     FIELD OF THE INVENTION 
       [0002]    The present invention relates generally to devices using dynamic movement of one&#39;s body. The invention may be used for shoulder, hip, knee, back, thigh and abdominal musculature and the like. The invention relates more specifically to a device and method for exercising and developing greater flexibility of the spinal column and the muscles of the torso, including those in the abdominal lumbar and thoracic regions involving rotational torque in a function posture. 
       BACKGROUND OF THE INVENTION 
       [0003]    In a general embodiment, the invention relates to an exercise and flexibility apparatus that may keep the body in good shape. In a preferred embodiment, the invention relates to a golf exercise and flexibility apparatus, and particularly to golf exercise apparatus which provides resistance to a golfer during a golf swing to strengthen and condition the muscles of the axial skeleton of the golfer. 
         [0004]    While this invention is described in terms of exercise and golf, the device may be used broadly for general conditioning, physical therapy and other sports such as swimming, tennis and the like where conditioning and flexibility are desirable. In one embodiment, this invention helps to prevent or minimize minor muscle aches and pains. 
         [0005]    Currently, golf is an activity enjoyed by many people of all ages possessing varying degrees of athletic ability, musculoskeletal strength, flexibility and endurance. Although it is possible to perform a golf swing without having excessive musculoskeletal support, greater bodily strength, flexibility and endurance allows a golfer to hit a golf ball farther and with greater accuracy and consistency and to minimize minor muscle related aches and pains. 
         [0006]    External devices are currently being marketed to help train the muscles of the golfer to move along a predetermined path which is thought to be along an optimal golf swing path. These devices restrict the swing path of the golfer to a plane within which it is thought necessary to maintain the golf club throughout the golf swing. However, no resistance is supplied in the direction of rotation of the shoulders and upper torso, the hips, and upper legs of the golfer during performance. These devices are not designed to benefit muscular conditioning or flexibility. 
         [0007]    Regular exercise may keep the body in good shape, but not all exercise is equally effective. Many exercise devices on the market, particularly in health and athletic clubs, are less effective than patrons may assume, particularly as related to the rotational movements required in golf and similar activities. The problem is that most available equipment in health clubs train in predominantly linear, single plane movement and are limited to isolating one muscle group. The body rarely moves in just one plane and often requires multiple muscle groups to work together. Most body movement involves rotation and diagonal patterns of movement. 
         [0008]    The need exists for an exercise, conditioning and rehabilitation device which permits activity consisting of components of motion in all three planes, and permits isolation of a specific area of the body, the motion of which is most desired. Such a device will permit a physical therapist, chiropractor or trainer or other instructional devices to tailor the activity of the user to the goals of the user. 
       SUMMARY OF THE INVENTION 
       [0009]    The device of this invention is a golf exercise and conditioning apparatus that provides resistance during an exercise emulating the movements required of a golf swing of a golfer to strengthen and condition the muscles of the axial skeleton and lower extremities of the golfer performing the exercise. The device includes a support base; a member pivotally mounted to the support base; a torso pivotally mounted axial shaft coupled to the pivotally mounted member; and a pelvis pivotally mounted axial shaft coupled to the pivotally mounted member. A shoulder harness is connected to the torso axial shaft; and a hip harness is connected to the pelvis axial shaft. A torso, independent torque resistor is connected to the torso axial shaft and includes a means for providing resistance in at least two directions. 
         [0010]    A pelvis, independent torque resistor also is connected to the pelvis axial shaft, and includes a means to provide resistance in at least two directions. In a preferred embodiment, the apparatus includes a means to independently lock the torso shaft in a neutral position and a means to independently lock the pelvis shaft in a neutral position. 
         [0011]    The advantage of this new device is that it offers user-determined variable resistance in a standing, functional position. The inclination angle from the vertical can be modified by the user to better replicate posture in various sports such as golf, hockey, or baseball. Other devices designed to enhance trunk muscle rotator strength, places the user in a seated position which restricts pelvic motion and distributes a greater proportion of the imposed stress to the vertebrae, thereby increasing the potential for injury. The invention provides resistance to trunk and pelvic rotation without restricting the natural rotational movement of the trunk and pelvis. The present devices do not allow the user to undertake strength exercises in a functional posture at all. 
         [0012]    The exercise apparatus of this invention provides resistance in a direction of movement and resistance in a direction opposite of movement. The apparatus comprises means to provide the movement; means to control the resistance; and means to manage the movement. The method that provides resistance in a direction of movement and resistance in a direction opposite of movement comprises the steps of providing an exercise apparatus; locating a user in the apparatus to provide movement; providing resistance to the movement; controlling the resistance to the movement; and managing the movement. 
         [0013]    Other objects and advantages of the present invention will become apparent to those skilled in the art upon a review of the following detailed description of the preferred embodiments and the accompanying drawings.

         [0046]    In one embodiment, we employ a computer chip that tracks all aspects of performance over time. In this embodiment, a means measures at least one or all aspects of performance and converts the performance into an electrical signal representative of the performance being monitored. A programmed microprocessor including the computer chip is configured to identify the signal representative of the performance being monitored. The programmed microprocessor also is configured to identify and store the parameter (performance) being monitored. This enhanced version allows the professional to track their students. It also is used for the physical therapist and chiropractor to monitor a patient. 
         [0047]    In another embodiment, shoulder harness  22  is not a true harness connected to a user&#39;s shoulders by a means such as a strap or belt. Preferably, shoulder harness  22  has a distal end with handles attached thereto. The user grasps the handles during use of apparatus  10 . 
         [0048]    In still another embodiment, base  14  includes sensors which provide signals to the programmed microprocessor. These, for example, would help a PGA Professional, to monitor a student&#39;s weight shift during a golf swing. Knowing if a right handed golfer&#39;s weight is on the inside of the right foot at the top of the back swing would be a valuable teaching tool. Monitoring a weight shift to the outside of the left foot at the completion of the follow through would be equally valuable. 
         [0049]    The above detailed description of the present invention is given for explanatory purposes. It will be apparent to those skilled in the art that numerous changes and modifications can be made without departing from the scope of the invention. Accordingly, the whole of the foregoing description is to be construed in an illustrative and not a limitative sense, the scope of the invention being defined solely by the appended claims.
