  We study the resonant decay of the primordial Standard Model Higgs condensate
after inflation into $SU(2)$ gauge bosons on the lattice. We find that the
non-Abelian interactions between the gauge bosons quickly extend the momentum
distribution towards high values, efficiently destroying the condensate after
the onset of backreaction. For the inflationary scale $H = 10^8$ GeV, we find
that 90% of the Higgs condensate has decayed after $n \sim 10$ oscillation
cycles. This differs significantly from the Abelian case where, given the same
coupling strengths, most of the condensate would persist after the resonance.
