Sure, that’s an option. I think that falls outside of PttP’s narrow focus though.
Keep in mind that it was a different world when the book was released. In the world I grew up in no one knew how to strength train without a gym full of equipment. It was all bodybuilding anyway. Weightlifting coaches were expensive and hard to find. You weren’t able to just run down to K-Mart and buy a squat stand, there wasn’t enough room in the basement anyway. There was no YouTube to teach you different exercises.
Well, that was my experience anyway. That book was a real paradigm shift for me.
