We report the results obtained from VLT-isaac near-IR spectroscopy of two low-luminosity z ≃ 1.9 galaxies located in the core of the lensing cluster AC 114. The amplification factor allowed to obtain, for the first time, physical properties (SFR, abundance ratios, mass, etc.) of star-forming galaxies, 1 - 2 mag fainter than in previous studies of LBGs at z ≈ 3.
