Description:

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a shrouded weight stack for a body building system with the capability of selectively varying the weight to be lifted by a user in a safe, convenient and economical manner.

2. Description of the Prior Art

The use of exercise systems of known designs and configurations is known in the prior art. More specifically, exercise systems of known designs and configurations previously devised and utilized for the purpose of varying resistance for exercise through known methods and apparatuses are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.

By way of example, U.S. Pat. No. 5,011,139 issued Apr. 30, 1991 to Towley relates to an Assisted Dip/Chin Exercise Device and U.S. Pat. No. 4,842,271 issued Jun. 27, 1989 to Vinciguerra relates to a Leg Extension Exercise Machine with Leg Length and Exercise Motion Range Adjustment Apparatus.

While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a shrouded weight stack for a body building system with the capability of selectively varying the weight to be lifted by a user in a safe, convenient and economical manner.

In this respect, the body building system with a shrouded weight stack according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of shrouding a weight stack for a body building system with the capability of selectively varying the weight to be lifted by a user in a safe, convenient and economical manner.

Therefore, it can be appreciated that there exists a continuing need for a new and improved body building system with a shrouded weight stack which can be used for selectively varying the weight to be lifted by a user in a safe, convenient and economical manner. In this regard, the present invention substantially fulfills this need.
