I was looking on such information about Aden training philosophy and got my hands on this website that give an insight of early days of Jama coaching career.
" Aden’s started coaching with John Cook at George Mason and has strong ties to the US ie he trained some with Joe Falcon ".
So now we all know where did he get his experience and Training knowledge of middle distance!!
Could anyone tell me More about it..
