So we all know that the smith machine has two good uses; firstly it makes a great pullup bar, secondly it keeps people who don't know what they're doing from taking up the squat rack. I've found a third use for the one at my gym, my epiphany came when I realised that it had free rotating collars. Suddenly it occurred to me that what we had was a free-spinning 2" thick bar that could be set up to shoulder height. All you need is a length of rope and a knowledge of knots and you've got a perfectly good wrist roller. Built one earlier today, I haven't used a wrist roller heavily since my surgery so I only went up to 20kgs (44lbs), but the thing was smooth as a motherfucker and I ended up having to take a 5 minute break before I took it apart because my hands had completly seized up. Go forth fellow S'n'Pers, repurpose the shirley machines, develop forearms that make you look like a blood relation of popeye, today we take back the shirley machines, tomorrow the world!
