Title: Exercise apparatus for strengthening the hips and associated musculature

Description:
TECHNICAL FIELD AND BACKGROUND OF THE INVENTION 
     This application discloses an exercise apparatus for strengthening the hips. The invention has application in both the sports and health fields. For purposes of the disclosure of the invention in this application, the descriptions will be oriented towards the sports field, and particularly golf, but other activities such as baseball and tennis will also benefit. Golf is a sport in which the level of exertion and articulation of various body parts varies between extremes. When teeing off, and particularly when using a driver or other long-distance club, there is a direct correlation between the speed at which the clubhead strikes the ball and the distance the ball travels. All else being equal, the further a ball travels off of the tee, the better. 
     Clubhead speed is a function of two simultaneous motions. In the first motion, the club is swung by the player by gripping the club with the hands and taking the club back using the arms, “the backswing” or “takeaway”, and then swinging the club forward, the “downswing”, with the arms on an arc designed to place the center of the clubface squarely on the ball at impact. However, if the golfer stands still with the legs, hip and torso relatively motionless and swings only with the arms, the ball will travel only a relatively short distance. This may be a highly desirable technique for putting, chipping and pitching where finesse, feel and precision are more important than distance. However, this first motion is not calculated to maximize the distance the ball travels when struck. 
     So, a skilled golfer will strike the ball with a combination of body movements calculated to maximize the speed of the clubhead at impact with the ball. The second body movement involves use of the legs, hips and torso. In general, the hips act as a torsion spring and rotate to allow the upper body, particularly the shoulders, to assume during the backswing an approximate right angle to the direction of desired ball travel, while the legs flex and bend to some degree but remain generally aligned with the direction of desired ball travel. 
     Meanwhile, the arms have rotated rearwardly and upwardly so that at the top of the backswing the hands and the grip of the club are positioned well above the trailing shoulder. At the top of the backswing, the golfer reverses the direction of rotation in a controlled, accelerating manner, causing the body from the shoulders down through the hips to rotate back through the original address position and then continue further rotation until the shoulders have rotated perhaps as much as 180 degrees or more from the top of the backswing position. 
     At the same time as the body is rotating from the top of the backswing the arms are also moving downwardly so that the clubhead travels through the ball position and continues on to the “follow through.” The speed of the clubhead is the aggregate of the speed of the arm motion and the hip/torso motion, and the more rapidly both of these motions simultaneously occur the more potential energy is available to be transferred to the ball by the clubhead. 
     To maximize the potential for a clubhead speed that includes a rapid hip rotation, exercise directed towards strengthening the hips and associated musculature is desirable. The most desirable exercise is exercise that not only strengthens the musculature but at the same time trains the muscles to expect resistance when being asked to do work. Within the golf swing context, if the muscle expects for there to be substantially more resistance than actually occurs, the muscle will naturally exert more force, increasing torso rotation speed which is added to the arm swing speed to result in an increased club head speed when the ball is struck. 
     Golf instructors refer to the proper sequence of body motions as the “kinematic sequence.” The proper sequence, as demonstrated by professional golfers and skilled amateurs, begins from the ground up: pelvis/hips, followed by thorax, arms, hands, and finally clubhead. Typically, unskilled amateur golfers reverse this sequence. 
     In this application the term “hip musculature” is used to mean the Gluteus Medius, Abdominal External Oblique, Adductur longus, Brevus and Magnus, Rectus Abdominis and Tensor Fasciae Latae muscles, although other muscles will be affected, as well.

     DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT AND BEST MODE 
     Referring now to the drawings, an exercise and training apparatus  10  for strengthening and training the hips and associated musculature is shown. The apparatus  10  is formed of a length of heavy webbing forming a belt  12 . Loop material  14  is sewn or otherwise attached to the surface of the belt  12  along at least some of the length of the webbing on outer surface, as shown. Rings  16 ,  18  are sewn to the belt  12  with another length of webbing  20 . 
