Star-forming galaxies are known to follow a relatively tight relation between their stellar masses and star formation rates, dubbed the 'galaxy main sequence'. As part of the MUSE Hubble Ultra Deep Field survey, we have obtained deep spectroscopy for well over a thousand galaxies across cosmic time (0<z<7). Using these unique data, we investigate the star formation rate in low mass galaxies, reaching down to very low rates (0.005 Msun/yr). In this talk, I will present the latest view on the low-mass end of the galaxy main sequence (between log M* = 7-10) and discuss its implications for feedback in low mass galaxies at z<1.
