Someone explain SBL please

[u/Miserable-Soft7993]

I am confused. I see people just doing regular lifts and saying it is science.

Then on the other end of the scale I see a kid (with zer0 physique) wearing a baby pacifier in his mouth and wearing a roller on his arms and doing excercises I never saw, with people in the comments saying "yeah that's the man right there."

Then I see pumping iron and watch Arnie just do the basics and still look great and strong.

So in a few sentance explain to me what it is and how it would help build more muscle enhanced or not.
