Soviet body builders only used free weights and a pull-up bar. You don’t need anything but that to get big muscles. Similarly, you don’t need anything except a chalk board to teach math and most other subjects.
You may also need steroids, which Soviet body builders definitely used.

Though before that I could definitely see any sort of doping would be very un-Soviet.
Now I sometimes shake my head when I see comments like "I do not know programming, which language (or worse—fraamework) should I learn?" It is so tempting to say "duh, learn programming and worry about the languages later".
A true bench press with a bar is much better than a machine imitation of the same muscle groups.
