Never personally had my own fighter ..Which i could say ..I trained him..
But i worked with a fair few good kids
Like between 11 and 14 odd year olds.. Its a pretty good age when you get the right kids
None of this little chavvy kid crap... Jus genuinely promising young nice kids..
Test em out a bit.. See what works for em and did a fair bit of gentle sparring with em..
Its very satisfying training young ones in a weird way..lol
Peace
