By means of a coupled channel non-perturbative unitary approach, it is possible to extend the strong constrains of Chiral Perturbation Theory to higher energies. In particular, it is possible to reproduce the lowest lying resonances in meson-meson scattering up to 1.2 GeV using the parameters of the O (p²) and O (p⁴) Chiral Lagrangian. We report on an update of these results examining their possible relevance for meson spectroscopy
