Of course they did it for wrestling. They have to drop weight and be weighed in and then it is okay for the weight to come right back after weigh in. LOL The bad part about wrestling, unfortunately. They would end up getting so dehydrated from trying to cut weight that some of the guys would actually get sick or pass out before their match. Definitely not the best way to go into a match. I always preferred wrestling in a higher weight class so I could put on weight instead of dropping. Being the smallest in that weight class makes you faster then your opponent too!
