## Background
BACKGROUND OF THE DISCLOSURE
Field of the Disclosure
The disclosure relates to exercise devices and more particularly pertains to a new exercise device for strengthening wrists, forearms and chest of a user through manipulation of a compact easy to use apparatus.
SUMMARY OF THE DISCLOSURE
An embodiment of the disclosure meets the needs presented above by generally comprising a first handle and a shaft extending from the first handle.

There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.

DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 7 thereof, a new exercise device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 7, the exercise apparatus 10 generally comprises a first handle 12 having a flared portion 14 extending outwardly from a grip area 16 of the first handle 12 towards a first end 18 of the first handle 12. Thus, the first handle 12 is configured for preventing slipping of a user's hand 20 off of the first end 18 of the first handle 12 during use. A shaft 22 extends from the first end 18 of the first handle 12. A protrusion 24 extends from the shaft 22. The protrusion 24 is positioned proximate a distal end 26 of the shaft 22 relative to the first handle 12. A second handle 28 has a cylindrical inner wall 30 extending into the second handle 28 from a first end 32 of the second handle 28. The inner wall 30 forms a chamber 34 extending into the second handle 28 from an opening 36 in the first end 32 of the second handle 28. The chamber 34 is shaped to receive the shaft 22. The second handle 28 has a flared portion 38 extending outwardly from a grip area 40 of the second handle 28 towards the first end 32 of the second handle 28. Thus, the second handle 28 is configured for preventing slipping of a user's hand 20 off of the first end 32 of the second handle 28 during use.
A biasing member 42 is positioned between the first handle 12 and the second handle 28. The biasing member 42 is compressed to urge the first handle 12 away from the second handle 28 when the shaft 22 is inserted into the chamber 34. The biasing member 42 is one of a plurality of interchangeable biasing members 42 as shown in FIG. 5. Each biasing member 42 has a unique resistance to compression. Thus, the amount of strength required to fully insert the shaft 22 into the chamber 34 is variable by selection of the desired biasing member 42.
An annular track 44 is positioned in the first end 18 of the first handle 12. The annular track 44 in the first handle 12 extends around the shaft 22. The annular track 44 in the first handle 12 is sized to receive a first end 46 of the biasing member 42. An annular track 48 is positioned in the first end 32 of the second handle 28. The annular track 48 in the second handle 28 extends around the opening 36 in the first end 32 of the second handle 28. The annular track 48 in the second handle 28 is sized to receive a second end 50 of the biasing member 42.
A channel 52 is positioned in the chamber 34 and extends into the inner wall 30 of the second handle 28. The protrusion 24 is positioned in the channel 52 when the shaft 22 is inserted into the chamber 34. The channel 52 has a longitudinal portion 54 relative to the second handle 28 and a transverse portion 56 relative to the second handle 28. The channel 52 may also have a medial portion 58 extending between the longitudinal portion 54 of the channel 52 and the transverse portion 56 of the channel 52.
A mounting block 60 may be provided having a cylindrical inner wall 62 extending into the mounting block 60 from a first end 64 of the mounting block 60. The inner wall 62 forms a cavity 66 extending into the mounting block 60 from an aperture 68 in the first end 64 of the mounting block 60. The cavity 66 is shaped to receive the shaft 22. An annular trough 70 may be located in the first end 64 of the mounting block 60.
The annular trough 70 in the mounting block 60 extends around the aperture 68 in the first end 64 of the mounting block 60. The annular trough 70 in the mounting block 60 is sized to receive the second end 50 of the biasing member 42. A connection tab 72 extends from the mounting block 60. The connection tab 72 has a hole 74. Thus, the mounting block 60 is configured for being coupled to a support surface 76 by insertion of a connector 78 through the hole 74.
A groove 80 is positioned in the cavity 66 and extends into the inner wall 62 of the mounting block 60. The protrusion 24 is positioned in the groove 80 when the shaft 22 is inserted into the cavity 66. The groove 80 has a longitudinal portion 82 relative to the mounting block 60 and a transverse portion 84 relative to the mounting block 60. The groove 80 has a medial portion 86 extending between the longitudinal portion 82 of the groove 80 and the transverse portion 84 of the groove 80.
In use, the desired biasing member 42 is selected and positioned between the first handle 12 and the second handle 28. The first handle 12 and the second handle 28 are grasped and the shaft 22 is inserted into the chamber 34 through the opening 36. The user compresses the first handle 12 towards the second handle 28 working the muscles in the arms, back and chest. The first handle 12 and second handle 28 are twisted relative to each other as the protrusion 24 is moved through the medial portion 58 and transverse portion 56 of the channel 52. The first handle 12 may be used similarly with the mounting block 60 instead of the second handle 28 to work only one side of the body.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure.
