There are many ways to keep kids of all ages physically fit besides sports.
If your child is a natural athlete or sports lover,he or she is probably already active and relatively easy to get moving.But if,like me,you are
the parent of a junior sofa potato,complete with
a video-game controller in one hand and a bag of
potato chips in the other,you know what it is
like to have your advice to go outside to play
met with,at best,silence or at worst,cry and
protest.

这段中
you know what it islike to have your advice to go outside to play met with,at best,silence or at worst,cry and protest.这句话怎么理解，什么意思？

我是这样理解的：你知道如果你建议他出去玩耍会带来什么吗？最好的结果可能孩子只是沉默，而最坏的结果是哭闹和抗议。
