DETAILED DESCRIPTION

Both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the features as claimed. As used herein, the terms “comprises,” “comprising,” “having,” including,” or other variations thereof, are intended to cover a non-exclusive inclusion such that a process, method, system, article, or apparatus that comprises a list of elements does not necessarily include only those elements, but may include other elements not expressly listed or inherent to such a process, method, system, article, or apparatus. Further, relative terms, such as, for example, “about,” “substantially,” “generally,” and “approximately” are used to indicate a possible variation of ±10% in a stated value.

A lever arm, also referred to as a “jammer arm,” is a type of exercise equipment configured to be affixed to a beam of an exercise rack and to pivot with respect to the beam. A lever arm is often configured to be translated along, e.g., up or down, a beam of an exercise rack to adjust the height of the lever arm on the beam, based on the type of exercise being performed as well as the height of the user, for example. Embodiments of the present disclosure may allow a user to adjust the height of the lever arm using only one hand, a benefit over other devices that require that the user use both hands for such an adjustment.

FIG. 1 depicts a perspective view of two lever arms 100 affixed to an exercise rack 200. As mentioned above, an exercise rack 200 may include a plurality of beams 202, e.g., one beam 202, two beams 202, three beams 202, four beams 202, etc., and one or more of the beams 202 may include a plurality of holes 204 by which various types of exercise equipment may be affixed to the exercise rack 200, such as the lever arm 100. As depicted in FIG. 1, the lever arm 100 may be configured to be affixed to the beam 202 and to pivot with respect to the beam 202, such that an exercise may be performed through movement of the lever arm 100. A single lever arm 100 or a plurality of lever arms 100 may be affixed to a single exercise rack 200, depending on whether the user intends to exercise one or both arms, for example. As depicted in FIG. 1, in some instances, when two lever arms 100 are affixed to a single exercise rack 200, the two lever arms 100 may be chiral, or mirror images of one another, such that one of the lever arms 100 may be moved with a right hand, and the other lever arm 100 may be moved with a left hand. The lever arms 100 may be moved simultaneously or one at a time. Two lever arms 100 affixed to a single exercise rack 200 may therefore be used to perform one-handed or two-handed exercises.

As depicted in FIG. 1, the lever arm 100 may include an arm 102 having a first end portion 103 and a second end portion 105. The first end portion 103 may include a handle portion 104 configured to be grasped by a hand of a user and a weight attachment portion 106 configured to support at least one weight, e.g., a weight plate, which is removably received by the weight attachment portion 106. However, the handle portion 104 and the weight attachment portion 106 may be positioned at any other appropriate location on the lever arm 100. The weight attachment portion 106 may be a barbell sleeve, or functionally equivalent. The second end portion 105 may include a mount 110 that is rotatably coupled to the arm 102 and configured to releasably couple the lever arm 100 to the beam 202 of the exercise rack 200. For example, in some instances, the mount 110 may be configured to be installed and uninstalled on the beam 202 of the exercise rack 200, or to be moved to different positions or heights along the beam 202. In such an instance, when the mount 110 is installed on the beam 202 of the exercise rack 200, the lever arm 100 may not be released or removed from the beam 202 without uninstalling the mount 110 from the beam 202.

While the mount 110 is installed on the beam 202 of the exercise rack 200, the mount 110 may be put into a slidably coupled state in which the mount 110 may be moved or translated along the beam 202 while the mount 110 is installed on the beam 202, e.g., left or right when the beam 202 extends horizontally relative to a ground surface, or up or down the beam 202 when the beam 202 extends vertically relative to a ground surface. For example, as described in further detail below, when the mount 110 is in the slidably coupled state, the mount 110 may be translated along the beam 202 to reposition the lever arm 100 for performing different exercises, exercising different muscles or muscle groups, or adjusting to a height and/or a position of a user.

