My thought process is my boy has been wrestling at 8U/58 all year but has been weighing in at 55.5 to 56 all year without watching what he ate now that we have been eating alot healtier he is making 55 easy why not have him go to 55 i have always put my kid up the next weight class the last 4 years just in case he hits that growth spurt but he hasnt why let him wrestle kids that out weigh him by 3 and even 5 lbs by the time they wrestle thats a big weight difference thats my thought process. Theres tough kids in every weight 55,58 and 61 i really dont think to much of a difference in were you end up but extra weight when you are wrestling someone is tough espeacially when you get to districts and state.
