Americas NEXT Ninja Warrior

We are hitting a phase of MAJOR ENERGY!  Of course, right when we decide to take a break from sports...this boy is in need of constant challenges--physically and mentally.  Xander has watched America's Top Ninja several times and he really wants to get on that bandwagon...We would love to have him participate in every sport but unfortunately it all costs a lot of money and well, that has to be divided out so I guess our kitchen, my walls, furniture and everything else we own will be his training ground?
