A user engagement element is coupled to the first elongate rod. A second elongate rod is longitudinally aligned with respect to the first elongate rod. A second engagement element is coupled the second elongate rod. A first stopper is movably coupled to the second elongate rod and a second stopper is movably coupled to the second elongate rod. A portion of the first elongate rod is slideable between the first stopper and the second stopper. ## Claims ### Claim 1 A sports training device, comprising: a first elongate rod; a user engagement element coupled to the first elongate rod, the user engagement element being sized and configured to be releasably disposed around a first portion of a user's body; a second elongate rod movably coupled to and longitudinally aligned with the first elongate rod; a second engagement element coupled to the second elongate rod, the second engagement element being sized and configured to releasably couple to at least one from the group consisting of a second portion of the user's body different than the first portion and a sports device; a first stopper movably coupled to the second elongate rod; a second stopper movably coupled to the second elongate rod; and a portion of the first elongate rod being slideable during use between the first stopper and the second stopper. ### Claim 2 (depends on 1) The sports training device of claim 1, wherein the second engagement element includes a clamp configured to engage a handle of a sports device. ### Claim 3 (depends on 1) The sports training device of claim 1, wherein the first elongate rod includes a first end and a second end, and wherein the first elongate rod includes a coupling element included at the first end, and wherein the user engagement element is coupled to the second end. ### Claim 4 (depends on 3) The sports training device of claim 3, wherein the coupling element defines a passage, and wherein a portion of the second elongate rod is slideably received within the passage. ### Claim 5 (depends on 1) The sports training device of claim 1, wherein the user engagement element includes a strap sized to wrap around a human arm. ### Claim 6 (depends on 5) The sports training device of claim 5, wherein the second engagement element includes a strap sized to wrap around a human wrist. ### Claim 7 (depends on 1) The sports training device of claim 1, wherein the user engagement element includes a strap sized to wrap around a human waist. ### Claim 8 (depends on 1) The sports training device of claim 1, wherein the user engagement element is rotatably coupled to the first elongate rod. ### Claim 9 (depends on 1) The sports training device of claim 1, wherein the second engagement element is pivotally coupled to the second elongate rod. ### Claim 10 (depends on 1) The sports training device of claim 1, wherein the second elongate rod defines a curved section proximate the second engagement element configured to align a midpoint of second engagement element with a midpoint of the user engagement element. ### Claim 11 (depends on 1) The sports training device of claim 1, wherein the second rod is arranged in a side-by-side relationship with the first elongate rod. ### Claim 12 A sports training device, comprising: a first elongate rod having a first length, a first end, and a second end; a coupling element disposed at the first end, the coupling element having a second length less than the first length, the coupling element further defining a passage there through; a user engagement element coupled to the second end, the user engagement element being configured to releasably couple to an arm of a user's; a second elongate rod slideably received within the passage; a second engagement element being coupled to the second elongate rod, the second engagement element being configured to releasably couple to a sports device; a first collar and a second collar movably coupled to the second elongate rod; and the coupling element being slideable between the first collar and the second collar; a portion of the first elongate rod being slideable during use between the first collar and the second collar. ### Claim 13 (depends on 12) The sports training device of claim 12, wherein the second engagement element includes a clamp configured to engage a handle of the sports device. ### Claim 14 (depends on 12) The sports training device of claim 12, wherein the user engagement element is rotatably coupled to the first elongate rod. ### Claim 15 (depends on 12) The sports training device of claim 12, wherein the second engagement element is pivotally coupled to the second elongate rod. ### Claim 16 (depends on 12) The sports training device of claim 12, wherein the user engagement element includes a strap sized to wrap around at least one of a human arm and a human wrist the arm. ### Claim 17 (depends on 12) The sports training device of claim 12, wherein the second elongate rod has a third length, and wherein the first length is larger than the third length. ### Claim 18 A sports training device, comprising: a first elongate rod having a first length, a first end, and a second end; a coupling element disposed at the first end, the coupling element having a second length less than the first length, the coupling element further defining a passage there through; a first user engagement element rotatably coupled to the second end, the first user engagement element being sized and configured to releasably couple to a wrist and hand of a user's; a second elongate rod slideably received within the passage; a second user engagement element being pivotally and rotatably coupled to the second elongate rod, the second user engagement element including a strap and a plate and being sized to releasably coupled to a portion of a user's upper arm; a first collar and a second collar movably coupled to the second elongate rod; and the coupling element being slideable between the first collar and the second collar; a portion of the first elongate rod being slideable during use between the first collar and the second collar.
