We present a first-principles lattice QCD thorn QED calculation at physical pion mass of the leading-order hadronic vacuum polarization contribution to the muon anomalous magnetic moment. The total contribution of up, down, strange, and charm quarks including QED and strong isospin breaking effects is a(mu)(HVP LO) = 715.4(18.7) x 10(-10). By supplementing lattice data for very short and long distances with R-ratio data, we significantly improve the precision to a(mu)(HVP LO) = 692.5(2.7) x 10(-10). This is the currently most precise determination of a(mu)(HVP LO).
