You want to be in the lowest weight class possible — mainly because men are generally stronger as they get bigger and you do not want to be competing against giants.
"Weight classes are divisions of competition used to match competitors against others of their own size. Weight classes are used in a variety of sports, especially combat sports (such as boxing, kickboxing, mixed martial arts and wrestling). Alternatives to formal weight classes include catch weight and openweight." ~ Wiki
The weight categories are different for each competition so find out what the weight classes are for the tournament you are competing in adecide what weight class you are going to go into and target and always choose the weight class that is below your actual weight.
For example, if you weigh 195, then you would look at the weight classes available for the tournament you are entering and choose and target the best class. As such — depending on how much time you have until the competition — if the tournament is 30+ days away and offers a 176-187lbs class, you would target this weight class because losing 8 lbs is achievable in one month's time (2 lbs/week). You would, however, not target the 165-175 class because you would have to lose 20 lbs and that would be unhealthy. To make this weight class, you would have to cut your weight to 187.0 lbs. Please note that If your scale is a older scale, you can only do the best you can to hit that target number, however, if your scale is a digital scale, it should be pretty accurate with the scales that they use at the competitions.
You should try to always be at the top of the weight category. Some smaller tournaments have less weight classes due to the reduced number of competitors and the smaller amount of people interesting the tournament. Take a look at the weight classes available and what is achievable for you at any competition that you are looking to participate in.
Factors to determine the weight class best for you are: • The amount of weight to lose; and
• The time you have to do this.
I have found that the quicker/faster & more weight you cut, the weaker and less-powerful you become, so here is always a fine line between how much weight you can lose vs. the time available and the weight category best for you in a specific competition.
