Krav Maga vs. Jeet Kune Do
Quick answer
Krav Maga and Jeet Kune Do have no documented mutual relationship and share only the concept of simultaneous defence and attack. Krav Maga is an Israeli self-defence system with stress scenarios, ground fighting and defence against weapons, and JKD is an approach that Bruce Lee named in 1967 and built on Wing Chun, boxing and fencing. Neither has sport competitions and neither is Olympic.

History and relationship
We have not found a direct relationship between Krav Maga and Jeet Kune Do. Krav Maga was developed by Imi Lichtenfeld from European boxing, wrestling and street fighting, and JKD was named by Bruce Lee in 1967 in the USA. Both arts describe simultaneous defence and attack, but this is a coincidence of concepts, not a documented influence.
- 1944: Lichtenfeld teaches wrestling, work with a knife and defence against it in the Hagana.
- 1948: Lichtenfeld becomes chief instructor of physical training and Krav Maga in the IDF.
- 1959 or 1960: Lee opens the first Jun Fan Gung Fu school in Seattle, in 1964 a second in Oakland with James Yimm Lee.
- 1967: Lee gives the system the name Jeet Kune Do and opens a third institute in the Chinatown of Los Angeles.
Technique
- Punches, forearm and hammer-fist strikes, elbows, knees and kicks.
- Targets such as the eyes, throat, groin, ribs and liver.
- Locks, throws, chokes and ground fighting.
- Defence against a knife, a stick and a firearm, improvised objects.
- Four ranges: kicks, punches, trapping and grappling.
- Stop hit and stop kick taken from fencing.
- Kicks to the shins, knees, thighs and midsection, no higher.
- Centreline and trapping from Wing Chun.
Krav Maga attacks with simple repeatable strikes until the opponent is unable to fight. JKD waits for the opponent’s movement to attack and intercepts it, and sees simultaneous cover and strike as a step before the stop hit. The sources do not give JKD defence against weapons, while Krav Maga practises it as part of the syllabus.
Training
| Krav Maga | Jeet Kune Do | |
|---|---|---|
| Pillars of teaching | techniques, stress drills, scenario training, sparring and slow-fight | forearm conditioning, wooden dummy, conditioning exercises |
| Fighting in training | in some organisations up to G2 only slow and light, then with protectors | we have not found sparring or pad work |
| Fitness | a DVD lesson: 78% of maximum heart rate (ACE) | Lee’s own programme: strength training, running, stretching, exercises after Great Gama |
| Frequency | IKMF Netherlands: 9–18 months twice a week to the first test | we have not been able to document it |
Krav Maga builds a lesson around scenarios under stress. For JKD the sources describe Lee’s own training, and we have not been able to document the structure of a lesson in today’s schools.
Progression and ranks
| Krav Maga | Jeet Kune Do | |
|---|---|---|
| Grades | IKMF patches P, G, E and Master, elsewhere belts after judo | instructor certificates, we have not found a belt system |
| Before the first test | IKMF Netherlands: at least 45 lessons | we have not been able to document it |
| Path to instructor | IKMF Netherlands: from G5 to E1 only with the CIC course | Lee personally certified Taky Kimura, James Yimm Lee and Dan Inosanto |
Taky Kimura held the 7th grade of Jun Fan Gung Fu. We have not found a scale that would apply across the JKD lineages. In Krav Maga every organisation has its own system, and in IKMF Netherlands part of the grades is tested by one’s own instructor and part centrally.
Physical load and risks
- 946 injuries of 916 IDF soldiers from training (Farkash et al., Military Medicine 2017): mostly mild, most often fingers, hands and wrists (31%), head and neck insignificant.
- 109 questionnaires of civilian practitioners (Yaacobi et al., Cureus 2024): most often lower limbs (38.5%), the data partly contradict each other.
- We have not found a study of injuries in JKD.
- We have not been able to document training against resistance, sparring or injuries in JKD in the sources.

Self-defence
- Punches, kicks, locks, the ground, weapons and verbal de-escalation.
- 360-degree defence and scenarios with several attackers.
- The partner’s resistance in some organisations limited up to G2.
- Lee rejected prearranged forms as ineffective in chaotic self-defence.
- Techniques are to be judged by their use in a real fight.
- The sources do not describe the degree of resistance in training.
Krav Maga developed in the training of the Hagana and the IDF and has a self-defence syllabus for the army, the police and civilians. JKD describes a principle for choosing techniques, not a self-defence syllabus. We have not found a study of effectiveness against a real attack for either of them.
