A device that exercises a wrist of a user by converting a pivotal motion into a linear motion. The device includes a base, a pair of pivoting assemblies, a pair of resistance assemblies, and a grip. The base is placed on a support surface. The pair of pivoting assemblies extend upwardly from the base and are spaced apart from each other to have the wrist of the user placed therebetween. The pair of resistance assemblies depend from the pair of pivoting assemblies, respectively, to the base. The grip extends from one pivoting assembly to the other pivoting assembly and is gripped by a hand of the user, and when pivoted downwardly by the hand of the user, the pair of pivoting assemblies pivot downwardly which in turn causes the pair of resistance assemblies to extend linearly upwardly and provide a resistance, and in doing so, converts the pivotal motion into the linear motion.
