Models in extra dimensions have unique features. Many of their surprising properties simply result from the underlying 5D structure. This structure shows up as ``sum rules'' involving the whole tower of Kaluza-Klein factors. In this paper, we present a holographic shortcut and derive these results without solving the eigenvalue problem: we express 4D physical quantities directly in terms of the 5D metric. In warped space, one can go further and isolate the effect of the new physics sector. This method can be used for any 5D model, and we apply it here to the case of holographic QCD and holographic technicolor.
