I found this post from another and figured I'd chime in. I am by no means what so ever a student of systema, but I aspire to be. My teacher, is working with a great systema teacher, actually a very gifted man in all ends of Martial Arts, he may offer classes at the Dojo.
I witnessed systema first at a Kempo seminar in Cape Cod, MA. One of the teachers there was Arthur Sennott, of Systema: New England:
http://russianmartialart.org/ . Sorry to say that his videos aren't working right now, but you can use his site to jump to another or even email him, from what I have seen in him, he is a fountain of knowledge and is willing to teach anyone who listens.
At the seminar Mr. Sennott taught us some basic systema techniques. Some may say that training slows down and prepares the victim/attacker from true usage, but I will say this is not so in all cases. During the seminar I work with a CCMAA systema student. He was my size, and looked as though he would clash it out with me. We both tried to out muscle each other all day. You know what, the moves work! Not even one hour of practice and the simple muscle manipulation work every time.
Now, Arthur didn't do any chi like yoda move that was shown in the video, but there is something to the way Mr. Sennott threw his punches. When he hit you, it was like you got hit by a car. I know first hand as I volunteered to take some punches. He left bullseye like rings on my stomach in shades of blue, black, green and yellow and the blow knocked me back a couple of inches, sending pain to my groin up to my chest and arms!
Systema is no joke and what amazes me even more, is that its conditioning appears to be next to nothing. His student Matt (we all feel bad for Matt), took at least one, to two hundred punches throughout the day, which led to Arthur asking for assistance. But Matt took it! And stood right back up. I know, that Arthur didn't hit me as hard as he hit Matt. With me, it hurt and I took about ten, probably could have toughed out another five, and macho'd another five because puking. When he hit Matt, you saw kidney shots, liver shots, and even hyper-extended elbows.
Do yourself a favor, if you are really serious, schedule a seminar! Must see for yourself.
