         [0004]    Finger strength is an important part of many sports including but not limited to climbing, weightlifting and self defense. Many enthusiasts of these and other sports train on exercise machines in gyms or at home. They also use many forms of training that utilize resistance, whether it be the weight of their own body or the weight of metal plates on a cable pulley exercise machine or a rubber strap, band or tube. Many climbers utilize hangboards that are placed over a doorway in their home, exercise gym or artificial climbing facility. Many artificial climbing facility&#39;s provide climbers with training methods to promote and develop finger strength. 
         [0005]    Although hangboards are useful for climbers to build finger strength they are limited. This is due to fact that they are designed to hang from. When hanging from a hangboard using finger strength, only slow twitch muscles are engaged. When someone is actively climbing, both fast twitch and slow twitch muscle groups are required to hold on and pull oneself upwards. 
         [0006]    Cable pulley machines are useful in developing arm strength. While training on a cable machine the user can develop and strengthen fast twitch muscles. This however does not train finger strength, as the handle is usually a round steel bar that the whole hand can easily wrap around. 
       SUMMARY 
       [0007]    In accordance with one embodiment, the finger strengthening device is comprised of but not limited to a molded shape that has various edges, ledges and cavities with a ring or u bolt connector embedded that can be attached to a resistance training device. 
       Advantages 
       [0008]    The finger strengthening device can be attached to a variety of resistance training devices. In some cases this allows the user to set a chosen amount of weight while training finger strength or pinch strength. This minimizes the risk of injury associated with hangboards or resistance training that utilizes body weight. It also provides a methodical way to incrementally develop finger strength, by conditioning the small tendons and pulleys in the fingers.

       DETAILED DESCRIPTION 
     FIGS.  1 A,  1 B,  1 C and  1 D—First Embodiment 
       [0014]    The finger strengthening device is made up of two main components: the main body and the connector ring. The connector ring component is comprised of a ring with nuts and washers. The main body is shaped so that it is suitable to be gripped by a human hand for the purpose of training grip and finger strength. 
         [0015]    One embodiment of the finger strengthening device is illustrated in  FIGS. 1A ,  1 B,  1 C and  1 D. This embodiment includes a  101  connector ring,  102 , 104 , 105 , 107  four ⅜ nuts,  103 , 106  two ⅜ washers, a  108  vertical pinch area,  109 , 110 , 114 , 115  four finger ledges of varied size, a  111 , 113  medium sized horizontal pinch area, a  112  wide horizontal pinch area and a  117  sloped area with a  116  thumb catch. 
       Operation 
     FIGS.  1 A,  1 B,  1 C,  1 D 
       [0016]    The  101  connector ring can be attached to a resistance device and hung vertically. While in the vertical position the  108  vertical pinch area and the  109 , 110 , 114 , 115  four finger ledges and the  117  sloped area with  116  thumb catch can be utilized while the device is pulled downwards on any type of resistance. 
         [0017]    The  101  connector ring can be attached to a horizontal resistance device. While on a horizontal resistance device the  111 , 113  medium sized pinch and the  112  wide sized pinch can be utilized while pulling in a horizontal direction. 
       Fabrication 
       [0018]    The finger strengthening device can be made through the technique of casting and molding. The main body shape is carved and then a mold is made from the carving. 
         [0019]    The connector ring is embedded in the mold. The martial to be used is then poured into the mold cavity as a liquid where it surrounds the nuts and washers on the connector ring or u-bolt prior to hardening. The connector component cannot be pulled out of the main body once the material hardens.

     FIGS.  3 A,  3 B,  3 C and  3 D—Additional Embodiment 
       [0032]    This embodiment of the finger strengthening device is made up of two main components: the main body and the connector u bolt. The connector u bolt component is comprised of a u bolt with nuts and a plate. This embodiment is spherical in shape and the u-bolt is centered in the sphere. 
       Operation 
     FIGS.  3 A,  3 B,  3 C and  3 D—Additional Embodiment 
       [0033]    The  301  connector u-bolt can be attached to a resistance device and hung vertically or horizontally. While in the vertical position the  308  Sloper grip area can be held while the device is pulled downwards on any type of resistance while the  307  palm stabilizer is against the palm of the users hand. The sphere can also be held like a ball and pulled towards the users body. 
       Alternative Embodiments 
       [0034]    There are many possibility&#39;s for alternative embodiments. Although the descriptions above contain many specificities, these should not be construed as limiting the scope of the embodiments but as merely providing illustrations of some of several embodiments. For example, the molded shape can be square, rectangular, spherical, triangular, ovular or any other shape that creates a grip able part that is beneficial for training grip strength. The connector point can be a ring, a loop, hook, a u shape or any shape that is suitable for connecting to a resistance device. 
         [0035]    Thus the scope of the embodiments should be determined by the appended claims and their legal equivalents, rather than by the examples given.
