Abstract
An exercise system includes a rowing exercise device and a chair. The rowing exercise device achieves a lower limb exercise which includes repetitive extension and flexion of at least a knee joint and a hip joint. The chair is the one on which a user who performs the lower limb exercise using the lower limb exercise device sits. The chair includes a seat on which the user sits and a support mechanism capable of supporting the seat in such a manner that the seat can carry out a roll oscillation. The seat carries out a roll oscillation during the lower limb exercise, which causes a motion linkage between a lower limb and a trunk.
