(g<sub>$B&L(B</sub>-2)/2, at Brookhaven National Lab (BNL) differs with the theoretical prediction at the 3.7$B&R(B level, perhaps hinting at the existence of Beyond the Standard Model physics. To address this discrepancy, the Muon g-2 Experiment at Fermilab has been
designed to determine a<sub>$B&L(B</sub> to a precision of 140 parts per billion, a four-fold improvement over the BNL measurement. In this talk, we report the results from the Run 1 physics data set (a small fraction of the total data accumulated to date), with
an uncertainty of 460 parts per billion, which is 15% smaller than the BNL uncertainty. Additionally, an overview of the experimental technique will be presented, along with a detailed discussion of key aspects of the measurement.</span><o:p>
