The exercising apparatus has a body support against which the torso of a person using the apparatus mainly rests. The apparatus also has first, upper support means (2; 22; 32) for the person's upper extremities and second, lower support means (3; 23; 33) for the person's lower extremities. The apparatus has drive means (9; 39) for moving the upper and lower support means so that the person's extremities, starting from a rest position (A) are imparted a movement outwardly from the sides of the torso and upwardly towards the person's head, along parts of circular paths, to a turning point (B) and thereafter back to the rest position (A).
