The front ends of thebeams 11 may be secured to therear panels 14 of thebrackets 13 respectively withfasteners 17, for supporting thebeams 11 at the upward working position. A seat cushion or aseat 16 is disposed on thebase 10, such as on the upper portion of thebeams 11 for supporting the buttocks or the knees of the users. - A
back frame 20 includes a lower portion pivotally secured on thebase 10 with apivot axle 23, for allowing theback frame 20 to be rotated or pivoted relative to thebase 10. For example, theback frame 20 includes a pair ofarms 21 provided in the bottom portion thereof and parallel to each other for supporting the arms of the users, and includes one or two pairs ofbrackets 22 secured to the bottom portion of theback frame 20, or secured to thearms 21 respectively, for supporting thepivot axle 23 and for pivotally coupling theback frame 20 to thebase 10. Thebrackets 22 each includes one ormore apertures 24 formed therein and preferably formed around thepivot axle 23. Apad 28 is secured to theback frame 20 for engaging with the back portion of the users. - A
lever 30 includes twolegs 37 each having an upper end pivotally or rotatably secured to thebase 10 with thepivot axle 23, and rotatable relative to thebase 10 about thepivot axle 23. One or twofasteners 38 may engaged with either of theapertures 24 of thebrackets 22 and may engage with thelegs 37 of thelever 30 respectively for adjustably securing thelever 30 to thebrackets 22 of theback frame 20 and for selectively securing thelever 30 to theback frame 20 and for allowing thelever 30 to be rotated in concert with theback frame 20. - A
follower tube 31 includes a rear port ion pivotally secured to abracket 33 of thelever 30 with apivot shaft 39 and includes a front portion slidably supported on the front portion of thebase 10 with aroller 47 or the like. Arod 40 is slidably engaged in thefollower tube 31 and selectively or adjustably secured to thefollower tube 31 with afastener 41 or the like for allowing therod 40 to be adjusted inward and outward relative to thefollower tube 31. Therod 40 includes afoot support 44 secured or provided thereon. Aspring biasing device 48 includes one or more spring members coupled between thebase 10 and thefollower tube 31 or therod 40 or thefoot support 44 for applying a biasing force against thefollower tube 31 and thus therod 40 and thefoot support 44. - In operation, as shown in FIGS. 4 and 5, the user may engage his back on the
back frame 20 to rotate theback frame 20 about thepivot axle 23 and to exercise his back portion or his waist portion, and may engage his feet on thefoot support 44 in order to move thefoot support 44 and therod 40 and thefollower tube 31 forward against the spring or thebiasing device 48, and to exercise his feet portion. Thebiasing device 48 may bias thefoot support 44 rearward and may thus bias, via thelever 30, theback frame 20 to the upward or erect position as shown in FIGS. 1-4. - The
