Engaging in body building with no instructor

In the olden days, my father said that body builders have no formal training. They just buy a barbell and use it to build their muscles. I wonder how those guys could cope with the rigors of training. Now we know that body building is not just lifting weights but also having the right diet for nutrition.

I think you can still achieve it but with proper work out. Many people now doing work out without instructor. But still more achieve with instructor.
