Whatever Martial art, combat system, hand to hand etc you need a good and skilled instructor, without him or her then, to be far you may be wasting your time.
As the National Security College's CQC/self defence instructor I teach what works but in a way that people can understand and go away and develop the skill needed to refine the techniques.
I have an extensive Martial art career, training for 35 years, and what generally people want for lets say security training is ..the dirty fighting techniques. The stuff that works NOW, can be applied SIMPLY, EFFECTIVELY and part of our bodys natural reaction to adverse situations. This is what I teach at the NSC
www.nsc.sc plus other 'goodies'.
I have trained and taught all over the world and continue to learn from my teacher in Japan where i go ever year...I say this because at the age of 45 i still want to continue to learn and refine.
In addition to my 'Jap slapping' antics as my friends at the NSC would say, I was also one of the first UK KM (Krav Maga) Instructors back in 1989, I learnt this in Israel when very few outside of Israel knew about it.
If your interested, in what and how I teach effective self defence for CP at the NSC then please PM me.
But as we everything we do regarding skill I will leave you with this little quote I heard " an amateur practices till he gets it right, a profeesional pratices till he doesnt get it wrong"
Whatever system, course etc learning someting in 1, 2 or 3 days dont make you an expert.
