A forward carrier means, namely, a forward carrier bracket 80 is mounted on the forward support track 12 for carrying a display board on which one or more stretching exercise regimes may be illustrated for the assistance of the subject. In use, the apparatus 1 is suitable for facilitating the performance of many different types of stretching exercises by a subject for stretching the muscles in the limbs of the subject, for example, arm and leg muscles, as well as for stretching the various muscles in the torso. By sitting in the seat 18 and gripping one or more of the forward hand grips 25, the first and second rear hand grips 26, 27 and 29, and/or engaging one or both the feet on the forward foot platform 20 and/or the rear foot engaging members 21 , virtually all stretching exercises which are required for stretching the muscles and tissue of the legs, arms and torso can be carried out. The apparatus 1 is particularly suitable for facilitating the performance of stretching exercises for stretching the following muscle groups: (a) Quadriceps femoris muscle group, rectus femoris, vastus lateralis, vastos medialis, also the ilio psoas. (b) Leg adductors and inward hip rotation. (c) Variation on (2), progression, due to lower hand grip. Slight assistance is applied at about the knee area downward for greater stretch. (d) Shoulder girdle stretch including mid and upper back supraspinatus, infra spinatus, terras minor, subscapularis, elbow flexors, brachialis, brachioradialis. (e) mid to lower back stretch, applying inter abdominal pressure to improve back stretch. (f) Lower back due to increased hip flex position, (g) Total hamstring isolated. (h) Latissimus dorsi stretch, also posterior deltoid and serratus stretch, (i) Pectoralis major and minor also anterior deltoid. (j) Medial deltoid, shoulder girdle any areas involving rotation of the shoulder blade (not shown on diagram) (k) Chest - peck major only, biceps and forearm flexer (with inward grip) (I) Triceps (m) Advanced triceps (n) Straight stretch of leg/calf (gastrocenemius, soleus and achilles tendon). (o) Soleus and achilles tendon isolated. (p) Total back gluteal stretch also some hamstring. (q) Adductor stretch (ITB band) iliotibial band. Use of the apparatus 1 for carrying out exercises for stretching the above muscle groups will be apparent to those skilled in the art. However, Figs. 5 to 16 illustrate a subject undertaking stretching exercises for exercising some of the above muscle groups. Fig. 5 illustrates the subject performing a hamstring stretch of the right leg on the apparatus 1. The subject sits on the seat 18 with the seat facing forwardly and places the right foot on the forward platform 20. The other foot is placed on the ground. The subject grips the forward hand grips 25, and urges the seat and him or herself forwardly along the main track 5 thus urging the forward foot platform 20 upwardly along the forward track 12. This posture is maintained by the subject depending on the level of stretching to which the hamstring is to be subjected. The subject then urges the seat 18 rearwardly along the main track 5, thus lowering the forward foot platform 20 on the forward track 12. The hamstring stretching exercise may then be repeated by the subject urging the seat 18 forwardly and rearwardly along the main track 5, and in turn the forward foot platform 20 upwardly and downwarly on the forward track 12. This exercise is repeated depending on the amount of hamstring stretching is required. The hamstring of the left leg may then be stretched by switching the feet from the foot platform 20 to the ground, and vice versa, and proceeding as described above. Fig. 6 illustrates the subject performing a leg adductors stretching exercise. The subject sits on the seat 18 facing forwardly with his or her feet placed together with the soles of the feet facing each other on the stationary foot platform 22. The upstanding members 58 are gripped by the hands just below the hand grips 25 and the subject pulls his or her body, together with the seat 18 forwardly. Fig. 7 illustrates a triceps extension stretching exercise. In this exercise the subject is seated on the seat 18 with the seat 18 facing forwardly. The subject places his or her two feet on the ground, and grips one of the forward hand grips 25 with the left hand and one of the upper second rear hand grip 27 with the right hand. The body is kept in an upright position and the subject pulls forward on the forward hand grip 25 thereby stretching the triceps extension. By switching hands so that the right hand grips the other forward hand grip 25 to the left hand grips the upper second rear hand grip 27 the other triceps extension muscle is exercised. Rotation of the body by allowing the seat 18 to swivel further enhances this exercise. Fig. 8 illustrates a stretching exercise for the pectoralis muscle. The feet are placed on the ground, and both arms are extended rearwardly and the two hands grip the lower second rear hand grips 29. The subject urges him or herself forwardly on the seat 18 along the main track 5. Fig. 9 illustrates an exercise for stretching the latissimus dorsi muscle. With the seat 18 facing sidewardly, the first rear hand grip 26 is pivoted into a desired position and locked therein by the locking pin 70. The subject then grips the first rear hand grip 26 with the left hand and the upper