Jiu Jitsu Ryu SDA Vol.1

The work of Jiu-Jitsu Ryu is that of preserving and interpreting the old techniques so that they can be used in our times. From the hand of Renshi Hanspeter Ruesch, chief instructor and founder of Jiu-Jitsu Ryu / Self Defense Association, you will discover the same essence as that authentic Jiu-Jitsu, safe in its practice, but lethal in its street application.
