     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to  FIGS. 1 to 4 , which respectively are a perspective view, exploded view, side view and partly enlarged view, the present invention, as the figures show, mainly includes a base  1 , which includes a first connection portion  11  and base body  12 , where at least one first connection hole  111  is configured at a predetermined position of the first connection portion  11  and at least one first fixing element  121  is configured on the middle-rear section of the base body  12 , the first fixing element  121  being engaged with the first connection hole  111  to connect the first connection portion  11  with the base body  12 . 
     A first support element  2  perpendicular to the base body  12  is configured on the middle-front section of the base  1 , and at least one second fixing element  21  is configured on the middle-upper section of the first support element  2 . Furthermore, one end of the first support element  2  is in connection with a second connection portion  3 , and at least one second connection hole  31  is configured at a predetermined position of the second connection portion  3 , the second connection hole  31  being engaged with the second fixing element  21  to connect the second connection  3  with the first support element  2 . In addition, one end of the second connection portion  3  is coupled pivotally to a back rest  4 , and at least one elastic element  41  is configured on the position where the back rest  4  is coupled pivotally to the second connection portion  3 . 
     A second element  4  perpendicular to the base  1  is configured on the base  1  by coupling one end of the second support element  5  to the middle section of the base  1 , and the other end of the second support element  5  is in connection with at least one pivoting body  51 , one end of which is coupled pivotally to a seat cushion  6 . 
     A third support element  7  perpendicular to the base  1  is configured on the middle-rear section of the base  1 , and a third fixing element  71  the middle-upper section of the third support element  7 . Furthermore, one end of the third support element  7  is in connection with a third connection portion  8 , and at least one third connection hole  81  is configured at a predetermined position of the third connection portion  8 . In addition, at least one support body  9  is configured at a predetermined position of the third connection portion  8  and third support element  7 . 
     The middle-rear, middle and middle-front sections of the first connection portion  11  mentioned above are respectively configured with the first connection hole  111 , all the first connection holes  111  being spaced apart from each other on the first connection portion  11 . 
     The second connection hole  31  is configured at an arbitrary position of each of the middle-lower, middle and middle-upper sections of the second connection portion  3  mentioned above, all the second connection holes being spaced apart from each other on the second connection portion  3 . 
     The elastic element  41  mentioned above is a spring. 
     At least one bearing  511  is further configured inside the pivoting body  51  mentioned above. 
     The third support element  7  mentioned above is configured on the middle-rear section of the base  1 , and the third fixing element  71  the middle-upper section of the third support element  7 . 
     The third connection hole  81  is configured at an arbitrary position of the middle-lower, middle and middle-upper sections of the third connection portion  8  mentioned above. 
     As the third connection portion  8  mentioned above, the support body  9  is configured at an arbitrary position of the middle-lower, middle, middle-upper sections of the third connection portion  8  and third support element  7 . 
     As the support body  9  mentioned above, furthermore, at least one cotton body  81  is respective put around the two sides of the support body  9 . 
     Referring to  FIGS. 5 and 6 , which respectively are a perspective view of the present invention upon the contraction and stretching thereof, as the figures show, the first, second and third fixing element  121 ,  21 ,  71  are respectively released from the first, second and third connection holes  111 ,  31 ,  81 , and the firs connection portion  11  is then moved rightward, the second connection portion  3  upward\, and the third connection portion  8  upward. Thereafter, the first, second and third fixing elements  121 ,  21 ,  71  are respectively engaged with the other first, second and third connection holes  111 ,  31 ,  81  again, thereby contacting or stretching the present invention effectively to conform to the users&#39; requirements. 
     Referring to  FIG. 7 , , which is a perspective view of the present invention while the seat cushion is being put into use, the seat cushion  6 , as the figure shows, is allowed to be rotated freely through the pivotal coupling of the seat cushion  6  to the pivoting body  51 . Whereby, a user can turn around through the seat cushion  6  so as to exercise their abdomen and waist while they sit on the seat cushion  6  and put their hands on the support body  9 . 
     Referring to  FIG. 8 , which is a perspective view of the present invention while a user is doing a trunk extension exercise, a user, as the figure shows, puts their back on the back rest  4  and their hips on the seat body  6 , with their feet being placed on the support portion  9 . Whereby, the back rest  4  is caused to be inclined rearward through the pivotal coupling of the back rest  4  to the second connection portion  3  when the user throws their back rearward, and the back rest  4  is then supported effectively through the elastic element  41  configured at the position where the back rest  4  is coupled pivotally to the first connection portion  11 , with the back rest  4  being sprung back forward through the resilient force of the elastic element  41 , allowing the use&#39;s body to be inclined forward to recover back to the original posture before the back throwing-back in such a way to exercise their abdomen and stretch their muscles and bones by repeating the action mentioned above. 
     Referring to  FIG. 9 , which is a perspective view of the present invention while a user is doing a sit-up exercise, a user, as the figure shows, put their legs on the support body  9  and their hips on the seat cushion  6 . Whereby, the use&#39;s body can be recovered back to the original sitting posture by supporting the legs with the support body  9  after the user inclines their body rearward to lie on the back rest  4  in such a way to exercise their abdomen by repeating the action mentioned above.
