Children are intelligent & if they see that we ask a lot from them & not the same from ourselves, failure is guaranteed.
Does that mean that we need to be in unbelievable shape & be training the same amount of hours as the players we coach, absolutely not!
But showing the players we train that we are able to take care of our health, manage our time & in general are able to lead our own life is a very strong signal that undoubtedly will increase the amount of trust & respect the players have got for us.
