The processor is configured to acquire the movable part attitude information while the exerciser is moving the body along the trajectory, acquire current muscle activity information for each of the muscle sites based on current movable part attitude information of the training equipment and the muscle activity database, and output the current muscle activity information for each of the muscle sites.

Abstract: A lower limb exercise device that enables a user to perform a lower limb exercise effectively is achieved. A lower limb exercise device according to one embodiment of the present disclosure enables a user to perform a lower limb exercise while the user is seated on a chair. The lower limb exercise device includes exercise equipment for the user to perform the lower limb exercise, and a restriction mechanism configured to restrict movement of at least one caster of the chair from a reference arrangement range of the caster during the lower limb exercise.

Abstract: A chair includes: two coxal bone support balloons that support two coxal bones respectively; and a sacral bone support balloon that supports one of a sacral bone and a coccygeal bone. The two coxal bone support balloons are configured to be able to rock relative to the sacral bone support balloon.

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.
