We use the adiabatic compression theory to build a physically well-motivated Milky Way mass model in agreement with observational data. The visible mass of the Galaxy is distributed in a spheroidal bulge and a multi-component disc parametrized by three galactic parameters, the Sun distance to the galactic centre, R₀, the total bulge mass, M_bulge, and the local disc surface density, Σ_☉. To model the dark matter component, we adiabatically compress a Navarro, Frenk and White (NFW) halo (with concentration c and total mass M_vir) for fixed values of the spin parameter λ, the fraction of the mass in baryons m_b, and the thin disc contribution to total angular momentum j_d. An iterative selection procedure is used to explore in detail the wide space of parameters only selecting those combinations of { R₀, M_bulge, Σ_☉, λ, m_b, j_d, c, M_vir } that give rise to a Milky Way model in agreement with observational constraints. This analysis leads us to conclude that only models with R₀=8.5kpc, 0.8x10¹⁰M_☉<M_bulge<1.6x10¹⁰M_☉ and 49M_☉/pc²≤Σ_☉≤56M_☉/pc² can be reconciled with the set of observational constraints. As regards the parameters entering the adiabatic compression, we find 0.03≤λ≤0.10 and 0.04≤m_b≤0.10, while final estimates of the parameters describing the initial halo profile turn out to be 5≲c≲12 and 7x10¹¹M_☉≲M_vir≲17x10¹¹M_☉ (all at 95.7% CL).