As described in greater detail below, while the mount 110 is installed on the beam 202 of the exercise rack 200, the mount 110 may additionally or alternatively be put into a fixed state in which the mount 110 is affixed to the beam 202 and may not be moved or translated along the beam 202. When the mount 110 is in the fixed state, the user may perform various types of exercises by grasping the handle portion 104 and using the handle portion 104 to pivot the lever arm 100 with respect to the beam 202, as depicted in FIG. 1, e.g., with or without a weight coupled to the weight attachment portion 106.

As described in greater detail below, the mount 110 may be configured to be transitioned from the slidably coupled state to the fixed state or from the fixed state to the slidably coupled state, e.g., without being uninstalled from the beam 202, through the use of one or more pins. In some instances, the mount 110 may be transitioned from the fixed state to the slidably coupled state and/or translated along the beam 202, with a single hand of a user. Transitioning the mount 110 from the fixed state to the slidably coupled state may be referred to herein as unfixing the mount 110 from the beam 202. In some instances, the mount 110 may be translated along the beam 202 and/or transitioned from the slidably coupled state to the fixed state with a single hand of a user. Transitioning the mount 110 from the slidably coupled state to the fixed state may be referred to herein as affixing (or reaffixing) the mount 110 to the beam 202.

FIGS. 2A and 2B depict cross-sectional views of the mount 110 of the lever arm 100 installed on the beam 202 of the exercise rack 200. As mentioned above, the mount 110 may be configured to be affixed, unfixed, and/or reaffixed to the beam 202 through the use of one or more pins, as described in further detail below. As mentioned above, in some instances, the mount 110 may be affixed, unfixed, and/or reaffixed to the beam with a single hand of a user.

In the examples depicted in FIGS. 2A and 2B, the mount 110 includes a cuff 120, a mount handle 112 including a mount handlebar 114 and one or more mount handle brackets 113 configured to couple the mount handlebar 114 to the cuff 120, and a mandrel assembly 116 disposed between the cuff 120 and the mount handle 112. FIGS. 2A and 2B depict cross-sectional views of the mount 110 and the beam 202 taken across a plane that is perpendicular to a longitudinal axis of the beam 202. As depicted in FIGS. 2A and 2B, the beam 202 may be a box beam that includes a plurality of lateral sides, e.g., a first lateral side, a second lateral side disposed at a ninety-degree angle to the first lateral side, a third lateral side opposite the first lateral side and disposed at a ninety-degree angle to the second lateral side, and a fourth lateral side opposite the second lateral side and disposed at a ninety-degree angle to both the first lateral side and the third lateral side. One or more lateral sides of the beam 202 may include one or more holes 204. In some instances, two or more lateral sides of the beam 202 may be virtually identical in form.

As depicted in FIGS. 2A and 2B, the cuff 120 may be configured to at least partially surround the beam 202. The cuff 120 may include two or more cuff walls 122 disposed, for example, on two opposite lateral sides of the beam 202, e.g., a first lateral side and a third lateral side of the beam 202 (as described above), and two or more cuff bars 124 disposed between the cuff walls 122 on two other opposite lateral sides of the beam 202, e.g., a second lateral side and a fourth lateral side of the beam 202 (as described above). When the mount 110 is installed on the beam 202, the cuff bars 124 may be configured to make substantially flush contact with the lateral sides of the beam 202, and may be rotatably coupled to the cuff walls 122, such that the cuff bars 124 are configured to be rolled and/or caused to roll when the mount 110 is translated along, e.g., up or down, or left or right, on the beam 202, as described in further detail below. In some instances, the cuff 120 includes two or more cuff pads 126 disposed between the cuff walls 122 and the lateral sides of the beam 202. The cuff pads 126 may be formed of a soft or hard material and may be configured to contact the lateral sides of the beam 202, such that the cuff pads 126 are configured to slide along the lateral sides of the beam when the mount 110 is translated along the beam 202, as described in further detail below. In some instances, the cuff 120 also includes one or more cuff crossbars 128 disposed between the two or more cuff walls 122. As depicted in FIGS. 2A and 2B, the cuff crossbars 128 may be disposed apart from the lateral sides of the beam 202. A cuff crossbar 128 may include one or more holes that may be aligned with and/or similarly sized to one or more holes 204 included in a lateral side of the beam 202. The cuff 120, e.g., the cuff walls 122, the cuff bars 124, the cuff pads 126, and/or cuff crossbars 128, may define an inner cavity. The cuff 120 may be configured to receive the beam 202 within the inner cavity defined by the cuff 120.

