It has recently been shown that relaxed spherically symmetric dark matter halos develop from the inside out, by permanently adapting their inner structure to the boundary conditions imposed by the current accretion rate. Such a growth allows one to infer the typical density profiles of halos. Here we follow the same approach to infer the typical spherically averaged profiles of the main structural and kinematic properties of triaxial, anisotropic, rotating halos. Specifically, we derive their density, spatial velocity dispersion, phase-space density, anisotropy and specific angular momentum profiles. The results obtained are in agreement with available data on these profiles from \nbody simulations.
