This system was developed in the early USSR by teams of fighters and scientists, based on traditional Stone Age methods (5000+ years old) and was used by secret KGB groups of Elite Forces, cosmonauts and others. It is vastly unknown even in Russia.
There are a couple of examples.
In this video you can see these 2 exercises for your convenience.
