8. The adjustment device according to claim 2 , wherein said control means interacts with a scale member attached to the frame of the training machine, such that when turning said control means a desired position on the scale member can be set.
9. The adjustment device according to claim 3 , wherein said control means interacts with a scale member attached to the frame of the training machine, such that when turning said control means a desired position on the scale member can be set.
10. The adjustment device according to claim 5 , wherein at each of said laterally adjusted positions of said arms is a hole provided in said scale member which is fixed to a frame portion of the training machine.
11. The adjustment device according to claim 1 , wherein said arm rest members include pads to contact both the user's arms and elbows.
12. An adjustment device for a training machine, especially a triceps extension or a biceps curl, for strengthen training and rehabilitation, having an arm rest member positioned to contact and rest a user's arm and pivotably connected handles provided on each side of a seat, wherein said arm rest members and said handles are provided at lower ends of arms arranged at both sides of said seat, the arms being pivotably suspended at a position at a top of said training machine such that said adjustment device comprises control means for laterally adjusting positions of said arms, said arm rest members, and said handles with regard to said seat, and
a control member which can be set in a selected position of a pre-determined number of positions corresponding to the laterally adjusting positions of said arms, said arm rest members, and said handles,
wherein said adjustment device further comprises a linkage means at each side of said adjustment device, each of the linkage means being connected at one end thereof to a turnable link member, which is pivotably fastened at its center at a frame portion of the training machine, and at the other end to said arms.
13. An adjustment device for a training machine, especially a triceps extension or a biceps curl, for strengthen training and rehabilitation, having an arm rest member positioned to contact and rest a user's arm and pivotably connected handles provided on each side of a seat, wherein said arm rest members and said handles are provided at lower ends of arms arranged at both sides of said seat, the arms being pivotably suspended at a position at a top of said training machine such that said adjustment device comprises control means for laterally adjusting positions of said arms, said arm rest members, and said handles with regard to said seat,
