4D Combat was developed by Guru Bob Breen from the two amazing arts of JKD and Kali.
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.


“Adapt what is useful, reject what is useless, and add what is specifically your own”- Bruce Lee
He made the decision that 4D Combat would concentrate on stand up fighting.

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

  • Striking

  • Clinching

  • Weapons

  • Group Attack
