Abdominal Exerciser Utilizing Musculature of Lower Body

Abstract

The present invention is comprised of a frame having two upright side members. The upright side members are linked at their bottom end by a cross member. There may also be an upper member across the top end of the upright side members. A user of the device should preferably assume a sitting posture when initiating an exercise routine involving the device. At the start of the exercise, the user takes hold of both upright members and places one or both feet on the cross member. The user then elevates the foot or feet that is resting on the cross member off the floor by tensing muscles of the abdomen and lower back.

What is claimed: 
     
         1 . An abdominal exercise device comprising; an upright member having a top end and a bottom end, said one upright member being in a substantially parallel orientation as a second upright member, said second upright member having a top end and a bottom end; and a crossmember connecting said one upright member to said second upright member, said crossmember being substantially perpendicular to said upright member and said second upright member. 
     
     
         2 . The abdominal exercise device of  claim 1 , wherein said upright member and said second upright member further comprising a grip surface. 
     
     
         3 . The abdominal exercise device of  claim 1 , wherein said upright member and said another upright member are further comprised of telescoping parts, wherein said telescoping parts of each said upright member capable of collapsing or expanding a length of said upright member and said second upright member. 
     
     
         4 . The abdominal exercise device of  claim 1 , wherein said crossbeam capable of substantially immobilizing user's feet. 
     
     
         5 . The abdominal exercise device of  claim 4 , wherein said user's feet are immobilized using a frictional surface. 
     
     
         6 . The abdominal exercise device of  claim 4 , wherein said user's feet are immobilized using a bracket attached to said crossbeam. 
     
     
         7 . The abdominal exercise device of  claim 1 , wherein said upright member and said another upright member further comprising a bend, said bend originating from said bottom end and terminating along the length of said upright member, wherein said bends of said upright members being in of a substantially parallel orientation with one another. 
     
     
         8 . The abdominal exercise device of  claim 7 , wherein the angle of said bend with respect to the other sections of each upright member, may be altered. 
     
     
         9 . An abdominal exercise device comprising; an upright member having a top end and a bottom end, said one upright member being in similar orientation as another upright member, said another upright member having a top end and a bottom end; a crossmember connecting said one upright member to said another upright member, said crossmember being substantially perpendicular to said upright member and said another upright member; and wherein said upright member and said another upright member further comprising a bend, said bend originating from said bottom end and terminating along the length of said upright member, wherein said bends of said upright members being in similar orientation with one another. 
     
     
         10 . The abdominal exercise device of  claim 9 , wherein said upright member and said another upright member having a grip surface. 
     
     
         11 . The abdominal exercise device of  claim 9 , wherein said upright member and said another upright member have telescoping parts, wherein said telescoping parts of each said upright member capable of collapsing or expanding said each upright member. 
     
     
         12 . The abdominal exercise device of  claim 11 , wherein an angle of said bend is adjustable. 
     
     
         13 . The abdominal exercise device of  claim 9 , wherein said crossbeam capable of substantially immobilizing user's feet. 
     
     
         14 . The abdominal exercise device of  claim 9 , wherein a point of intersection of said one upright member with said crossmember and a point of intersection of said another upright member with said crossmember each in form of a hinge, each said hinge determining the pitch of said upright members. 
     
     
         15 . An abdominal exercise device comprising; an upright member having a top end and a bottom end, said one upright member connecting to two diagonal members, each one of said diagonal member connecting on their opposite ends to another upright member wherein said upright member connected to opposite ends of said diagonal members being in similar orientation with one another and at bottom end of each said upright members connecting to a crossmember, wherein said crossmember being perpendicular to each said another upright member, and wherein said crossmember linking each said upright member. 
     
     
         16 . The abdominal exercise device of  claim 15 , wherein said upright member further comprises telescoping parts, wherein said telescoping parts capable of collapsing or expanding said member. 
     
     
         17 . The abdominal exercise device of  claim 15 , wherein each said upright member further comprises a bend, wherein the angle of said bend is adjustable. 
     
     
         18 . The abdominal exercise device of  claim 15 , wherein said crossbeam capable of substantially immobilizing user's feet.
