My new gym has chains hanging from the barbell, and I used them two days ago for squating.

Now I realise that chains are bad ass, and they make a metalic clinking sound as they pile up on the ground, and all the girls take notice and desire that you would sire their children ------ but apart from how cool chains are, should I really use them? Is it definitely beneficial to use chains when benching, squating and deadlifting? I definitely noticed my legs were sorer than normal the next day.
