The weak cool-core cluster A3571 was observed in four XRISM Cycle 1 pointings, enabling the study of gas kinematics in a relaxed, AGN-feedback-free system. We present measurements of the velocity dispersion and bulk velocity in the core regions of A3571, out to $120$ kpc. The velocity dispersion is relatively uniform across all regions ($\\sim100-120 ~\\mathrm{km~s^{-1}}$), except in the northern gas sloshing elongation, where a $68\\%$ upper limit of $68~\\mathrm{km~s^{-1}}$ is obtained.
