Serves you right
This is what happens when you use a Smith machine in a gym:
Never use a Smith machine, for yea verily, to do so is to violate one of the Ten Commandments of the Iron God. And that, truly, doth be a mortal sin against the Lord of Gains.
Do not use a Smith machine. Do not look at a Smith machine. Do not fail to roundly mock the idiots who insist that a Smith machine is in any way useful or good. Do not bother so much as touching a Smith machine.
Instead, why not do something productive with your time - like going over to the squat rack and doing squats and deadlifts? Or, perhaps, helping to clear the way so that a certain Didact can become Supreme Ruler of Mankind, and therefore make his first act the abolition, now and forever, of Smith machines from the gym? Followed immediately by the institution of a 112mph speed limit on all highways, and then a break for lunch and a nap?
Truly, I am kind.
