Abstract
Abstract A miniature lumbar block is secured along an inside of the belt normally worn by power lifters so as to enhance the maintaining of the normal lordotic curve in the lower spine while lifting. The lumbar block incorporates an extension which contacts against the spinous process of a wearer in use, but is of a width to just fall short of contacting the paravertebral muscles when centered against the spinous process.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
139 words
Apparatus comprising: a weight lifting belt releasably placed around the waist of a user, said belt including (a) a support block in the configuration of a half cylinder having a curvilinear arc surface extending outwardly from a flat inner surface of said belt; (b) with said support block having an extension layered onto the curvilinear arc of the cylindrical surface of said half-cylinder; (c) with said extension being oriented substantially orthogonal to the length of said belt; and (d) with said extension being of a width of the order of 2.5 cm; such that when said weight lifting belt is worn with said extension centered about the spinous process of a user, said extension falls short of contacting the paravertebral muscles of said user; whereby the lordotic curve of the user can be maintained while performing weight lifting maneuvers.
Claim 2
Dependent Claim
139 words
Apparatus comprising: a weight lifting belt releasably placed around the waist of a user, said belt including (a) a support block in the configuration of a half cylinder having a curvilinear arc surface extending outwardly from a flat inner surface of said belt; (b) with said support block having an extension layered onto the curvilinear arc of the cylindrical surface of said half-cylinder; (c) with said extension being oriented substantially orthogonal to the length of said belt; and (d) with said extension being of a width of the order of 2.5 cm; such that when said weight lifting belt is worn with said extension centered about the spinous process of a user, said extension falls short of contacting the paravertebral muscles of said user; whereby the lordotic curve of the user can be maintained while performing weight lifting maneuvers.