As mentioned above, the mount 110 may be configured to be affixed, unfixed, and/or reaffixed to the beam 202 of the exercise rack 200 through the use of one or more pins. In the examples depicted in FIGS. 2A and 2B, the mount 110 includes a removable pin 118 that may be inserted through both a hole 129 included in the cuff crossbar 128 of the cuff 120 (e.g., into the inner cavity defined by the cuff 120) and the hole 204 included in the lateral side of the beam 202, thereby coupling or affixing the mount 110 to the beam 202. In the example depicted by FIG. 2B, the removable pin 118 is withdrawn and removed from both the hole 204 included in the beam 202 and the hole 129 included in the cuff crossbar 128 (e.g., out of the inner cavity defined by the cuff 120), thereby at least partially unfixing the mount 110 from the beam 202.

In some instances, when the removable pin 118 is withdrawn or removed from the beam 202 and/or the cuff 120, the mount 110 may still be affixed to the beam 202 through the use of one or more other pins, such as a mandrel pin 117 (shown in further detail in FIG. 3A) included in the mandrel assembly 116 of the mount 110, as described in further detail below. In some instances, if the removable pin 118 is withdrawn or removed from the beam 202 and/or the cuff 120, and the mount 110 is not affixed to the beam 202 through the use of one or more other pins, such as the mandrel pin 117, the mount 110 is fully unfixed from the beam 202 and thereby transitioned from the fixed state to the slidably coupled state, in which the mount 110 may be translated along the beam 202, as described in further detail below. In some instances, the removable pin 118 may be withdrawn or removed from the beam 202 and/or the cuff 120 with a single hand of a user.

FIGS. 3A and 3B depict cross-sectional views of the mount 110 of the lever arm 100 installed on the beam 202 of the exercise rack 200, taken across a plane that is parallel to a longitudinal axis of the beam 202. In the examples depicted in FIGS. 3A and 3B, the mount 110 includes the cuff 120, the mount handle 112 including the mount handlebar 114 and one or more mount handle brackets 113 configured to couple the mount handlebar 114 to the cuff 120, and the mandrel assembly 116 disposed between the cuff 120 and the mount handle 112. As depicted in FIGS. 3A and 3B, the mount handlebar 114 may be coupled to the mount handle brackets 113 via one or more fasteners 111, such as screw or bolts, for example.

As mentioned above, in some instances, the mount 110 of the lever arm 100 may be configured to be affixed, unfixed, and/or reaffixed to the beam 202 of the exercise rack 200, and/or translated along the beam 202 of the exercise rack 200, with a single hand of a user. In the example depicted in FIGS. 3A and 3B, the mandrel assembly 116 may include a mandrel bar 115 and the mandrel pin 117 coupled together to form a T-shaped mandrel. The mandrel assembly 116 may be operatively coupled to both the mount handle 112 and the cuff 120 such that the mount handle 112, the mandrel assembly 116, and the cuff 120 may be used to affix, unfix, and/or reaffix the mount to the beam 202, and/or to translate the mount 110 along the beam 202, with a single hand of a user. For example, as depicted in FIG. 3A, the cuff 120 may include a cuff chamber 123 configured to receive the mandrel pin 117, and a spring 125 (or any other suitable resilient member) may be disposed between a head 127 of the mandrel pin 117 and a wall of the cuff chamber 123, such that the spring 125 may be configured to bias the mandrel pin 117 toward a first position in which the mandrel pin 117 is inserted through a hole 141 in the cuff wall 122 and a hole 204 included in a lateral side of the beam 202, thereby affixing the cuff 120, and, by extension, the mount 110 and the lever arm 100, to the beam 202. A central axis of the hole 141 in the cuff wall 122 may be perpendicular to a central axis of the hole 129 included in the cuff crossbar 128.

