Sure you can train in everyday clothes, practice illegal in sport techniques but these small differences are just chump change.
People that are into the tactical training often times differentiate themselves from other martial artists with strategies and tactics. But once again these thoughts are just another way of saying principals and concepts. People often times think and talk way too much and get lost in theory.
The way I set the foundation for realistic training is simple. One word, failure.
If what you do is based on success then maybe your expectations are too high, your living in a fantasy world, reality will come knocking on your door with a sledge hammer.
But if what your doing is based on the cold hard lessons of failure then your much more grounded to reality.
How do you know if your based on success or failure?
Often times technique training relies on success. Do you learn a lot of techniques? Do you practice tons of techniques? Do you have tons of options in your arsenal? Do you do a lot of demonstration type practice, where one person freezes for the other to execute the technique? Often times this kind of training also looks really cool because basically it's choreography.
Now on the other hand, training based on failure is much more rudimentary. You may not be able to finish the fight, so you gotta prepare for a battle of attrition, let's start with cardio conditioning. You may miss so let's work on combos over and over. Like it or not, you may end up on the ground so let's start wrestling. There is going to be more live training such as sparring, working focus mitts, shadowboxing, and really working on the application of technique, making it work against a resisting opponent, an opponent who has caught on to the move, rather than accumulating tons of technique.
So this is another reason why I developed Knifeboxing. And I hope you can see that Knifeboxing is not just holding a knife and pretending to be a boxer.
All this being said, I'm not here to bash any style or anyone. Technique training is 100% necessary. We did it in Brazilian Jiu-jitsu, when I trained in Wrestling, Boxing, Muay Thai, Savate, Judo.
I bring this subject up so you know why I do things the way I do.
I like the simplicity of Knifeboxing because remember a good way to show someone nothing is to show them everything.
