Quick Definition
Hapkido in MMA refers to the use of hapkido, a Korean martial art built on joint locks, throws, and circular kicks, by mixed martial artists. It is rarely a fighter’s primary base, though several UFC competitors trained in hapkido before moving into the sport.
What is hapkido in MMA?
Hapkido is a Korean martial art founded in the mid-20th century by Choi Yong-Sul, who blended Japanese Daito-ryu aiki-jujutsu with native Korean kicking and striking. The name breaks into three parts: hap (harmony or coordination), ki (energy), and do (the way). In practice it teaches joint locks, throws, and dynamic kicks, with a focus on redirecting an attacker’s force rather than meeting it head-on. Its original purpose was self-defense, not sport.
“Hapkido in MMA” describes how that self-defense art overlaps with cage fighting. It is not a style anyone builds a modern MMA game around. Its footprint in the sport comes almost entirely from fighters who trained hapkido first, then added the wrestling, boxing, and Brazilian jiu-jitsu that MMA demands. Because hapkido already blends striking with grappling, some schools market it as an early “mixed” martial art. That framing explains why the term surfaces in MMA conversations at all, even though hapkido and modern MMA grew up separately.
How hapkido appears in the cage
A fighter with a hapkido background does not look obviously different from any other well-rounded competitor, because hapkido gets absorbed into a larger toolkit. A few of its habits still carry over.
The clearest is kicking. Hapkido trains a wide range of kicks, and that early exposure can show up as comfortable, varied kicking at range. The art’s circular movement, the idea of stepping off-line and redirecting rather than trading straight punches, also fits neatly with modern striking footwork.
Hapkido’s throws and standing joint control overlap with judo and clinch work, so a practitioner may flow into a throw or off-balance an opponent smoothly. What tends not to appear is hapkido’s signature self-defense material, its wrist and finger locks and its weapon defenses. Those were built for subduing an untrained attacker, not for a gloved opponent inside a cage.
Why hapkido is rarely a primary base in MMA
Three things keep hapkido on the margins of competition.
The first is the rulebook. Much of hapkido’s grappling targets small joints, and the Unified Rules of Mixed Martial Arts, adopted in 2000, ban manipulation of the fingers and toes outright. Wrist locks and ankle locks stay legal, since the wrist and ankle are not classed as small joints, though wrist locks are notoriously hard to finish on a taped, gloved, sweaty hand. A large slice of hapkido’s joint-lock curriculum cannot be used the way it was taught.
Weapons are the second problem. Hapkido devotes real training time to the cane and short staff, and none of that has a place in an unarmed sport.
The third issue is the ground. Most hapkido schools train to stay standing and avoid the mat, so they spend little time on bottom-position escapes or submission defense. Ground skill has been non-negotiable since the earliest UFC events, which is why a hapkido stylist aiming for MMA almost always cross-trains Brazilian jiu-jitsu to fill the gap.
Fighters with a hapkido background
The sport’s clearest hapkido connection is Robert Whittaker, the former UFC middleweight champion and the first Australian to win a UFC title. Whittaker earned a first-degree hapkido black belt as a teenager, training under coach Henry Perez. When Perez converted his hapkido gym into an MMA gym, Whittaker followed the sport there and never went back.
The other well-known name is Chan Sung Jung, “The Korean Zombie.” His aunt enrolled him at a hapkido gym around age 14, and he built out from there into kickboxing, judo, and Brazilian jiu-jitsu. Jung later landed the first twister submission in UFC history and challenged José Aldo for the featherweight title in 2013.
Wikipedia documents ten mixed martial artists with a hapkido background, among them 1990s UFC competitor Patrick Smith and Denis Kang. In each case hapkido was a starting point, not the style they fought under.
| Fighter | Hapkido credential | MMA note |
|---|---|---|
| Robert Whittaker | First-degree black belt | Former UFC middleweight champion |
| Chan Sung Jung (“The Korean Zombie”) | Trained from around age 14 | First twister submission in UFC history |
| Patrick Smith | Hapkido black belt | Competed in early-1990s UFC events |
Hapkido vs. aikido
Readers who meet hapkido often confuse it with aikido, and the two do share a root: the founders of both studied within the same Daito-ryu aiki-jujutsu lineage in Japan. The family resemblance shows in the joint locks, throws, and circular movement common to each.
| Hapkido | Aikido | |
|---|---|---|
| Country of origin | Korea | Japan |
| Founder | Choi Yong-Sul | Morihei Ueshiba |
| Shared root | Daito-ryu aiki-jujutsu | Daito-ryu aiki-jujutsu |
| Kicks | Yes, extensive | None |
| Orientation | Defensive and offensive | Primarily defensive |
The split comes down to intent and range. Aikido is almost purely defensive and uses no kicks. Hapkido keeps that defensive core but adds offensive striking and a wide kicking arsenal, which makes it the more combative of the two. That striking element is also part of why hapkido, and not aikido, sometimes turns up in a fighter’s background.
Frequently Asked Questions
Is hapkido effective in MMA?
On its own, rarely. Its kicks and circular movement transfer well, but its joint-lock and weapon work mostly falls outside MMA rules. Fighters who use it treat it as one layer beneath wrestling, boxing, and jiu-jitsu.
Which UFC fightedrs trained in hapkido?
Robert Whittaker holds a first-degree hapkido black belt, and Chan Sung Jung, “The Korean Zombie,” started out in a hapkido gym. Wikipedia documents ten MMA fighters with a hapkido background.
Is hapkido the “original mixed martial art”?
Some schools use that label because hapkido blends striking, kicking, and grappling. It predates modern sport MMA and was designed for self-defense, so the two are related in spirit but developed on separate tracks.
Can you use hapkido joint locks in the UFC?
Large-joint locks, yes. Manipulating the fingers and toes is banned under the Unified Rules, and many hapkido controls target exactly those small joints, which makes them illegal in the cage.
