Olympic lifting is such an enigma to most people, it's kind of funny to hear comments or catch people staring like you have a dick growing out of your forehead. The other week I had 120kg on the bar, resting on the floor. As I walk up to it and get ready to grab it, some guy next to me says "You should use a belt when you deadlift." So then I clean and jerked the 120kg, turned to him and said "Nah, I don't need a belt." I guess 120kg is more than many people can C&J, but it is far from what I would consider impressive.
