When I started CMA, the big thing was stance training. The teacher would make people hold stances (horse, bow and arrow and others) for long periods of time. We were told that this was a requirement and that it was important because without a solid stance the techniques wouldn't work and we would "have no root".
But when the first UFCs happened, this idea seemed to get destroyed very quickly. What good did having a "solid root" do when a BJJ player or wrestler could take you to the ground. No-one's "root" stopped a takedown!
And how about when we saw muay thai guys, who spend NOT ONE SECOND doing stances ... and yet pulverizing opponents. They certainly didn't lack power or stability despite never having done a horse stance in their life!
Do MMA schools actually make students do any stances?
Now that students see that they can get the same fighting skills in MMA, without having to "prove their dedication" by holding painful horse stances, does this mean that kung fu teachers will no longer be able to make students do this?
Was the whole thing simply a scam, designed to fill up hours of class time without having to teach much?
This comes down to the underlying problem of the internal external thing even though you could make a good case for stance training being either internal or external.
The real problem is that most people starting out (like you, galo) don't really know what goes into making their training work and so they have a problem dovetailing that with being honest with what they want. This mixed with the assumption that you can go beyond "styles" and just pick and choose what you want will give youi the question you just asked.
This is near and dear to my heart, because i have a pretty good idea of what I want and how it works and a lot of it revolves around stance training.
So, what does stance training give you? Depending on how it's taught it will give you different things, right?
If you train it the longfist way it'll have a large endurance factor and it will place a large emphasis on the yogic body opening component. Is it important to you being able to fight? It depend on what you want. It gives you certain attributes that are part of "gung fu". Gung fu is about eating bitter to gain an attribute...so you can drop and still fight but you won't have gained the specific atrributes gained from opening that part of the body in that specific way...regardless of what style you are practicing.
If you do your stance training the internal way for long periods of time (this includes walking) then you are jacking up the neuromuscular/mindbody aspect of the training where you are burning those differnt shapes and stances and transitions into your body/mind/memory....the more dynamic and fullfilled you want that attribute to be is once again dependent on how much sweat you put into it. Do you need that to fight...not necessarily, but if you want those attributes to be part of your fighting style then yeah, you need to put in the time.
I'm having to go back and eat bitter on all that stance training stuff because I got too lazy too early by myself....and it's a pain in the ass, but I'm going back and doing it because I want what you get out of that. If you don't see having those attributes available to you as being as important as being able beat the fuck out of a heavy bag with your thai kicks then don't.
Best,