     On the other end of the belt  12  the loop material  14  extends beyond the end of the belt  12 . A length of complementary hook material  22  is attached to the free end of the loop material  14 . By passing the end of the hook material  22  through one of the rings  16  or  18  and then doubling back the hook material  22  onto the loop material  14 , the hooks and loops interlock and the apparatus  10  can be secured around the hips of the user. See  FIG. 2 . A layer of neoprene or some other suitable high-friction material  24  is applied to the inner surface of the belt  12  to increase “grab” with the apparel worn by the user to prevent the apparatus  10  from rotating around the hip during use. 
     Referring back to  FIG. 1 , a pair of D-rings  26 ,  28  are sewn onto the belt  12  in a central position symmetrical with respective ends of the belt  12 . A resistance band  30  is provided and is attached to one or the other of the D-rings  26 ,  28  for use. The resistance band  30  may preferably be an elastic band such as a length of surgical tubing having a predetermined resistance to elongation. Resistance may be obtained by another means, including springs, solid or tubular rubber, plastic bands or other suitable resistance means. 
     The resistance band  30  has a carabiner  32  on one end permitting the resistance band  30  to be releasably attached to the belt  12  by locking into the D-ring  26 , as shown in  FIG. 1 . According to one preferred embodiment of the invention, a carabiner  34  is attached to the other, distal end of the resistance band  30 . A securing strap  36  formed of heavy-duty webbing also includes a carabiner  38  or another heavy-duty ring for attachment to the resistance band  30 . The free, distal end of the securing strap  36  includes a large, heavy-duty foam anchor  40 . By placing the anchor  40  on one side of a door and closing the door, trapping the anchor  40 , the user can then stand away from the door to put initial resistance on the resistance band  30 . The webbing of the securing strap  36  provides a robust anti-wear structure that will resist wear resulting from being tightly trapped between a door and door frame. 
     By rotating the hip closest to the door away from the door, the hip and associated musculature is exercised as desired. See  FIG. 3 . An alternative, not shown, is to provide a resistance band  30  that has a length sufficient to allow the anchor  40  to be attached directly to a distal end of the resistance band  30  by, for example, the carabiner  38 , instead of using the securing strap  36 . 
     The apparatus  10  may be attached to any suitable support, although trapping the resistance band  30  between a door and door frame is ideal, since the range of adjustment is essentially infinite within the height of the door. This permits individuals of differing heights to easily adjust the height as needed. Maximum effectiveness will be achieved with the resistance band extending outwardly from the belt at the approximate height of the belt above floor level, since this position most closely corresponds to the pivoting motion of the hips of the user when swinging a golf club and thus provides training resistance optimized to achieve the desired training results. 
     To exercise the hip in the opposite direction, the carabiner  32  is opened, the resistance band  30  removed from the D-ring  26 , moved to the D-ring  28  and attached in the same manner. See  FIGS. 4 and 5 . 
     As shown in  FIG. 6 , the apparatus  10  may be used by attaching two resistance bands  30  to the respective D-rings  26  and  28 , and then pivoting left and right, either alternately for by pivoting in one direction for a set number of repeats and then in the opposite direction for a set number of repeats. 
     Variations of the design elements described above can be made within the scope of the invention. For example, as shown in  FIG. 7 , a single D-ring  44  is attached to the belt  12  equidistant the opposing ends and permits the user to pivot in both directions without moving the belt  12  from one D-ring to another. 
     Attachment methods other than by use of touch fasteners, for example, a conventional leather, plastic or rubber belt with spaced apart holes adapted to receive the pin of a pin-type buckle, claw buckle, friction buckle and others may be suitable. 
     When training, resistance bands  30  with incrementally increasing levels of resistance may substituted as the exercise strengthens the hips. It has been found that 20 pounds (9 kilograms) may be a suitable weight at the commencement of a training program, with the weight increasing by 10 pound (4.5 kilogram) or 20 pound (9 kilogram) increments up to perhaps 100 pounds (45 kilograms) or greater by attaching multiple resistance bands. 
     An exercise apparatus for strengthening the hips according to the invention has been described with reference to specific embodiments and examples. Various details of the invention may be changed without departing from the scope of the invention. Furthermore, the foregoing description of the preferred embodiments of the invention and best mode for practicing the invention are provided for the purpose of illustration only and not for the purpose of limitation, the invention being defined by the claims.
