I know somebody who puts their weights in the freezer before they use them. (photographic proof: http://i41.tinypic.com/24473ow.jpg) I have no clue why they do this, and they refuse to explain the purpose behind the action. Is there any physics related meaning to this action? Somebody else mentioned that the energy required to warm his hands from the freezing temperature of the weights might mean more calories utilized, but I can't imagine that you would use that many calories to warm your hands. Any ideas?
