Legendary Brazilian Jiu-Jitsu coach John Danaher has offered profound insights into what he believes is the most valuable aspect of practicing the martial art: the ability to solve problems under pressure.
“For an individual, the greatest gift that I think they get from jiu-jitsu is the idea of solving problems under stress,” Danaher explained. “Every second of every match you’re ever involved in in jiu-jitsu is an attempt to solve the problem that my opponent is presenting to me.”
What makes jiu-jitsu unique, according to Danaher, is the dynamic nature of these challenges. Unlike static problems such as mathematical equations, jiu-jitsu practitioners face constantly evolving situations against an intelligent opponent actively working to counter their efforts.
“In jiu-jitsu, the problems aren’t static, they’re dynamic,” Danaher noted. “Worse than that, not only are they dynamic, I’m dealing with a cognizant thinking opponent which is trying to defeat everything I’m trying to do to them. So with each second the problem changes.”
This perpetual problem-solving environment creates what Danaher describes as an addictive quality to the sport.
“That’s why it has such an ability to hold people and addict people, because really the problems never get solved. Your opponent keeps getting smarter day by day.”
These insights come at a challenging time for Danaher himself, who recently underwent his second hip replacement surgery. The renowned coach shared the news on social media, revealing the extent of his physical struggles.
“Today I went into surgery for my second hip replacement. I’ve had severe physical issues my whole career due to a crippled leg suffered from an early age,” Danaher stated.
He added that he had delayed this procedure for approximately four years, particularly after his team’s transition period following their departure from Puerto Rico.
“I was going to do [it] after we left Puerto Rico but when the team broke up I had to delay it in order to be able to build a new team. Now it’s time as I’m struggling to even walk and perform basic functions, let alone jiu-jitsu,” he explained.
Despite these personal challenges, Danaher remains focused on the transformative power of jiu-jitsu training. He emphasized how the skills developed on the mat translate to everyday life.
“We live in a stressful world where usually most things are stacked against us. Just a simple act of getting to work some days can be tough,” Danaher observed. “Your ability to maintain a calm even mind and solve problems as they come flying at you with potentially bad consequences—that’s a very, very useful attribute for any human being to have.”
This period marks a significant transition for Danaher and his New Wave Jiu-Jitsu team. His star pupil Gordon Ryan, widely considered the greatest no-gi grappler of all time, is reportedly stepping back from competition due to health issues. Meanwhile, team member Nicholas Meregali is recovering from shoulder surgery.
While Danaher faces a recovery period that will keep him off the mats temporarily, he remains optimistic about his continued contribution to the sport.
“I will be out of action for a while but I believe I can still be a help conceptually until I can get active again,” he stated.
Through his personal journey of overcoming physical limitations, Danaher embodies the very philosophy he teaches—facing challenges with resilience and finding solutions even under difficult circumstances.
