The non perturbative nature of QCD at low energies poses a challenge in obtaining the properties of hadrons. LQCD has proven to be a useful tool for studying the structure of states that are stable under the strong interactions, which are a small fraction of the states present in QCD. In this talk, I will present efforts to study the structure of the majority of QCD states, which are either unstable or bound states of other hadrons. I will consider the simplest non-trivial case represented by the rho meson and illustrate an approach to extract its electromagnetic form factors. To this end I will present the status of the numerical implementation of recently proposed formalism that allows for the extraction of electromagnetic scattering amplitudes from which one may then extract the form factors of the rho.
