Saw a guy today squatting using the smith machine. Now normally when you squat, the bar is over the mid-foot, because if it wasn't you'd just fall over. Except this guy, by virtue of the fact he was on a smith machine actually had the bar about half a foot further back than he should so he was literally leaning backwards on the bar as he went down. He achieved this by literally having a completely vertical torso.
He proceeded to load some more weight on, and do a bunch of really life-threatening looking bouncy half-squats while leaning significantly backwards. Fuck.
