In this paper, I show that backward (in time) running states can be explicitly accounted for by expanding the interpolator basis in the variational method in lattice QCD. The backward running states can then be removed by choosing an appropriate linear combination of interpolators, which improves the signal significantly. The proof of principle, which also makes use of the time-shift trick (generalized pencil-of-functions method), will be delivered at an example on a 644 lattice close to the physical pion mass.
