We consider critical points and solutions of the gradient flow for variational integrals with integrands satisfying a Legendre-Hadamard condition. We show that if a solution of the Euler-Lagrange system or the gradient flow has first (spatial) derivatives which are bounded and of vanishing mean oscillation, higher regularity follows.
