I describe a novel way to produce states associated to geodesic motion for classical particles in the bulk of AdS that arise from particular operator insertions at the boundary

at a fixed time. When extended to black hole setups, one can understand how to map back the geometric information of the geodesics back to 

the properties of these operators. In particular, the presence of stable circular orbits in global AdS are analyzed. The classical Innermost Stable Circular Orbit 

(ISCO) play an important role separating metastable state excitations from those that quickly  fall in the horizon of  black hole. In the dual CFT, this metastability effect must be a non-perturbative effect due to the curvature on the boundary.
