The Generalized Polarizabilities (GPs) are fundamental properties of the nucleon. They characterize the nucleon's response to an applied electromagnetic field, giving access to the polarization densities inside the nucleon. As such they represent a central path towards a complete understanding of the nucleon dynamics. Previous measurements have challenged the theoretical predictions, raising questions in regard to the underlying mechanism responsible for a local enhancement of the electric GP at intermediate four-momentum transfer squared. The measurement of the magnetic GP, on the other hand, promises to quantify the interplay of the paramagnetic and the diamagnetic contributions inside the proton. An overview and recent efforts on the front of the proton GPs are discussed.
