Benefits of technology

[0003] There is, therefore, provided according to the present invention, a hand-held exercise weight that has a mass moment of inertia that substantially reduces the cyclic forces acting on the forearm during an exercise routine to reduce muscle fatigue.

Problems solved by technology

The cyclic rotation of the barbell produces an internal offsetting torque that is dependant upon the mass moment of inertia of the barbell; this cyclic internal torque eventually fatigues the forearm muscles and consequently the effectiveness of the exercise routine in developing or toning the biceps muscles.

Embodiment Construction

[0013]FIG. 1 is a perspective view of the preferred embodiment of this invention, namely, an improved exercise weight that reduces the cyclic forces acting on the forearm of the user and consequently muscle fatigue. As can be seen in FIG. 1, a cylindrical disk 1 is illustrated where the hollow portion of the disk is a void 2 extending axially along vertical axis 5 where the vertical axis is co-axial with the x-axis. As can further be seen in FIG. 1, vertical axis 5 (x-axis) is perpendicular to the plane containing lateral axis 8 (z-axis and horizontal axis 7 (y-axis) and intersects axes z and y approximately at the centroid 3, or center of gravity, of cylindrical disk 1. A grip bar 4 has a central axis 6 which is co-axial with the z-axis. In the preferred embodiment, grip bar 4 is cylindrically shaped and has a centroid that is approximately coincident with centroid 3 of cylindrical disk 1. Thus, the entire weight of the composite of the cylindrical disk 1 and grip 4 is centered at ...

Abstract

An improved hand-held barbell type exercise weight that reduces muscle fatigue consists of a circular disk that has a vertical axis perpendicular to the base of the disk, a horizontal axis perpendicular to the vertical axis and a lateral axis perpendicular to both the vertical and horizontal axes and intersecting the axes at the approximate centroid of the circular disk. The disk has an axially extending cylindrical void extending axially along the vertical axis and through the disk forming a hollow circular disk where the void is symmetrical to the plane of the vertical axis. A cylindrically shaped grip bar having a central axis that is co-axial with the lateral axis extends laterally across the void and through the centroid of the disk.

Description

FIELD OF INVENTION [0001] This invention relates to an improved hand-held barbell type exercise weight that minimizes torsion induced muscle fatigue. BACKGROUND OF THE INVENTION [0002] Barbell type hand-held exercise weights are well known in the prior art. The hand-held barbell has a grip extending between two opposing bodies of the same weight which are generally disk shaped. The centroid, or center of gravity, is a point where the entire mass of the weights and grip can be centered. The centroid in a barbell is usually located at the mid-point of the grip that extends between the weights. When exercising with a barbell, the exerciser will repeat movement of the weights in a cyclic manner using a barbell of identical weight held by each arm. The movement is intended to exercise the biceps, triceps, deltoids, and other muscles of the arms and shoulders. Forearm muscles include the brachioradialis, the mensor carpi radialis, the pronator teres, the flexor carpiradialis, and the palm...
