Gravity modified theories with generic nonderivative potential V, built from the metric, are analyzed under the minimal requirement of unbroken spatial rotations. Using the canonical analysis, we classify the potentials V according to the number of degrees of freedom (DoF) that propagate at the nonperturbative level. We also compare the nonperturbative results with the perturbative DoF propagating around Minkowski and FRW background.
