Abstract
A rowing exercise device includes: a pair of pedals; and a device body that guides the pair of pedals in such a way that the pair of pedals repeatedly move along a predetermined trajectory. A user performs a lower limb exercise by putting his/her feet on the pair of respective pedals. Each pedal is configured in such a way that a relative roll turn of a forefoot part relative to the device body is prevented while a relative roll turn of a rearfoot part relative to the forefoot part is allowed, whereby a relative roll turn of the forefoot part relative to the rearfoot part occurs during the lower limb exercise.
