), 2025 (Masters 1, black belt, middleweight division). Brasileiro is one of the four IBJJF Grand Slam events, along with the World, European and Pan American Championships.

  • 2nd place, IBJJF Fort Lauderdale International Open, 2026 (Adult, black belt, middleweight division)

  • 2nd place, IBJJF Virginia International Open, 2025 (Masters 1, black belt, middleweight division)

  • 2nd place, IBJJF New Jersey Spring International Open, 2025 (Masters 1, black belt, middleweight division)

  • 2nd place, IBJJF New York Summer International Open, 2024 (Masters 1, black belt, middleweight division)

What makes my approach unique? I bring PhD rigor to studying Jiu Jitsu. I apply an academic, highly analytical framework to identifying and making improvements. But data and rationality are not enough. To tap into your full potential, you have to go beyond rationality. I also believe that exercising intentional presence, being fully in the moment, allows a practitioner to progress multiple times faster and find true fulfillment in the journey.

I believe in a holistic approach. Jiu Jitsu shouldn’t be just about technique and strategy. It can and should be about developing the whole person. That means health, athleticism, strength and endurance, movement and mobility, nutrition, sleep and recovery, longevity, mental resilience, awareness, and the ability to visualize, believe and think positively. These make a big difference in reaching your goals in Jiu Jitsu. Even more importantly, they make a huge difference in the rest of your life and in realizing your full potential.
