The Fundamental Plane (FP), a tight scaling relation between galaxy size, velocity dispersion, and luminosity, offers unique insight into the structural evolution of galaxies. However, studies of the FP thus far have been limited by the difficulty in obtaining stellar kinematics measurements at z>0. The LEGA -C survey has recently delivered the largest census of galaxy stellar kinematics at z0.8, comprising a sample of 3000 massive galaxies, and enabled the first comprehensive study of the FP at z>0. I will discuss the effects of structural and stellar population properties on the FP, and show that the relation is surprisingly stable across 0
