Wrist arm exerciser

Abstract

A portable, compact exerciser comprising a semi-rigid torsion member with a pair of gripping surfaces at each end. The end faces of the gripping surfaces are designed to receive detachable handles orthogonally to the longitudinal axis of the torsion member. The torsion member comprising thin walled sections running along the longitudinal axis to offer resistance to any rotational force applied about the longitudinal axis of the torsion member. In one mode of operation, the user can primarily exercise the wrists by rotating the torsion member by rotating the gripping surfaces in a direction relative to each other. In another mode of operation, by moving the detachable handles attached to the gripping surfaces back and forth relative to each other in a plane orthogonal to the longitudinal axis of the torsion member, the user can exercise forearms and other muscle groups. The torsional resistance of the torsion member can be conveniently increased by using attachments that can be clipped on to the thin walled sections. Due to its simple construction, the exerciser can be easily manufactured at a low cost.
