  We perform the fit of electroweak precision observables within the Standard
Model with a 126 GeV Higgs boson, compare the results with the theoretical
predictions and discuss the impact of recent experimental and theoretical
improvements. We introduce New Physics contributions in a model-independent way
and fit for the S, T and U parameters, for the $\epsilon_{1,2,3,b}$ ones, for
modified $Zb\bar{b}$ couplings and for a modified Higgs coupling to vector
bosons. We point out that composite Higgs models are very strongly constrained.
Finally, we compute the bounds on dimension-six operators relevant for the
electroweak fit.
