Back strenghthening maching

Abstract

An improved back strengthening machine 5 having a rolling cushion assembly unit 1 contoured to firmly contact all back surfaces and strengthen all dorsal muscle groups. In addition, the back strengthening machine 5 comprises: a rolling cushion assembly unit 1, weight resistance assembly unit 2, base assembly unit 3 and a handlebar assembly unit 4. While using this machine, a user will stand onto base of base assembly unit 3, hold onto hand grips adhered to handlebar assembly unit 4, and then press onto the rolling cushion adhered to rolling cushion assembly unit 1, while aligning the elevated convex cushion shape onto the spinal location. Next, the user will use knee flexion to maintain the spinning cushion adhered to rolling cushion assembly unit 1, to spin freely up and down the user's back structures.

I claim: 
     
         1 . A back strengthening machine having a rolling cushion with a convex shaped middle section attached to a weight resistance unit. 
     
     
         2 . The back strengthening machine of  claim 1  having a said rolling cushion with an innovative contour that also strengthens intervertebral muscles, thereby increasing the overall stability of all back structures. 
     
     
         3 . The back strengthening machine of  claim 1  is operated by a user during which said user will perform repetitious knee flexion to maintain spinning cushion adhered to the rolling cushion assembly unit to spin freely up and the user's back and spinal structures. 
     
     
         4 . The back strengthening machine of  claim 2  wherein during said operation said user activates the said rolling cushion with said rolling cushion assembly unit to activate weight resistance unit to freely roll up and down the back. 
     
     
         5 . The back strengthening machine of  claim 3  wherein during said operation the said user will activate the said back strengthening machine to apply an even amount of weight resistance to all back surfaces. 
     
     
         6 . The back strengthening machine of  claim 4  wherein during said operation the said user remains in a prone position on the bed cushion. 
     
     
         7 . The back strengthening machine of  claim 4  wherein during said operation the said weight resistance applied to said all back surfaces will strengthen all dorsal muscle groups and activate the piezoelectric effect to all back structures.
