Gladiators was incredible TV for me as an 8 year old.
I never got into WWE as a country kid but watching Gladiators and hearing "and the last Gladiator in the Gauntlet is........ VULCAN!!!! Used to just send me around the room like a headless chook. Same for Taipan on rings.
Also playing mock Gladiator games like Pyramid on couches was amazing.
They have the balance beam above a foam pit with the foam paddle things at the trampoline joints around the place. Pretty good. I knocked my 3 year old off a few times just to remind him who's boss
