US Patent 10029140 Wrist and forearm exercise device

A portable exercise device which applies a torsional force onto the user's hands in order to engage the forearm. The exercise device includes a first grip assembly, a second grip assembly, a planar framing body, and an adjustable resistance mechanism. The first grip assembly and the second grip assembly allow the user to engage the exercise device and are positioned offset to each other across the planar framing body. The first grip assembly and the second grip assembly each include a circular hole, an elongated handle, and a rotating ring. The circular hole traverses through the planar framing body. The rotating ring is perimetrically and slidably engaged to the planar framing body within the circular hole. The elongated handle is diametrically mounted across the rotating ring. The adjustable resistance mechanism produces the resistance force and is mechanically integrated in between the rotating ring and the planar framing body.
