"Ready for Labour and Defence of the USSR" (abbreviated as GTO) was the All-Union physical culture training programme, introduced in the USSR on March 11, 1931 on the initiative of the Komsomol. It was a complement to the Unified Sports Classification System of the USSR. While the latter provided Soviet physical education system requirements only for athletes, GTO was a programme for all Soviet people of almost all ages. By the year 1976, 220 million people were awarded GTO badges.
