Disclosed is a device to aid in spreading a person's legs to increase the flexibility of the groin and thigh muscles. The device employs a bar having a central curved segment that engages the lower back region. Each end of the bar has a pulley through which a cord extends with a handgrip and a stirrup at opposite ends of the cord. The user sits on the floor and places their feet through the respective stirrups, and pulls on the handgrips which pull the feet to spread the legs.

What is claimed is: 1. A leg-stretching device comprising: a bar having a curved center segment to be positioned adjacent the lower back of a person using the device with end segments extending outwardly; a pulley connected to a first end segment of the bar; a cord extending over the pulley with a

What is claimed is: 1. A leg-stretching device comprising: a bar having a curved center segment to be positioned adjacent the lower back of a person using the device with end segments extending outwardly; a pulley connected to a first end segment of the bar; a cord extending over the pulley with a handgrip connected to one end of the cord and a stirrup connected to an opposite end of the cord; and a second pulley connected to a second end segment of the bar, a second cord extending over the second pulley, a second handgrip connected to one end of the second cord and a second stirrup connected to the opposite end of the second cord, wherein the bar center segment is configured to conform to the lower back portion of the person using the device, and wherein the bar end segments have a curvature opposite to that of the center segment. 2. The device of claim 1 comprising one or more hinges connected to the bar to enable the bar to be collapsed for handling and storage. 3. A leg-stretching device comprising: a bar having a curved center segment between two curved end segments; the segments all having substantially the same radius of curvature, wherein the center segment has a curvature opposing that of the two end segments; a pivot connected to each end segment; a cord for each end of the bar and each being movably connected to each pivot; a handgrip connected to one end of each cord and a stirrup connected to an opposite end of each cord and arranged so that pulling on the handgrips moves the stirrups away from each other. 4. The device of claim 3 wherein each pivot comprises a pulley and each cord extend onto the pulley. 5. The device of claim 4 wherein each pivot further comprises a lock for clamping each cord to prevent movement of the cord on the pulley. 6. A leg-stretching device comprising: a bar with a curved center segment located between two curved end segments; the curved center segment having a tangential connection to each of the two curved end segments; and two cords, one being moveably connected to an outer end of one end segment and the other being moveably connected to an end of the other end segment; each cord having a handgrip connected to one end of the cord and a stirrup connected to an opposite end of the cord. 7. The device of claim 6 including a pulley attached to each end of the bar for receiving a respective one of said cords. 8. The device of claim 7 including a cord lock on each end of the bar. 9. A leg-stretching device comprising: a bar having a curved center segment between two curved outer segments, the center segment having an opposing curvature to the two end segments; each of the end segments having a longer circumferential length than the center segment; a pivot on each of the outer curved segments; and a cord moveably connected to each pivot and having one end to be pulled by a user's hand and an opposite end to be connected to a user's foot, whereby pulling on the cords with the user's hands will provide forces to spread the user's legs. 10. The leg-stretching device of claim 9 wherein each pivot comprises a pulley and each cord is moveably connected to the pulley. 11. The leg-stretching device of claim 10 wherein each pivot further comprises a lock for holding the cord in a selected position. 12. A method for stretching a pair of legs comprising: placing the person in a seated position on a floor; positioning a center segment of a bar of a leg stretching device against a person's lower back with outer curved outer segments of the bar extending away from the person; placing the person's right foot into a right stirrup which is connected to a right end of the bar through one end of a first cord moveably connected to the bar; placing a left foot into a left stirrup which is connected to a left end of the bar through one end of a second cord; grasping an opposite end of the first cord with the person's right hand; grasping an opposite end of the second cord with the person's left hand; and pulling on the cords with the person's hands causing the person's feet to be spread in a leg stretching position. 13. The method of claim 12 comprising locking the cords in selected positions to hold the person's feet in a selected leg stretching position. 14. The method of claim 13 comprising unlocking the cords from the locked positions.
