We have procured astrometric epochs for 15 low-mass visual M-dwarf binaries for which we are able to place orbital constraints. From the Keplerian motions of the binaries we are able to extract dynamical masses, which will be compared to current state-of-the-art theoretical evolutionary models. The dynamical masses will eventually be used for constructing empirical models, and to improve isochronal dating of young moving groups and associations. Here we present the current status and the preliminary results from the survey.
