A term coined by exercise scientist Dr Mike Israetel in relation to poorly designed exercise equipment.
"I made up a term uh back back a few years ago when I was debating some biomechanics folks called
diagrammatical biomechanics where you looked at some diagrams and you're like 'Ehhh... this must be how the human body works!' and you made a machine only on that."
"You tried that machine over there?"
"It fucking sucks, the creators were probably on some diagrammatical biomechanics bullshit."
