1. A progressive hand grip strengthening system for strengthening the hand grip of a user in an isometric mode while other muscles of the user are being strengthened in an isotonic mode by a separate exercise equipment to which the hand grip strengthening system is connected, the hand grip strengthening system comprising:
a plurality of differently sized and weighted hand-graspable devices each connectable to a separate pre-selected exercise equipment and each hand-graspable device comprising:
a first portion having a hand-graspable surface having a pre-selected circumference;a second portion having a hand-graspable surface having a pre-selected circumference that is smaller than the pre-selected circumference of the first portion;and a connection member,wherein the first and second portions each comprise
a rigid body member having a central axis, wherein the axis of the first and second portions is co-linear to define a central axis of the hand-graspable device,spaced apart first and second ends,a hand-graspable outer surface having a pre-selected circumference and shape between the first and second ends of the rigid body member for receiving fingers of a user's hand in any degree of openness in planes parallel to the central axis,and a collar member coupled to a second end of the body member,and wherein the connection member extends from the first end of the rigid body member of the first portion to connect the exercise device to the separate exercise equipment, and the connection member is pivotally coupled to the first end of the rigid body member of the first portion to allow rotational movement of the hand-graspable device about its central axis with relative to its connection member. |
