Hi all, my son is now a yellowbelt in zen bu kan karate and is about to compete in his first comp as part of his grading for his orange belt which he should achieve by the end of the year. He is entering the kata display and also wants to go in the goundfighting. he's a big boy who is very strong fo his age but i have a few reservations as the different divisions are sorted by weight, not by age or belt.The matches are 1 minute only.Am i insane to let him try . No strikes or elbows/kicks allowed.
