  We present on shell-scheme for the 2PI formalism with a particular focus on
the renormalized equations of motion. We first revisit the so-called Hartree
approximation where we give the counterterms for both the broken and unbroken
phase. Moreover, we give explicit formulas for the renormalized three- and
four-point functions in the broken phase. We then turn to the sunset
approximation, with only scalars and then including fermions. We give explicit
formulas for the wavefunction and mass counterterms. Moreover, we show that, in
particular, the two-point functions can be obtained numerically in a fast
converging scheme even for large couplings of order one.
