  We prove local Lipschitz regularity for local minimiser of \[
W^{1,1}(\Omega)\ni v\mapsto \int_\Omega F(Dv)\, dx \] where $\Omega\subseteq
{\mathbb R}^N$, $N\ge 2$ and $F:{\mathbb R}^N\to {\mathbb R}$ is a
quasiuniformly convex integrand in the sense of Kovalev and Maldonado, i.e. a
convex $C^1$-function such that the ratio between the maximum and minimum
eigenvalues of $D^2F$ is essentially bounded. This class of integrands inculdes
the standard singular/degenerate functions $F(z)=|z|^p$ for any $p>1$ and
arises naturally as the closure, with respect to a natural convergence, of the
strongly elliptic integrands of the Calculus of Variations.
