A chair (1) for carrying out leg stretching exercises by a subject seated thereon comprises a seat (9) formed by a main seat element (17) and a pair of thigh support elements (35) extending from the main seat element (17). The thigh support elements (35) are pivotal in a generally downwardly direction about respective horizontal first pivot axes (37) from a first state for supporting the corresponding thigh of a subject to a second downwardly extending state with the thigh of the subject unsupported. The thigh support elements (35) are also pivotal about respective substantially vertically extending main pivot axes (45) in a generally rearwardly direction away from each other from a normal forwardly extending state to a stretching state for urging the thighs of a subject supported on the thigh support elements (35) away from each other for stretching the adductor muscles. A pair of foot support elements (13) extend transversely and sidewardly on respective opposite sides of the chair (1) from a carrier element (16) for engaging the instep of a corresponding foot of a subject for supporting the foot during a stretching exercise of the quadriceps and hip flexor muscles with the corresponding thigh of the subject extending generally downwardly from the seat (9) and the lower leg extending from the knee in a generally rearwardly upwardly inclined direction to the foot support element (13).