second rear hand grip 27 and urges him or herself forward on the seat 18 along the track thereby stretching the latissimus dorsi muscle. The subject by swivelling the seat 18 through 180° to face outwardly from the opposite side of the main track 5 can repeat the exercise with the hands switched between the first rear hand grip 26 and the upper second rear hand grip 27. Fig. 10 illustrates a medial deltoid muscle stretch exercise in this exercise the subject maintains the same position as illustrated in Fig. 9 but instead of stretching the right arm over the head to grip the upper second rear hand grip 27 the subject extends the right arm across his or her chest. By urging the seat 18 forwardly along the main track 5 the stretching of the medial deltoid muscle is increased, and the shoulder girdle and the S.I.T.S. muscle groups are also stretched. Similarly, the seat 18 may be swivelled through 180° for carrying out the stretch on the other side of the body, with the hands switched between the hand grips 26 and 27. Fig. 11 illustrates a gastrocenemius stretch or upper calf muscle stretch of the right leg of the subject. In this stretch the locking pin 76 of the appropriate rear foot engaging member 21 is released for facilitating free pivotal movement of that rear foot engaging member 21. The subject seated on the seat 18 with the seat 18 facing rearwardly places the right foot on the corresponding rear foot engaging member 21. The subject grips the first rear hand grip 26 and with the knee kept straight downward pressure is applied to the heel for pivoting the rear foot engaging member 21 against the resilient urging force of the spring 75. The upper calf muscle of the left leg is similarly stretched on the other of the two rear foot engaging members 21. Fig. 12 illustrates a lower calf muscle stretching exercise of the right leg of the subject isolating and stretching the soleus and achilles tendon area. In this exercise, the subject sits on the seat 18 with the seat 18 rearwardly facing, and operates the locking pin 76 for locking the appropriate rear foot engaging member 21 in the position illustrated in Fig. 12. The subject places his or her right foot on the corresponding rear foot engaging member 21 , grip the first rear hand grip 26 with both hands, and urges his or herself forwardly on the seat 18 along the main track 5. Fig. 13 illustrates the subject performing an upper back stretch exercise. The subject sits in the seat 18 with the seat 18 facing rearwardly. The locking pins 76 are operated for locking the rear foot engaging members 21 in the position illustrated in Fig. 13. The subject places his or her feet on the respective rear foot engaging members 21. The subject grips the first rear hand grip 26 and with his head bowed downwardly urges his or her body rearwardly, and in turn the seat 18 rearwardly along the main support track 5 for thus stretching the upper back muscles. Fig. 14 illustrates a subject performing a lower back stretch exercise. The subject adopts a substantially similar posture for carrying out this stretch exercise as the posture adopted in Fig. 13, with the exception that instead of gripping the first rear hand grip 26, the subject grips the upper portion of the respective foot engaging members 21 by hand as illustrated in Fig. 14. This, thus, causes the subject to bend the lower back forward. The subject urges his or her body and in turn the seat 18 rearwardly along the main support track 5 for thus stretching the lower back muscles. By tilting the seat 18 rearwardly, in other words by tilting the seat 18 so that the front of the seat portion 35 is raised relative to the back of the seat portion 35, stretching of the lower back muscles is increased. Fig. 15 illustrates a stretch exercise for the hip flexor muscle. In this exercise the subject stands with the left foot on the ground, grips one of the forward hand grips 25 with the left hand and the top of the backrest 36 of the seat 18 with the right hand. The locking pin 76 is operated so that the appropriate rear foot engaging member 21 is free to pivot, and with the toe of the right foot facing downwardly the right foot is placed on the rear foot engaging member 21. Pressure is applied by the ball of the right foot to the rear foot engaging member 21 for urging the rear foot engaging member against the resilience of the torsion spring 75. The subject moves to the other side of the apparatus 1 for further stretching the hip flexor by adopting a similar stance but with the hand switched and the feet switched. Fig. 16 illustrates a stretch exercise for the quadriceps or front of thigh stretch of the left leg of the subject. In this exercise the upstanding members 58 of the forward hand grips 25 are locked in a substantially vertical position. The seat 18 is swivelled to face rearwardly. The subject stands with the right foot on the ground to one side of the apparatus 1 and gripping the respective forward hand grips 25. The height of the foot support 47 is adjusted along the track 48 on the rear of the backrest 36. The left foot is raised and placed in the foot support 47. The hips are dropped until the stretch is felt in the front of the thigh of the leg on the ground. The front thigh of the right leg is stretched by moving to the other side of the apparatus 1 , and switching the feet between the ground and the foot support 47.
