| I think the point is, people tend to fight at lower weight than their natural weight. So, if you are walking around at 205lbs and can easily the make the weight for the light heavyweight division, you'd be fighting guys that normally weight more than 205lbs, who just make the weight at 205lbs the day before the fight, and you'll be smaller than most light heavyweight division fighters. So, they try to fight at 185lbs and try to cut weight just for the day of the weigh in. This is not unique for MMA, it applies to any competition where there is a weight class.
Now, as you said, if the weigh-in is at right before the fight, this wouldn't be possible. The fighters will be dehydrated and not in the best shape for the fight, if they cut their weight too drastically for the fight. |
