If you can get all 3 Systema Spetsnaz seminar DVDs - get them!!! If not, choose this one! Six hours of hand to hand combat training were combined in 2 hours, so you will have to practice and watch it again and again. And it worth it!! Remember, this is 2 hours DVD!
The First part is about breathing, relaxation and getting into a combat trance state. The second part has a lot of different combat techniques, starting from basic movement to takedown techniques, joint locks, grabs, working with a knife, etc.
I've watched this Spetsnaz DVD 5 times already and every time I learn something new. A lot, a lot of important self-defense elements here!
