With the imminent launch of COROT and the preparation of new helioseismology instruments such as GOLF-NG (cf. DynaMICS project), we need a coherent picture of the evolution of rotating stars from their birth to their death. We describe here the modeling of the macroscopic transport of angular momentum and matter in stellar interiors that we have undertaken to achieve this goal. First, we recall the dynamical processes that are driving this transport in rotating stars and the theoretical advances we have accomplished. Then, we present our new results of numerical simulations which allow us to follow in 2D the secular hydrodynamics of rotating stars, assuming that anisotropic turbulence enforces a shellular rotation law. Finally, we show how this work is leading to a dynamical vision of the Hertzsprung-Russel diagram in support of asteroseismology and helioseismology.
