How much should I pay for Kali classes or Krav maga?

Hyung very important. You could say it is a cornerstone. It has multiple values.

It teaches more than words can say. There values are so many I keep learning new ones all the time. Far from just a good warmup and cardio.

There are combinations, angle of defense and attack. Foot placement, grappling, defense against multiple attackers. Defense against weapons.

The list goes on. Even so called 'hidden techniques'. So valuable that several martial arts teach that once you reach a certain Dan you relearn all the forms at a different level and concept.

Since even the basic forms have multiple meanings, interpretations and applications. About 6 months ago my martial art school hosted in conjunction with our anniversary a seminar with other styles on application of hyungs/kata. Which can change your outlook on the indispensable value of them.

Very valuable and important.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
