Hell even bench and presses are limited by the machine.
Some machine have their place in the bodybuilding world, but for strength it's dumbbells and bars.

"The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents... some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the light into the peace and safety of a new Dark Age."
-H.P. Lovecraft
