What is 4D Combat?

4D Combat was developed by Bob Breen from the two amazing arts of Jeet Kune Do (JKD) and Kali.

Guru Bob Breen is a master martial arts instructor with over 50 years' experience at the highest level. 

Both JKD and Kali are amazing arts but how do you master both of these in one lifetime?

Bob wanted to create a simpler model; something that would work for normal people yet have all the depth of the arts from which it was derived.

Lots of JKD and Kali techniques were similar so the first thing Bob did was to cut out the duplicates and then he prioritised the things that really happened in a street fight or competition. His aim was to keep the art, but prioritise the function.

He made the decision that 4D Combat would concentrate on stand up fighting - where all fights start and most end.

Why is it called 4D Combat?

The name 4D Combat came about as the system comprises the four dimensions of stand up combat:

  • Striking
  • Clinching
  • Weapons
  • Group Attack

Bob’s aim with 4D Combat is for people to achieve mastery in their lifetime and on their own terms; the art has to suit you.

  • It has to be simple
  • It has to be truthful
  • It has to be instinctive
  • It has to work - whatever comes up!
  • And it has to be tested - so you believe in it,  and know that it works.

Therefore in 4D Combat, the same game formats or templates are used, whatever you’re doing. This makes you faster, both mentally and structurally.

“Whilst they’re deliberating, you’re obliterating.”
