The instrument according to claim 1 or 2.   The instrument of claim 5, wherein the seat portion is positioned between a first end of each of the backrest and legrest.   The instrument according to any one of claims 1 to 6, wherein the support portion includes a handle that is grasped by a user during an exercise operation.   8. The pivot connection of the backrest and footrest, respectively, such that each can be pivoted to at least a substantially horizontal position against the elastic bias. Instruments.   The instrument according to claim 8, wherein the backrest and the legrest can be pivoted to a position beyond the horizontal against the elastic bias so that each of them tilts downward from the seat portion.   The instrument according to any one of claims 1 to 9, wherein the legrest is configured to support a back side of a user's thigh.   11. The backrest comprises an arm member, the arm member elastically pivotally engaged with the support and comprising at least one cushion pad for application to a user's back. The instrument according to any one of the above.   12. Apparatus according to claim 11, wherein the at least one cushion pad for application to a user's back is preferably able to move in a rolling manner.   13. A device according to any one of the preceding claims, wherein the footrest comprises at least one central longitudinal arm, with footrest means extending laterally on each side of the arm.   The instrument according to claim 13, wherein the footrest means comprises a cushion member.   15. An instrument according to claim 13 or 14, wherein the cushion support member is configured to rotate relative to each other such that the cushion support member rotates when a user's leg is moved relative to the cushion support member.   16. An instrument according to claim 13, 14, or 15, wherein each first and second pair of support members is provided spaced apart in the longitudinal direction of the central arm (s).   14. The footrest means is movably attached to the longitudinal arm (s) so that the position on the arm (s) can be adjusted as needed. The instrument of claim 14, 15, or 16.   The instrument according to any one of claims 1 to 17, wherein the legrest comprises left and right members pivotally attached.   The instrument of claim 18, wherein the left and right members are configured to pivot independently.   20. An instrument according to claim 18 or 19, wherein the left and right members are configured with selectively detachable coupling means so as to achieve selective pivoting as a single unit or independent pivoting.   21. A device according to any preceding claim, wherein the footrest is configured to be coupled to an elastically biased intermediate member for the pivoting.   The instrument of claim 21, wherein the position of the coupling of the footrest to the intermediate member can be selectively changed.
