they actually advocate using just your arm while punching instead of putting your body into it as a method of power generation
anyone with a basic knowledge of physics could tell you otherwise[/QUOTE]
the way i have seen it explained is that a human arm is around 15lbs. hit someone with a 15lb lump of wood/rubber etc and there would be no problem in causing some serious damage.
all martial arts have their frauds. Systema is one of them. if you want an understanding of the human psyche in relation to 'chi blasts' etc. then watch Derren Brown's show 'The Heist' it will all become very clear, very quickly
Ryabko was a Special Forces Op. and it would be fair to say that he will know how to handle himself. Val Riazanov is a heavyweight boxer and a judo blackbelt - he also is a 'master' of systema. i think the issue is that systema principles are taught in a weekend workshop then the participants then go on to teach
My daughter has just learnt to bumshuffle around a room two weeks ago, funnily enough i havent sent her out to teach other children how to move....
think about it.
TRUE systema seems pretty authentic to me.
