Sebastian Brosche, founder of Yoga for BJJ, has stirred up controversy with his stance on who should be teaching beginner Brazilian Jiu-Jitsu classes—and it’s not black belts.
“I believe the best Jiu-Jitsu teacher for beginners is blue belts,” says Brosche in appearance on Grappler’s perspective podcast. “If you take a blue belt that is good at teaching, they’re going to teach a much better beginner’s class than a black belt.”
The Logic Behind Brosche’s Argument
Brosche’s reasoning comes down to relatability and perspective. While black belts have years of experience, they often suffer from “expert bias”—where their deep understanding of the art makes it difficult to empathize with beginners who struggle with basic concepts. Blue belts, on the other hand, have just recently navigated the early struggles of Jiu-Jitsu themselves and can more effectively relate to new students.
“The blue belt just went through the journey, they have all the relatable stories still fresh in their mind, and they’re really motivated to help because they’re still excited about Jiu-Jitsu,” Brosche explains.
According to him, beginner classes shouldn’t emphasize technical terms like “closed guard” or focus on complex concepts. Instead, they should prioritize fundamental movements, self-confidence, and comfort on the mats. In this context, blue and purple belts may be better suited to introducing newcomers to the sport than seasoned black belts who might overwhelm them with technical details too early in their journey.
Brosche claims that this approach has been successful, pointing to a purple belt who implemented his teaching framework and achieved 100% retention of new students—an impressive feat in a sport known for high dropout rates among white belts.
The Controversial 14-Day Teaching Course
However, Brosche’s stance on beginner instruction hasn’t been met without resistance—especially given that he is selling a 14-day online course designed to certify individuals to teach Jiu-Jitsu, even if they are not black belts. The course, marketed through TeachGrappling.com, claims to provide the necessary teaching skills in just 10 hours of content.
“No other instructor will be as prepared as you. This is the way for a purple belt to compete with black belts for a job as a head instructor.”
For some, this is a step toward standardizing beginner instruction in Jiu-Jitsu. For others, it reeks of commercialized shortcuts reminiscent of “McDojo” belt mills. Online discussions have ranged from skepticism to outright satire, with critics likening the program to fast-tracked certifications seen in other martial arts franchises.
The Bigger Debate on Instructor Legitimacy
The issue isn’t just about Brosche’s course but taps into a larger debate about legitimacy in martial arts instruction. While it’s not uncommon for blue belts to assist in teaching in areas with limited access to black belts, the idea that a two-week online course could create competent instructors raises concerns about the dilution of quality instruction in Jiu-Jitsu.
Some supporters argue that the program doesn’t claim to turn someone into a high-level practitioner overnight but merely provides a structured way to approach teaching. If framed as a supplementary tool rather than a substitute for hands-on experience, it could have value. However, given the martial arts community’s long-standing skepticism toward commercialized certifications, it’s unlikely this debate will settle anytime soon.
With Brosche actively promoting his teaching philosophy through both his course and his upcoming training camp, it remains to be seen whether his approach gains traction or continues to be a point of contention within the grappling world.
