We present an analysis of far--infrared (FIR) [CII] and [OI] fine structureline and continuum observations obtained with $Herschel$/PACS, and CO(1-0)observations obtained with the IRAM Plateau de Bure Interferometer, of LymanBreak Analogs (LBAs) at $z\sim 0.2$. The principal aim of this work is todetermine the typical ISM properties of $z\sim 1-2$ Main Sequence (MS)galaxies, with stellar masses between $10^{9.5}$ and $10^{11}$ $M_{\odot}$,which are currently not easily detectable in all these lines even with ALMA andNOEMA. We perform PDR modeling and apply different IR diagnostics to derive themain physical parameters of the FIR emitting gas and dust and we compare thederived ISM properties to those of galaxies on and above the MS at differentredshifts. We find that the ISM properties of LBAs are quite extreme (low gastemperature, high density and thermal pressure) with respect to those found inlocal normal spirals and more active local galaxies. LBAs have no [CII] deficitdespite having the high specific star formation rates (sSFRs) typical ofstarbursts. Although LBAs lie above the local MS, we show that their ISMproperties are more similar to those of high-redshift MS galaxies than of localgalaxies above the main sequence. This data set represents an importantreference for planning future ALMA [CII] observations of relatively low-mass MSgalaxies at the epoch of the peak of the cosmic star formation.
