about super sweet science boxing
Whether you’re a beginner looking to learn the fundamentals, an athlete training for competition, or someone who wants to unlock their inner fighter, Super Sweet Science Boxing is the place where your journey begins.
Boxing Isn’t Just a Sport — It’s a Science
At Super Sweet Science Boxing, we believe boxing is more than throwing punches — it’s about discipline, intelligence, and transformation. Our philosophy is rooted in the art and science of boxing — teaching fighters how to think, move, and adapt like true students of the game.
Founded and led by Coach Jason “The Boxing Nerd”, Super Sweet Science Boxing combines decades of boxing experience, evidence-based training, and personalized mentorship to help each student reach their highest potential — whether that’s stepping into the ring or simply becoming stronger and more confident in everyday life.
Our Mission
To help people build confidence, discipline, and strength through the science of boxing — one student, one session, one victory at a time.
We believe boxing has the power to transform lives. Every jab, every round, and every lesson is a step toward mastering not only the sport — but yourself.
Unlike typical boxing gyms, we specialize in one-on-one private coaching — giving you undivided attention, detailed feedback, and customized progress tracking. Every punch, movement, and reaction is refined until it becomes second nature.
Our Boxing Coaches
Jason Hartstein
Head Boxing Coach & Co-Founder
Since 2017, Jason has been obsessed with the Sweet Science of boxing—training alongside high-level amateurs and professional fighters, and developing a reputation for seeing what most people miss.
That eye for detail naturally pulled him into coaching, where he’s helped shape everyone from total beginners to serious competitors, including multiple provincial gold medalists, and top national athletes.
Jason is known for deep, expansive, technical, intentional padwork and a teaching style that turns complex boxing concepts into clear, repeatable systems.
He studied elite coaches from around the world and distilled those lessons into practical methods fighters can actually apply—under pressure, in sparring, and in competition.
An NCCP-recognized boxing coach and the Head Boxing Instructor leading the SSS Boxing Program at Modern Warrior, Jason is building a handpicked team of SSS-accredited coaches who share one mission: raise the standard of boxing coaching and help athletes reach the highest levels through the Super Sweet Science Boxing System.
Keith Liu

Keith is a true student of boxing—disciplined, analytical, and relentlessly committed to getting better.

Alongside Coach Jason, Keith has been an instrumental piece in bringing success to the competitive team, prepping them for their successes in the recent provincial-level tournaments.
Keith has a rare mix: a sharp technical eye and the patience to teach.
He breaks down mechanics with clarity, spots the small details that make the big differences, and helps students build real skill—not just get a sweaty workout.
Whether you’re learning fundamentals or sharpening your game, Keith coaches with precision, structure, and genuine care for your progress.
Coach Jason on Keith:
