I wear a belt and thats it. I squat a bit of a hybrid between powerliftin and O lift. The bar is lower like a powerlift but legs are more of a O lift style, maybe a little bit wider. I have experimented for a long time and found where the bar is comfortable, but safe, and where my legs are strong and safely placed.
I said the wrong word at the start. I am not getting more into powerlifting, I am getting more into Olympic Lifting
