Abdominal exercise device

Abstract

An abdominal exercise device includes a frame comprising top, middle, and bottom frame sections. The middle frame section has a curved shape for creating a teeter-totter movement during exercise. The device includes a headrest connected to the bottom frame section, a plurality of connectors for connecting elastic bands to the frame, and an elastic band connected to at least two connectors. The two ends of the elastic band are connected to two straps. The device creates the teeter-totter movement to exercise the abdominal muscles in response to a person lying down in supine position with the back of the head on the headrest and the feet in the two straps, the person applying a downward pressure with the feet to the straps to move the headrest from a resting position, and the person removing the downward pressure to allow the headrest to go back to the resting position.

         4 . The abdominal exercise device of  claim 1  further comprising one or more railings across the frame, each railing for adjusting a location of one or more connectors in the plurality of connectors, each railing comprising:
 a plurality of slots; 
 a bracket for sliding across the corresponding railing, wherein a connector in the plurality of connectors is connected to each railing's bracket; and 
 a locking element comprising one of a pin and a push in button configured to lock the bracket in a slot in the plurality of slots. 
 
     
     
         5 . The abdominal exercise device of  claim 1  further comprising:
 two armrests, each armrest comprising a top surface for placing one of an arm, an elbow, and a hand, 
 wherein the top surface of each armrest comprises a curvature configured to create a teeter-totter movement on the exercise device when the person applies downward pressure to the armrest and releases the downward pressure on the armrest. 
 
     
     
         6 . The abdominal exercise device of  claim 1 , wherein said two connectors are located on one of a top of the frame and the middle of the frame. 
     
     
         7 . The abdominal exercise device of  claim 1 , wherein the plurality of connectors comprises at least one of a loop connector, a hook connector, and a latch connector. 
     
     
         8 . The abdominal exercise device of  claim 1 , wherein the plurality of connectors comprises a plurality of holes made in the frame of the exercise device for connecting an elastic band. 
     
     
         9 . The abdominal exercise device of  claim 1  further comprising a memory foam pillow attached to an elastic band, the elastic band comprising a first end connected to a first connector located on the middle of the frame and a second end connected to a second connector located on the middle of the frame, the memory foam pillow configured to:
 support the person's chest during a pushup exercise when the abdominal exercise device is turned upside down; and 
 support the person's glute area during a dip exercise when the abdominal exercise device is turned upside down. 
 
     
     
         10 . The abdominal exercise device of  claim 1 , wherein a top of the frame comprises first and second segments configured to change a width of the exercise device, wherein the first segment is hollow and comprises a larger interior diameter than an exterior diameter of the second segment, wherein the first segment comprises a plurality of slots and the second segment a push in button to allow the second segment to fit into a portion of the first segment. 
     
     
         11 . The abdominal exercise device of  claim 10 , wherein the bottom of the frame comprises first and second segments configured to change a width of the exercise device, wherein the first segment of the bottom of the frame is hollow and comprises a larger interior diameter than an exterior diameter of the second segment of the bottom of the frame, wherein the first segment of the bottom of the frame comprises a plurality of slots and the second segment of the bottom of the frame comprises a push in button to allow the second segment of the bottom of the frame to fit into a portion of the first segment of the bottom of the frame. 
     
     
         12 . The abdominal exercise device of  claim 1  further comprising:
 a telephone holder comprising:
 a spring loaded C-shaped frame for holding a cellular phone; 
 a shaft comprising a plurality of segments, wherein an inner diameter of a first section of the shaft is substantially the same as an outer diameter of a second, adjacent, section such that second section telescopically slides within the first section; and 
 a rolling ball connecting the C-shaped frame to the shaft, the rolling ball configured to rotate the C-shaped frame in a vertical plane.
