I took a class in graduate school with Professor Galen Cranz called Body Conscious Design. That is where this idea started. The class was all about how to design better spaces, furniture and other things for the health of our bodies. Much of our built environment, down to the typical chair that often causes back problems, are not great for human health. This architectural detail helps prevent the atrophy of the upper body muscles. One of my projects in school had monkey bars in every hallway for an alternate means of travel.
