Like most other superhero programs, Ultimate Muscle relies on sometimes-questionable language and violence to create excitement. The characters don't swear, but they do call each other "idiot" on a pretty regular basis -- not exactly the best example. Also, while problems are usually resolved in the wrestling ring rather than with weapons, the matches can sometimes be pretty brutal (with robots occasionally getting torn to shreds).

That said, the show does help kids learn that you can do anything you set your mind to. Kid Muscle starts out as a lazy character, but it turns out that his lethargy is the result of low self-esteem. Once he starts believing in himself (and comes out from behind his famous dad's shadow a bit), he's always able to ward off his enemies.
