The invention relates to a training device for stimulating and training the locomotor system of a person. Said training device comprises a pivotable seesaw (16) that supports the person and that pivots in relation to a seesaw stand (19, 20, 21, 22), a drive device comprising at least one motor (2) and a gearing comprising gearing elements (5, 6, 7, 11, 12, 13, 14, 14'). Said gearing elements (5, 6, 7, 11, 12, 13, 14, 14') form at least one power-transmission chain between the seesaw (16) and the motor (2) and at least one gearing element (14, 14', 29) is elastically connected to the seesaw (16) or to a lifting element (28) that is securely fixed to the seesaw (16). The invention also relates to a training device in which the seesaw (16) is elastically held in relation to the seesaw stand (19, 20, 21, 22).
