We use the Higgs coupling and the muon anomalous magnetic moment measurementsto constrain the parameter space of the natural supersymmetry (SUSY) in theGeneralized Minimal Supergravity (GmSUGRA) model. We scan the parameter spaceof the GmSUGRA model with small electroweak fine-tuning measure ($\Delta_{\rmEW} \leq 100$). The parameter space after applying various sparticle massbounds, Higgs mass bounds, B-physics bounds, the muon magnetic momentconstraint, and the Higgs coupling constraint from measurements at HL-LHC, ILC,and CEPC, is shown in the planes of various interesting model parameters andsparticle masses. Our study indicates that the Higgs coupling and muonanomalous magnetic moment measurements can constrain the parameter spaceeffectively. It is shown that $\Delta_{\rm EW}\sim$ 30, consistence with allconstraints, and having supersymmetric contributions to the muon anomalousmagnetic moment within 1$\sigma$ can be achieved. The precision of $k_b$ and$k_{\tau}$ measurements at CEPC can bound $m_A$ to be above 1.2 TeV and 1.1 TeVrespectively. The combination of the Higgs coupling measurement and muonanomalous magnetic moment measurement constrain $\tilde{e}_R$ mass to be in therange from 0.6 TeV to 2 TeV. The range of both $\tilde{e}_L$ and$\tilde{\nu}_e$ masses is 0.4 TeV $\sim$ 1.2 TeV. In all cases, the$\tilde{\chi}_1^0$ mass needs to be small (mostly $\leq$ 400 GeV). Thecomparison of bounds in the $\tan\beta - m_A$ plane shows that the Higgscoupling measurement is complementary to the direct collider searches for heavyHiggs when constraining the natural SUSY. A few mass spectra in the typicalregion of parameter space after applying all constraints are shown as well.
