The Combat Flow DVD is about how to use different energy techniques in self-defense, or how Vadim defines it: 25% of physical strength and 75% of inner energy. This 2 hours DVD has instructions how to use your energy in the fighting, with exercises like the figure 8 motion. It really helped me to get more flexibility and to use energy leverage on my enemies. Not only it teaches how to deal with fist fighting, but also disarming enemies from different weapons, for example, a knife. This Systema Spetsnaz DVD is a must have video, and an important part of the seminar set!