In this example, as depicted in FIGS. 3A and 3B, each mount handle bracket 113 includes a slot 119 that extends longitudinally along its respective mount handle bracket 113 and is configured to translatably receive an end of the mandrel bar 115, such that the mandrel bar 115 may be pulled toward the mount handlebar 114 to move the mandrel pin 117 away from the first position and toward a second position in which the mandrel pin 117 is withdrawn from the hole 204 included in the lateral side of the beam 202, thereby at least partially unfixing the mount 110 from the beam 202.

In some instances, the mandrel bar 115 may be pulled toward the mount handlebar 114, thereby moving the mandrel pin 117 away from the first position and toward the second position and at least partially unfixing the mount 110 from the beam 202, by squeezing the mandrel bar 115 and the mount handlebar 114 together with a single hand of a user. In some instances, when the mandrel pin 117 is withdrawn from the beam 202, the mount 110 may still be affixed to the beam 202 through the use of one or more other pins, such as the removable pin 118, as described above. In some instances, if the mandrel pin 117 is withdrawn from the beam 202, and the mount 110 is not affixed to the beam 202 through the use of one or more other pins, such as the removable pin 118, the mount 110 is fully unfixed from the beam 202, thereby transitioning the mount 110 from the fixed state to the slidably coupled state, in which the mount 110 may be translated along the beam 202, as described in further detail below. For example, in some instances, a user of the lever arm 100 may partially unfix the mount 110 from the beam 202 by withdrawing the removable pin 118 from the beam 202 and the cuff 120, as described above, with a single hand. The user may then squeeze the mandrel bar 115 and the mount handlebar 114 together with a single hand, thereby compressing the spring 125, withdrawing the mandrel pin 117 from the hole 204 in the beam 202, and fully unfixing the mount 110 from the beam 202. Then, with the single hand being used to squeeze the mandrel bar 115 and the mount handlebar 114 together, the user may use the mount handle 112 to translate the cuff 120 up or down the beam 202. After translating the cuff 120 up or down the beam 202, the user may release the mandrel bar 115, such that the spring 125 expands and causes the mandrel pin 117 to be inserted into another hole 204 in the beam 202, thereby at least partially reaffixing the mount 110 to the beam 202.

FIG. 4 depicts a flowchart of a method 300 for operating the mount 110 of the lever arm 100 installed on the beam 202 of the exercise rack 200. As described above, the beam 202 may include a plurality of lateral sides, and the mount 110 may include the cuff 120 configured to at least partially surround the beam 202 and to be translated along the beam 202, the mount handle 112 coupled to the cuff 120 and including the mount handlebar 114 spaced apart from the cuff 120, and the mandrel assembly 116 including the mandrel bar 115 disposed between the mount handle 112 and the cuff 120, and the mandrel pin 117 configured to be inserted through the beam 202.

As depicted in FIG. 4, the method 300 may include a step 302, in which a user of the lever arm 100 squeezes the mandrel bar 115 and the mount handlebar 114 together to move the mandrel pin 117 away from a first position in which the mandrel pin 117 is inserted through a first one of the holes 204 in the beam 202 and the cuff 120 of the mount 110 is affixed to the beam 202, toward a second position in which the mandrel pin 117 is withdrawn from the first one of the holes 204 in the beam 202, such that the cuff 120 may be translated along the beam 202. For example, as described above, the mandrel bar 115 may be at least partially and removably disposed within one or more slots 119 included in one or more mount handle brackets 113, the mandrel pin 117 may be disposed within the cuff chamber 123 of the cuff 120, and the spring 125 may be disposed between the head of the mandrel pin 117 and the wall of the cuff chamber 123. The spring 125 may be configured to bias the mandrel pin 117 toward the first position. In this example, the user squeezes the mandrel bar 115 and the mount handlebar 114 together with a single hand, thereby withdrawing the mandrel pin 117 from the first one of the holes 204 in the beam 202 and compressing the spring 125.

