Upright gluteus isolation weightlifting machine

Abstract

Weightlifting apparatus may be used by a person in a standing position to exercise gluteus muscles. The apparatus may include a pivoting exercise assembly configured to be positioned at hip level of the person and to be pivoted by a leg of the person. A shoulder brace assembly may be configured to provide constraint against a shoulder of the person. A chest brace assembly may be configured to provide constraint against a chest of the person.

1 . Weightlifting apparatus for use by a person in a standing position to exercise gluteus muscles, comprising:
 a pivoting exercise assembly configured to be positioned at hip level of the person and to be pivoted by a leg of the person;   a shoulder brace assembly configured to provide constraint against a shoulder of the person; and   a chest brace assembly configured to provide constraint against a chest of the person.   
     
     
         2 . The apparatus of  claim 1  wherein the pivoting exercise assembly includes a pad located to be positioned under a knee of the person when the person is in a relaxed exercise-starting position. 
     
     
         3 . The apparatus of  claim 2  wherein the pad is located behind the knee of the person when the person is in an extended-force exertion position. 
     
     
         4 . The apparatus of  claim 1  further comprising:
 a cable connected between the pivoting exercise assembly and a set of weights; and 
 a force-equalizing crescent attached to the pivoting exercise assembly, 
 wherein a portion of the cable passes over the force-equalizing crescent so that force applied to the pivoting exercise assembly by the weights is equalized as the pivoting exercise assembly is pivoted. 
 
     
     
         5 . The apparatus of  claim 1  wherein the shoulder brace assembly is configured to be adjustably positioned at a top of a shoulder of the person. 
     
     
         6 . The apparatus of  claim 5  wherein the shoulder brace assembly includes a hand grip. 
     
     
         7 . The apparatus of  claim 1  wherein the pivoting exercise assembly, the shoulder brace assembly and the chest brace assembly are configured to have right and left hand sides so that either a right or left leg of the person can pivot the pivoting exercise assembly. 
     
     
         8 . A weightlifting apparatus comprising:
 weights;   a pivoting exercise assembly;   a cable interconnecting the weights and the pivoting exercise assembly; and   a force-equalizing crescent attached to the pivoting exercise assembly,   wherein a portion of the cable passes over the force-equalizing crescent so that force applied to the pivoting exercise assembly by the weights is equalized as the pivoting exercise assembly is pivoted.   
     
     
         9 . A method for exercising gluteus muscles comprising the steps of:
 bracing a shoulder of an exercising person against a shoulder brace assembly;   raising a knee of the exercising person to hip level;   placing the knee over a pad of a pivoting exercise assembly;   pushing the pad downwardly against resistance of weights attached to the pivoting exercise assembly;   continuing downward pushing until a leg of the exercising person is straight and is extended behind the person.   
     
     
         10 . The method of  claim 9  further comprising the step of bracing a chest of the exercising person against a chest brace assembly
