Patent abstract
A wrist strengthening device includes a first handle, a second handle coupled to the first handle, and a tightening component coupled to the first handle and the second handle. The tightening component is configured to provide resistance to movement of the first handle and the second handle as the first handle is moved in a first direction and the second handle is moved in a second direction, opposite the first direction. The tightening component includes an outer piece, an inner piece, and a male and a female portion. Movement of the male portion toward the female portion causes space between the inner piece and the outer piece to decrease and friction therebetween to concurrently increase.
