  According to the Ideal Walking Technicolor paradigm large mass anomalous
dimensions arise in gauged Nambu--Jona-Lasinio (NJL) models when the
four-fermion coupling is sufficiently strong to induce spontaneous symmetry
breaking in an otherwise conformal gauge theory. We therefore study the $SU(2)$
gauged NJL model with two adjoint fermions using lattice simulations. The model
is in an infrared conformal phase at small NJL coupling while it displays a
chirally broken phase at large NJL couplings. In the infrared conformal phase
we find that the mass anomalous dimension varies with the NJL coupling reaching
$\gamma_m \sim 1$ close to the chiral symmetry breaking transition, de facto
making the present model the first explicit realization of the Ideal Walking
scenario.
