An apparatus (1) for automated walking oder treadmill training of a user comprises a frame or treadmill (10) having a driven treadmill belt (12), a pelvis attachment (50) to support the position and/or weight of the user and having attachment elements (52) adapted to be connected to the user. The pelvis attachment (50) comprises a displacement unit for allowing a movement of the pelvis of the user held by the attachment elements (52) transverse to and/or rotating about a perpendicular axis to the walking direction (500) provided by the treadmill (10) to provide a more natural and physiological gait during training. A weight suspension unit (40) having a cable (43) guided over a guide roller (45) positioned above the pelvis attachment (50) opposite to the treadmill (10) and attached to the pelvis attachment (50) can comprise a weight suspension roller displacement unit (48) adapted to move the guide roller essentially perpendicular to the main alignment direction of the cable (43) to influence the transverse position of the upper body of the person to be trained as well as to prevent a pendulum effect of the trunk of the user.
