  We examine the charged boson and right-handed neutrino contribution to the
muon g-2 anomaly in the twin Higgs models with the joint constraints of the
Higgs global fit data, the precision electroweak data, the leptonic flavor
changing decay \mu \to e\gamma, and the mass requirement of the heavy gauge
bosons. It comes out with the conclusion that some parameters such as the
coupling of charged Higgs to the lepton y_\mu, the top Yukawa y_t, and the
heavy gauge boson coupling to the lepton V_\mu are constrained roughly in the
range of 0.12\lesssim y_\mu\lesssim 0.4, 0.4\lesssim y_t\lesssim 0.9, and
0.47\lesssim V_\mu\lesssim 1, respectively.
