You don't need resources such as exclusive workout facilities, dieticians, or multiple athletic trainers to properly cut weight. They certainly help and it makes things much more accesible and easier to do though. If you do it correctly it should be considered watching your weight. I was a multiple time state placer and wrestled at Indiana University. When transitioning I did not change many of my habits other than working out right before weighing in. Most elite high schools implement this, and unfortunately I was not a part of an elite high school program.
At the end of the day your diet and the frequency in which you work out go hand-in-hand when you are properly cutting weight. People think that working out more will fatigue you, but if you are doing it properly, it does not fatigue you. I also found that when crash-cutting I would cramp a lot easier, my muscles were tight from dehydration, and in general I was just sore from malnutrition. I also felt better when I was working out multiple times a day and still eating the day of weigh ins. For example, after practice I would go to another practice, or simply just go to a gym and run/sauna. I did this on Sunday's, Monday's, Wednesday's, and Thursday's.
Also based on my experiences with cutting weight in high school, I suggest anyone cutting more than 10 pounds moves up a weight. When you begin focusing on how much weight you need to lose in a practice rather than what you need to do to get better, it effects your growth and development. You also see kids burn out faster as well.
