We analyze the impact of data from the full Run 1 of the LHC at 7 and 8 TeV on the CMSSM with 
and 
and the NUHM1 with , incorporating the constraints imposed by other experiments such as precision electroweak measurements, flavour measurements, the cosmological density of cold dark matter and the direct search for the scattering of dark matter particles in the LUX experiment. We use the following results from the LHC experiments: ATLAS searches for events with 
accompanied by jets with the full 7 and 8 TeV data, the ATLAS and CMS measurements of the mass of the Higgs boson, the CMS searches for heavy neutral Higgs bosons and a combination of the LHCb and CMS measurements of 
and 
. Our results are based on samplings of the parameter spaces of the CMSSM for both 
and 
and of the NUHM1 for with 6.8
, 6.2 and 1.6
points, respectively, obtained using the MultiNest tool. The impact of the Higgs-mass constraint is assessed using FeynHiggs 2.10.0, which provides an improved prediction for the masses of the MSSM Higgs bosons in the region of heavy squark masses. It yields in general larger values of 
than previous versions of FeynHiggs, reducing the pressure on the CMSSM and NUHM1. We find that the global 
functions for the supersymmetric models vary slowly over most of the parameter spaces allowed by the Higgs-mass and the searches, with best-fit values that are comparable to the 
for the best Standard Model fit. We provide 95 % CL lower limits on the masses of various sparticles and assess the prospects for observing them during Run 2 of the LHC.
