I will discuss the Vainshtein mechanism in theories of modified gravity and present an intriguing scaling argument of the Vainshtein radius. Then in the explicit framework of bi-gravity I will discuss several phenomenological implications of this theory on galactic and cluster scales. I will present new limits in the graviton mass parameter space and discuss the implications of this framework for the local dark matter density.