As depicted in FIG. 4, after the user squeezes the mandrel bar 115 and the mount handlebar 114 together to move the mandrel pin 117 away from the first position and toward the second position, the method 300 may continue with a step 304, in which the user translates the cuff 120 along the beam 202 using the mount handle 112. For example, with the mandrel bar 115 and the mount handlebar 114 squeezed together in a single hand, the user may use the mount handlebar 114 coupled to the cuff 120 by the mount handle brackets 113 to move the cuff 120 along the beam 202 with the single hand.

As depicted in FIG. 4, after the user translates the cuff 120 along the beam 202 using the mount handle 112, method 300 may continue with a step 306, in which the user releases the mandrel bar 115 to move the mandrel pin 117, or to allow the mandrel pin 117 to be moved, away from the second position and toward a third position in which the mandrel pin 117 is inserted through a second one of the holes 204 in the beam 202, such that the cuff 120 is reaffixed to the beam 202 at a different position along the beam 202. The first position and the third position may be virtually identical except for the respective hole 204 of the beam 202 into which the mandrel pin 117 is inserted. For example, with the mandrel bar 115 and the mount handlebar 114 squeezed together in a single hand, the user may release the mandrel bar 115, e.g., while maintaining their hold on the mount handlebar 114, thereby allowing the spring 125 to expand and cause the mandrel pin 117 to move back toward the beam 202 and into the second one of the holes 204 in the beam 202, thereby reaffixing the cuff 120, and, by extension, the mount 110 and the lever arm 100, to the beam 202.

In some instances, before squeezing the mandrel bar 115 and the mount handlebar 114 together to move the mandrel pin 117 away from the first position and toward the second position, the user removes the removable pin 118 from a third one of the holes 204 in the beam 202, thereby partially unfixing the mount 110 from the beam 202. In such an instance, squeezing the mandrel bar 115 and the mount handlebar 114 together in step 302 may fully unfix the mount 110 from the beam 202. Similarly, in some instances, after releasing the mandrel bar 115 to move the mandrel pin 117, or to allow the mandrel pin 117 to be moved, away from the second position and toward the third position, the user inserts the removable pin 118 into a fourth one of the holes 204 in the beam 202. In such an instance, inserting the removable pin 118 into the fourth one of the holes 204 in the beam 202 may prevent the mount 110 from being fully unfixed, e.g., inadvertently, from the beam 202 through the use of the mandrel assembly 116. In some instances, the first one of the holes 204 and the second one of the holes 204 are disposed on a first lateral side of the beam 202, and the third one of the holes 204 and the fourth one of the holes 204 are disposed on a second lateral side of the beam 202 that is adjacent to the first lateral side.

FIGS. 5A and 5B depict the first end portion 103 of the of the arm 102 of the lever arm 100. As mentioned above, the first end portion 103 may include a handle portion 104 configured to be grasped by a hand of a user and a weight attachment portion 106 configured to support at least one weight. In some instances, the first end portion 103 may be translated along the arm 102, such as to reposition the handle portion 104 and/or the weight attachment portion 106 for performing different exercises, exercising different muscles or muscle groups, or adjusting to a height and/or position of a user. For example, in some instances, the first end portion 103 may be transitioned between a fixed state, in which the first end portion 103 is affixed to the arm 102 and may not be moved or translated along the arm 102, and a slidably coupled state, in which the first end portion 103 is unfixed from the arm 102 and may be moved or translated along the arm 102.

