My current son has wrestled for 6 years and has never had to cut one single pound, starting the year you figure out where they are after a few weeks of practice. If they are over half way to the next I always wrestled him up knowing he would be there by years end.
If you go down in weight to dodge someone, well you will find that someone down there also. May just have a different name....lol
When sub start it get hard for a lot, 1-3 week in a row on the road at times in hotels at time is not a real good combo, but some of it is we are talking about growing kids.
To not hit a growth spurt or add weight from October to end of March is going to happen.
Adjust from the start and let them be good eating growing kids.