Practical use
| Krav Maga | Jeet Kune Do | |
|---|---|---|
| Study | 16 female university students (PeerJ 2020): 15 minutes of instruction improved the straight punch and the defensive kick | we have not found a study with numbers |
| Fitness load | a DVD lesson in 16 people (ACE): 78% of maximum heart rate, 616 kcal | we have not been able to document it |
| Professional use | Israeli army and police, since 2008 also an airborne school in Upper Bavaria | we have not found police or army training |
| Film | we have not been able to document it | Chad Stahelski, a student of Dan Inosanto, fight choreographer and director |
The Krav Maga studies concern small groups and a single lesson, and for JKD they are missing entirely. No general conclusion about suitability can be drawn from them.
Competition
| Krav Maga | Jeet Kune Do | |
|---|---|---|
| Sport competition | does not exist | we have not found competition rules for JKD |
| Other forms | IDF since 2013 an annual competition, rules not documented | not applicable |
| Fighters in other competitions | Moti Horenstein at UFC 10 and UFC 14 | Joe Lewis, Lee’s student, competed in karate and in PKA full contact |
| Olympic programme | no | no |
Gear and costs
| Krav Maga | Jeet Kune Do | |
|---|---|---|
| Clothing | IKMF for tests a grey T-shirt and black trousers with a grade patch | we have not found prescribed clothing |
| Equipment | mouthguard, groin guard, shin guards, boxing or MMA gloves | wooden dummy and aids for forearm conditioning |
| Weapons | defence against a knife, a stick and a firearm | not documented as part of the system, Lee learned nunchaku and the stick from Inosanto |
| Relative costs | medium | cannot be determined |
Availability and organisations
| Krav Maga | Jeet Kune Do | |
|---|---|---|
| Organisations and lineages | IKMF, KMG, Krav Maga Worldwide, IKMA | Original (Jun Fan) JKD, JKD Concepts, Bruce Lee Foundation |
| Recognition of grades when moving | we have not found recognition between organisations | we have not found a single governing body |
Krav Maga split in succession disputes after 1998. Lee did not formally codify JKD. Original JKD teaches what Lee taught, and JKD Concepts develops it with grappling, kali and eskrima.
Switching and combining
- Simultaneous defence and attack remains, JKD takes it as a step before the stop hit.
- Kicks according to JKD only to the shins, knees, thighs and midsection.
- Add trapping and work with the centreline.
- Postpone defence against weapons and scenarios with several attackers, the JKD sources do not describe them.
- The habit of drawing on several arts remains, Krav Maga is also eclectic.
- Add stress drills and scenario training.
- Add defence against a knife, a stick and a firearm.
- Expect tests and patches or belts, depending on the organisation.
On the left the transition from Krav Maga to JKD, on the right from JKD to Krav Maga. We have not found a figure who is documented as combining both arts.
Philosophy
- Motto according to the IKMF: So that one may walk in peace.
- Avoid violence, attack only as a last resort.
- Zen, Confucianism and Taoism, principles of effectiveness, directness and simplicity.
- The taijitu symbol with the sentences Using no way as way and Having no limitation as limitation.
- Lee’s sentence Be formless, shapeless, like water.
Both arts reject ornamental movement and measure technique by effectiveness. Krav Maga comes from training for the army and the police, JKD from Lee’s philosophy with roots in Zen and Taoism.
Forms and terminology
Neither art has routines, each for a different reason. IKMF Netherlands describes Krav Maga as a functional system without ornamental movements and stylised forms. Lee regarded prearranged forms and patterns as limiting and ineffective, but from Wing Chun the wooden dummy (Mook Yan Jong) remained in JKD to simulate an opponent.
Training culture
- At the IKMF a patch on the trousers, elsewhere belts after judo.
- A military and police branch alongside the civilian one.
- We have not been able to document the salute and the form of address of the instructor.
- Lee as Kato in the series The Green Hornet (1966), the first fictional character with JKD.
- Enter the Dragon was released six days after Lee’s death in 1973.
- JKD in the series Arrow, in the anime Cowboy Bebop and in games such as Tekken and Street Fighter II.
Common misconceptions
- Mistake: JKD is a fixed style. Lee later regretted the name because it suggested fixed boundaries, and he described JKD as a style without a style, a process and not a product.
Which to choose
Frequently asked questions
Does Krav Maga come from Jeet Kune Do, or the other way round?
We have not found a direct relationship. Lichtenfeld taught in the Hagana from 1944, Lee named JKD in 1967 and drew on Wing Chun, boxing and fencing. A coincidence in the principle of simultaneous defence and attack does not document an influence.
Does JKD have belts?
We have not found a belt system. Lee personally certified three instructors, Taky Kimura, James Yimm Lee and Dan Inosanto. At the IKMF Krav Maga uses patches P, G and E, elsewhere belts after judo.
Can one compete in either of them?
Neither has a sport competition and neither is Olympic. Since 2013 the IDF has held an annual competition in Krav Maga, and we have not found competition rules for JKD.