In some instances, as depicted in FIGS. 5A and 5B, the arm 102 may be formed of a beam 109, e.g., a box beam, including a plurality of lateral sides, e.g., a first lateral side, a second lateral side disposed at a ninety-degree angle to the first lateral side, a third lateral side opposite the first lateral side and disposed at a ninety-degree angle to the second lateral side, and a fourth lateral side opposite the second lateral side and disposed at a ninety-degree angle to both the first lateral side and the third lateral side. One or more lateral sides of the beam 109 of the arm 102 may include one or more holes 138. In some instances, two or more lateral sides of the beam 109 of the arm 102 may be virtually identical in form.

The handle portion 104 may be configured to be affixed, unfixed, and/or reaffixed to the arm 102, e.g., to the beam 109 of the arm 102, through the use of one or more pins. For example, in some instances, as depicted in FIGS. 5A and 5B, the handle portion 104 of the first end portion 103 may include at least one handlebar 131 transverse to the beam 109 of the arm 102 and at least one removable handle pin 132. The at least one removable handle pin 132 may be configured to be inserted into at least a first one of the one or more holes 138 included the beam 109 of the arm 102 and into the at least one handlebar 131 to releasably couple the handle portion 104 to the beam 109 of the arm 102. For example, the at least one handlebar 131 may include a hollow portion 136 configured to receive the at least one removable handle pin 132. In some instances, the at least one removable handle pin 132 is configured to be magnetically coupled to the at least one handlebar 131. However, the at least one removable handle pin 132 may be coupled to the at least one handlebar 131 in any other appropriate way, e.g., the at least one removable handle pin 132 may be screwed into the at least one handlebar 131.

In some instances, as depicted in FIGS. 5A and 5B, the handle portion 104 may include a first handlebar 131 transverse to the beam 109 of the arm 102, a second handlebar 131 transverse to the beam 109 of the arm 102, a first removable handle pin 132 configured to be inserted into a first one of the one or more holes 138 of the beam 109 of the arm 102 and into the first handlebar 131, and a second removable handle pin 132 configured to be inserted into a second one of the one or more holes 138 of the beam 109 of the arm 102 and into the second handlebar 131. The first handlebar 131 and the second handlebar 131 may be coupled at least in part by at least one additional handlebar 133 that is transverse to both the first handlebar 131 and the second handlebar 131. In some instances, the first handlebar 131 and the second handlebar 131 are substantially parallel to one another and/or substantially perpendicular to the beam 109 of the arm 102. In some instances, as mentioned above, the weight attachment portion 106 includes a barbell sleeve, and both the first handlebar 131 and the second handlebar 131 may be substantially parallel to the barbell sleeve of the weight attachment portion 106.

In some instances, as depicted in FIGS. 5A and 5B, the first end portion 103 may include a handle cuff 134 configured to at least partially surround the beam 109 of the arm 102 and to be translated along the beam 109 of the arm 102. The handle cuff 134 may include two or more handle cuff walls 143 disposed, for example, on two opposite lateral sides of the beam 109 of the arm 102, e.g., a first lateral side and a third lateral side of the beam 109 of the arm 102 (as described above). The handle cuff 134 may include one or more holes 139 that may be aligned with and/or similarly sized to one or more holes 138 of the beam 109 of the arm 102. The handle portion 104 and/or the weight attachment portion 106 of the first end portion 103 may be coupled to the handle cuff 134. In such an instance, the at least one removable handle pin 132 may be configured to be inserted through at least a first one of the one or more holes 138 of the beam 109 of the arm 102, at least a first one of the one or more holes 139 of the handle cuff 134, and the at least one handlebar 131 to releasably couple the handle portion 104 to the beam 109 of the arm 102.

