For many amateur athletes, Brazilian Jiu-Jitsu (BJJ) is a hobby, but for decorated black belt and world champion Jazmin Hamuy, it is a life-defining pursuit rooted in grit, mental fortitude, and a relentless commitment to growth.
Hamuy’s path into the sport was not linear. Originally a kickboxer aiming to enter the world of mixed martial arts (MMA), she decided to add BJJ to her training regimen as a secondary skill. However, the complexity of the grappling art quickly captured her focus. “I ended up falling in love with jiu-jitsu because of how challenging it was,” says Hamuy. “So I decided to dedicate myself full time to the sport.”
Hamuy, who has a Black Belt in No-Gi and is a World Champion, will compete in the upcoming IBJJF World Master Jiu-Jitsu Championship September 3-5 at Las Vegas Convention Center. The road to a black belt is often grueling, a journey Hamuy describes as rewarding despite the inevitable obstacles. “If I had to go back, I would do it all over again without hesitation,” she reflects.
Her commitment culminated in a career-defining moment last December: winning the World Championship. Having chased that title for nine years, Hamuy notes that the previous near misses served as essential fuel. “Every time I came close and didn’t achieve it, it became fuel to keep pushing harder,” she says.
Hamuy’s success is built on an ironclad routine. Her physical preparation includes daily BJJ training supplemented by strength and conditioning three times a week. However, she stresses that the mental game is equally vital.
Beyond physical sparring, she incorporates weekly sessions with a mental coach, alongside daily practices of mindfulness, visualization, and journaling. “No matter how much we train, if we don’t master our mind, we won’t be able to perform well,” she explains. “Mastering these things from white belt has given me a lot more success.”
As a prominent female athlete in a sport often dominated by men (BJJ is dominated by 85% male athletes), Hamuy admits the landscape presents unique challenges. She acknowledges that women in the sport are often held to higher standards of intensity and character. Yet, she remains optimistic, highlighting the supportive community she has built.
“I have been fortunate to find many friends, teammates, and mentors who respect me for what I know and who I am,” she explains.
Hamuy moved to California two years ago, which was a catalyst for her recent growth. Training alongside other high-level women has been crucial to her evolution, allowing her to step onto the competition mats with unwavering confidence.
Now, as a certified IBJJF referee and an athlete at Academy Worldwide LLC, Hamuy continues to train and compete at the highest levels of Brazilian Jiu-Jitsu, driven by the belief that the harder the training, the stronger the performance on competition day. That mindset has not only earned her gold medals but also reinforced her standing as a respected competitor in the global BJJ community.
For Hamuy, the philosophy is simple: the harder the training, the more prepared the athlete—a mindset that has not only earned her gold medals but solidified her role as a respected competitor in the global BJJ community.
