The most hardcore gym I have ever seen was a playground in a poor run down urban black neighborhood. Guys were doing dips, chins, pushups, burpees, single leg squats and other body weight exercises. At the end they all go for a run.
The guys were ripped and in shape. The next town over in the rich white neighborhood has a gym with every possible contraption is filled with soft white guys. Only the drug users in the gym look like bodybuilders.
I will bet my last dollar that the push up and chin crowd would wipe the floor with the super gym crowd if push came to shove.