For example, the beam 109 of the arm 102 may include four lateral sides (as described above), the handle cuff 134 may include four lateral sides (as described above) corresponding to the four lateral sides of the beam 109 of the arm 102, and the four lateral sides of the handle cuff 134 may define an inner cavity 135 configured to receive the four lateral sides of the beam 109 of the arm 102. In this example, the handle portion 104 includes a first handlebar 131, a second handlebar 131 parallel to the first handlebar 131, a first removable handle pin 132, and a second removable handle pin 132. As depicted in FIG. 5B, along a first direction aligned with a longitudinal axis of the first handlebar 131, the first removable handle pin 132 may be configured to be inserted in order through a first hole 139 included in first lateral side of the handle cuff 134, through a first hole 138 included in a first lateral side of the beam 109 of the arm 102, through a second hole 138 included in a third lateral side of the beam 109 of the arm 102 opposite the first lateral side of the beam 109 of the arm 102 (as described above), through a second hole 139 included in a third lateral side of the handle cuff 134 opposite the first lateral side of the handle cuff 134 (as described above), and finally into a hollow portion 136 of the first handlebar 131. Along a second direction aligned with a longitudinal axis of the second handlebar 131, the second removable handle pin 132 may be configured to be inserted in order through a third hole 139 included in the first lateral side of the handle cuff 134, through a third hole 138 included in the first lateral side of the beam 109 of the arm 102, through a fourth hole 138 included in the third lateral side of the beam 109 of the arm 102, through a fourth hole 139 included in the third lateral side of the handle cuff 134, and finally into a hollow portion 136 of the second handlebar 131.

In the example described above, when one or more of the first removable handle pin 132 and the second removable handle pin 132 are inserted into the handle cuff 134, the beam 109 of the arm 102, and the first handlebar 131 and the second handlebar 131, respectively, the first end portion 103 is thereby transitioned into the fixed state, in which the first end portion 103 is fixed to the arm 102 may not be moved or translated along the arm 102. When both the first removable handle pin 132 and the second removable handle pin 132 are withdrawn from the first handlebar 131, the second handlebar 131, the handle cuff 134, and the beam 109 of the arm 102, the first end portion 103 is thereby transitioned into the slidably coupled state, in which the first end portion 103 is unfixed from the arm 102 and may be moved or translated along the arm 102. For example, in such an instance, when the first removable handle pin 132 and the second removable handle pin 132 are withdrawn from the first handlebar 131, the second handlebar 131, the handle cuff 134, and the beam 109 of the arm 102, the first end portion 103 is fully unfixed from the beam 109 of the arm 102, and a user of the lever arm 100 may use either or both of the first handlebar 131 and the second handlebar 131 of the handle portion 104 and/or the weight attachment portion 106 to translate the handle cuff 134, and, by extension, the first end portion 103, to a different position along the arm 102. After translating the first end portion 103 to a different position along the arm 102, the user may reinsert the first removable handle pin 132 and/or the second removable handle pin 132 through different holes 138 and 139 of the beam 109 of the arm 102 and the handle cuff 134, respectively (as described above), and into the first handlebar 131 and the second handle bar 131, respectively (as described above), thereby at least partially reaffixing the first end portion 103 to the arm 102.

As mentioned above, the first end portion 103 may be configured to be affixed, unfixed, and/or reaffixed to the arm 102, e.g., to the beam 109 of the arm 102, through the use of one or pins. In the examples depicted in FIGS. 5A and 5B, the first end portion 103 includes a removable pin 137 that may be inserted through both at least one hole 139 in the handle cuff 134 (e.g., into the inner cavity 135 defined the handle cuff 134) and/or at least one hole 138 in the beam 109 of the arm 102. As depicted in FIGS. 5A and 5B, when both a removable handle pin 132 is inserted into a handlebar 131 of the handle portion 104, and when the removable pin 137 is inserted into the handle cuff 134, the removable pin 137 may be positioned just below removable handle pin 132, thereby at least partially preventing the first end portion 103 from being translated along the arm 102, e.g., the beam 109 of the arm 102, in at least one direction, e.g., downward. As such, the removable pin 137 may be used to at least partially affix (or reaffix) the first end portion 103 to the arm 102.
