“Zentensity” is a concept coined by Bill Viola Jr. that describes a profound connection between the body, mind, and spirit empowering individuals to transcend perceived limitations. At its core, it’s about pushing yourself to the limit, then gaining an extra inch nobody thought was possible! This state of being is pushing past your potential and transcending into a warrior. It represents the fusion of intense focus and Zen-like calm, enabling exceptional performance and personal growth. Even during high-stakes moments, athletes often report feeling calm or at peace. We call this the “ZONE.” Time seems to slow down in this rare neurological state — where body and mind synchronize, and the conscious mind steps aside for pure performance. Movements feel effortless and automatic. Distractions disappear, and the athlete becomes fully absorbed in the moment. Weakness becomes your weapon, and pain becomes your pleasure. Ultimately its about “will over skill.” This is a mental battle within; fueled by a desire to conquer what your peers think is possible.
While especially relevant in martial arts—where mental strength and physical skill are equally vital—this mindset also applies to overcoming challenges in everyday life. “Zentensity” is a Sensei Viola’s term to express a powerful martial arts mindset that blends his 6-Samurai mindset “way of life” —one that blends Zen philosophy with intensity of purpose. It’s more than just a buzzword; it represents a lifestyle, a training philosophy, and a mental framework that can be applied both inside and outside the dojo. The term became part of martial arts vernacular with the release of the COMMONSENSEI book series, and gained further recognition when Viola’s daughter, Gabby, made front-page news in Pittsburgh for her battle with inflammatory bowel disease. Zentensity emphasizes syncing the mind and body to perform at peak levels—especially in high-stress or high-stakes moments. Along with Kaizen methodology, the two are deeply complementary philosophies—when practiced together, they create a powerful framework for personal growth, martial arts training, and life mastery.
SENSEI SAYS: “Zentensity” is a portmanteau:
Zen – The ancient Buddhist practice focused on mindfulness, presence, and inner peace.
Intensity – The drive, energy, and commitment to push limits and overcome adversity.
When it clicks! Together, the word reflects a synergy and balance: of mind body and spirit to push past your perceived potential.
CommonSensei: Viola brands himself as a “Common + Sensei”—a life mentor combining everyday wisdom (“common sense”) with traditional martial-arts “way of the teacher” Zentensity was formally introduced in the Common Sensei book series. In it, Viola distilled decades of lessons from the dojo into bite-sized philosophies that applied to life, leadership, learning, and legacy. The concept of Zentensity became a cornerstone of his curriculum—especially for young readers navigating pressure, anxiety, and setbacks.
Shihan always told me how good I could be, but that day I became great. I’d given 99% a thousand times, but never went full throttle. The endless harping, yelling, and screaming: “harder, harder, harder” lit a wick that burned slowly. Then, without any warning about half way through Bassai Dai — ignition! I exploded in martial bliss. Bruce Banner became the Hulk, and I saw my true potential for the first time. I was “aware” of what Bill Viola Jr. was capable of. My nostrils flared as the clouds parted. It scared the bejesus out of me; frightening and glorious all the same. Yin to the yang! Up until this point I was a hard worker and winning, but still a mere mortal. Finding “ZENtensity” was immortal. It was the spark Shihan had been longing for, and his face gleamed like the 4th of July — an expression forever tattooed in my mind. That image is a permanent reminder of my breakthrough to the dark side of the moon. It’s since become my mission to help other’s reach for the stars. READ MORE

Bill Viola Sr. instilled Zentensity in his son, Bill Viola Jr., not through lectures or lessons—but through example. He embodied the balance of Zen-like calm and intense grit every day, creating a blueprint for his son to follow. Zentensity—the fusion of inner peace and relentless drive—wasn’t a word back then, but it was a way of life in their dojo.
Bill Sr. didn’t protect his son from difficulty. He believed in letting him sweat, stumble, and stand back up. Every setback was a stepping stone. Through countless hours on the mat and moments of doubt, Bill Jr. absorbed the mindset: “Push past the pain. Find your center. Don’t quit.”
It’s not about being perfect overnight. It’s about embracing the grind (Kaizen) while keeping your mindset sharp and steady (Zentensity), so you’re always growing and ready when the moment comes.
Kaizen (改善) means continuous improvement—the idea of getting 1% better every day. It’s a long-term mindset focused on small, consistent actions that lead to big change over time.
Zentensity is the intensity of presence—calm but powerful energy that keeps you focused and determined in the moment. It’s what pushes you forward when Kaizen feels slow or difficult.
Kaizen is the path; Zentensity is the pace.
Kaizen is “brick by brick”; Zentensity is the fire that lays each brick with purpose.
Kaizen builds habits; Zentensity powers through challenges.
Train with Kaizen. Perform with Zentensity!
1. Zentensity: Gigo’s Inner Fire
Zentensity is Gigo’s mental edge—the moment where his mind, body, and spirit align under pressure.
