RELATED APPLICATIONS

This application is a non-provisional application of prior pending U.S. Provisional Patent Application Ser. No. 62/002,440, filed May 23, 2014, which is herein incorporated by reference in its entirety.

BACKGROUND

1. Field

Embodiments of the present invention relate generally to exercise equipment. More particularly, embodiments of the present invention relate to a rack-mounted Glute-Ham Developer (GHD) and method for making the same.

2. Description of the Related Art

Glute-Ham Developers (GHDs) are known in the art. A known manufactured (or “off the shelf”) GHD may be a stand-alone exercise device including a frame joining a foot plate and associated rollers to a pad. In one exercise known as a glute-ham raise, an athlete may lay face down with their upper legs against the pad and their feet secured in-between the rollers. The athlete's upper body may be brought from a resting or downwardly-angled position upwards to a horizontal position (or “super man” position) and ultimately to an upwardly vertical position. In this way, the manufactured GHD may exercise a variety of muscle groups, including the spinal erectors (or erector spinae), the gluteal muscles, and the hamstring muscles.

Although useful, manufactured GHDs do have drawbacks. For example, manufactured GHDs tend to be relatively expensive stand-alone devices. Further, manufactured GHDs tend to take up a significant amount of floor and storage space, and may be difficult to move. Accordingly, some athletes will use other gym equipment to make “homemade” GHDs. For example, an athlete may substitute a weighted barbell for the foot plate and rollers, and may substitute a box with weights stacked thereon for the frame-connected pad. Other equipment substituted may include floor mats, exercise balls, homemade rollers, and the like. While being more affordable and somewhat easier to store and move, these homemade GHDs also have drawbacks. For example, homemade GHDs may be unstable. Further, because various elements are substituted in these homemade devices, an athlete may only receive a subpar experience relative to a manufactured GHD.

In light of the foregoing and other shortcomings in the art, it is desirable to provide an improved GHD.

BRIEF SUMMARY

It is an aspect of the invention to provide a more affordable, yet stable and effective GHD.

It is a further aspect of the invention to provide a GHD that is more easily stored and moved, yet still being stable and effective.

According to an aspect of the invention, a rack-mounted glute-ham developer may be provided. The rack-mounted glute-ham developer may include a roller assembly and a pad assembly. The roller assembly may be configured to mount to an exercise rack system. The pad assembly may be configured to mount to a support. The roller assembly and the pad assembly may be separate members (not joined by a permanent frame).

The roller assembly may be configured to mount to the exercise rack system using holes of a frame member of the exercise rack system.

The pad assembly may be configured to mount to a games box or a plyo box.

The roller assembly may include a foot plate, mounting member, support holders, roller shafts, and rollers. The mounting member may be connected to the foot plate and may also be connected to the support holders. The roller shafts may pass through rollers and holes of the support holders.

The pad assembly may include a base and one or more pads.

The rack-mounted glute-ham developer may further include a stabilizing member having a first end and a second end. The first end may be configured to mount to the exercise rack system. The second end may be configured to abut the games or the plyo box.

According to another aspect of the invention, a method of making a rack-mounted glute-ham developer may be provided. The method may include providing a flat metal blank to be formed into a foot plate, forming holes of to be created protruding members from the foot plate, and forming holes of the foot plate, bending out the protruding members, connecting a mounting member to the foot plate, connecting shaft holders to the mounting member, connecting rollers via roller shafts through holes formed in the shaft holders, and forming a base and a pad.
