I got what you were trying to say, but at the same time, you were wrong. Yes, they aren't your typical 10, 25, 35, and 45 pound weight that you would normally see at 24 Hour Fitness or Ballys, but they do not use them to fake people out into thinking they are lifting more than they are.

Crossfit exercises focus a LOT on dead lifts, clean and jerks and other exercises that have movements that have set starting and ending positions. They need to have the weights a standard size so that they don't injure themselves.