At the dojo, Gigo learns that martial arts isn’t just about punches or kicks—it’s about harnessing focus, resilience, and emotional control.
Whether breaking a board or bowing to a partner, Gigo trains to stay present, purposeful, and powerful. This calm intensity defines his black belt mindset.
“Zentensity means I don’t quit when it gets tough. I center myself, breathe, and go beyond.” – Gigo
Kaizen (改善) means continuous improvement—and Gigo lives by it.
At the dojo, progress is never about being perfect—it’s about being 1% better every day.
Each technique, kata, or sparring match is a step forward. Gigo journals his small wins, corrects his form, and helps others grow too.
Bill Jr. explains, “Gabby has what I call ‘zentensity,’ a body-mind connection that pushes past what you thought was possible. That is a term he coined the book “CommonSensei.” It’s a mindset that leaves nothing to be desired – 100% effort. Outside the ring she is shy and reserved. Inside the ring, she transforms into tiger.” “Zentensity” is what has led her to this moment. She chose her birthday to partake in the final most difficult part of her young martial arts journey. The shodan test (1st degree black belt) is a grueling mental and physical challenge. It is a four-month process that encompasses learning a vast history of martial arts, Japanese terms, hundreds of techniques, endless combinations, self-defense maneuvers, and physical endurance. Many organizations award black belts in a short window of time, but Allegheny Shotokan is “old school” and upholds the strictest of standards. The Viola family including Gabby is held to a higher standard. The final exam represents nine years of training, thousands of hours of practice, and hundreds of competitions. Gabby says, “I wanted to be like my Dad. My black belt is better than any trophy.”
“Zentensity is forged, not found.”
When achieved, Zentensity is a state of peak personal alignment—when your mind is calm, your body is prepared, and your potential is unlocked through intentional focus. It’s the moment when a person stops holding back and unleashes their full capacity, not through chaos or adrenaline, but through centered energy. Something just clicks, and you are in the zone!
You must practice calm intensity in tough moments:
When you’re tired.
When you’re frustrated.
When you want to give up.
That’s where real Zentensity is born—when you stay composed and committed under pressure.
A North Huntingdon girl has earned her first-degree black belt in karate at age 11, persevering through an inflammatory bowel disease that can be debilitating.
Gabriella “Gabby” Viola, 11, the daughter of Jennifer and William Viola Jr., became the youngest holder of a black belt among those who have trained at Allegheny Shotokan Viola Karate Dojo, a North Huntingdon karate school operated by her father, Bill Viola Jr., and founded in 1969 by her grandfather, Bill Viola Sr. She earned her black belt on Aug. 17, which was her birthday.
“Gabby has what I call ‘zentensity,’ a body-mind connection that pushes past what you thought was possible,” her father said.
Having a black belt runs in the family. Both her father and grandfather have their black belts, as well as four of her aunts — Addie, Jacque, Ali and Joce Viola. Fewer than 100 people who have trained at Allegheny Shotokan over the past 50 years have earned a black belt, her father said.
“I wanted to be like my dad. My black belt is better than any trophy,” said Gabby, who shared the honor with six teammates who also took the test.
The youngster, a fifth grade student at Norwin’s Hillcrest Intermediate School, has been “kicking before she could walk,” her father said.
“She literally grew up in the dojo,” said her mother, Jennifer, of the karate school. “It was like her playground.”
Gabby, who trains three or four times a week, said she underwent a six-hour test in which her skills were judged to earn her black belt. She had gone through a four-month process which involves learning the history of martial arts, Japanese terms, hundreds of techniques, endless combinations, self-defense maneuvers and physical endurance.
Gabby has accomplished this while suffering from irritable bowel disease, her father said. It is an incurable form of colitis, an autoimmune condition that attacks the healthy tissue in the intestine. She has dealt with bouts of severe bleeding, dehydration, abdominal pain, cramping and joint and skin inflammation, her father said. She has had to endure a number of setbacks and emergency room visits.
“Martial arts teaches perseverance, and she decided that nothing would stop her from earning her black belt,” her father said.
She undergoes monthly infusions of medication at Children’s Hospital in Pittsburgh as part of the treatment regime that includes medical trials, diets, medication, steroids, tests and therapy.
Despite the risk of having a flareup of major symptoms after a period of remission, Gabby has competed nationally. She won a gold medal at a World Kendo Championship’s National Championships for martial arts in 2019 and earned a spot on Team USA. She has been recognized as a five-time state champion and ranked first in the North American Sport Karate Association for black belt sparring in 2020.
As for earning her second-degree black belt, Gabby said she must wait until she is 16 to take that test.
She is joined in her family’s love of the sport by her 4-year-old brother, William Viola IV, who trains in the “Nursery Ninja” program and holds a yellow stripe belt.
Gabby is an ambassador for the sport, promoting it to other youngsters.
“They should try it. It is fun, and it is good exercise,” Gabby said.
