Abstract: A chair includes a seat (2) and also includes a pair of thigh support elements (17) pivotal n a generally downwardly direction about front pivot axes (20) from a first state forming with a central seat element (15) a substantially common plane, to a second downwardly extending state. The elements (17) are also pivotal about second pivot axes in a generally rearwardly direction for urging the user's thighs away from each other for stretching the adductor muscles. Foot support members (49) extend transversely and sidewardly on respective opposite sides of the chair (1) from a support element (46) for supporting the foot during a stretching exercise with the corresponding thigh of the subject extending downwardly from the seat (14) and the lower leg extending from the knee in a upwardly inclined direction to the foot support member (49) for stretching the quadriceps and the hip flexor muscles of the subject.
