Abstract
The results of pedagogical research aimed at the experimental substantiation of the developed and modernized block-modular training system for improving the motor training system of young men of senior classes with the interdependent participation of teachers of pre-conscription military education and physical culture are presented. Modular training contributed to the effective provision of flexibility to adapt to the individual needs of senior school age boys to the level of their basic motor training that meets the normative requirements for the physical fitness of pre-conscription youth. The use of the principle of modular training allows a teacher of pre-conscription military education and a teacher of physical education to make adjustments in the course of the educational process without violating its single target content.
