         7 . The exercise device of  claim 5 , wherein at least one end of the frame is connected to a corresponding side rail via a spring device comprising at least one spring, and wherein the base comprises three foldable sections, a length of the side rails being equal to a length of each side of a central section of the three foldable sections. 
     
     
         8 . The exercise device of  claim 1 , wherein the base comprises foldable sections, and wherein the base is configured to be overlaid on a chair by folding the foldable sections, and wherein each of a back portion of the chair and a legs portion of the chair is perpendicular to a seating portion of the chair. 
     
     
         9 . The exercise device of  claim 1 , wherein the base includes a bulging portion that is inflatable. 
     
     
         10 . The exercise device of  claim 1 , wherein the base comprises a back-support device in a central portion of the base, and wherein the back-support device is configured to provide support to a lower back of a user. 
     
     
         11 . The exercise device of  claim 5 , wherein at least one end of the frame is connected to the side rails via a screwing mechanism. 
     
     
         12 . The exercise device of  claim 1 , wherein the grip is located on an external surface of a weights device configured to slide along the frame, the weights device comprising one or more stacks of weights that are interlocked via a screwing mechanism using at least one screw and that are enclosed by a rubber coating. 
     
     
         13 . The exercise device of  claim 1 , further comprising:
 at least two straps extending from a swivel connecting the frame and the grip, each strap configured to allow a user that is laying down to perform the exercise to place a corresponding foot within the strap.   
     
     
         14 . The exercise device of  claim 1 , wherein the grip forms an outer surface of at least one handle that is configured to slide on the one or more curved poles of the frame, the handle being configured to be rotated around an axis of the frame in order to flip the handle to an upside down orientation, the handle comprising two curved sections, each curved section configured to be held by a separate hand of the user. 
     
     
         15 . A method for assembling an exercise device, the method comprising:
 connecting a frame having a shape of an arc to a base, the base configured to allow a user to lay down while performing an exercise, the base being connected to two ends of the frame such that the base and the two ends of the frame are substantially equidistant from a bottom surface of the base when the user is performing the exercise; and   connecting a grip to the frame, the grip configured to slide along the frame, the grip forming an outer surface of at least one of a weights device and one or more handles, the grip being configured to be held while performing an exercise.   
     
     
         16 . The method of  claim 15 , wherein the weights device is either a medicine ball or a plurality of discs with corresponding weights. 
     
     
         17 . The method of  claim 15 , further comprising:
 attaching at least one stopper on the frame to limit a length of the frame along which the grip is allowed to slide; and   attaching two straps to the one or more handles in an upward direction when the weights device is in a downward direction, each strap allowing a user to place feet within the two straps.   
     
     
         18 . The method of  claim 15 , further comprising:
 rotating the weights device along an axis of the frame so as to diametrically flip the one or more handles, the diametrically flipped one or more handles allowing a user to place feet in at least one of the one or more handles.
