Systems and methods for golf swing training

1. A golf swing training device, comprising:

a first elongate member and a second elongate member each coupled at and extending orthogonally from a junction, wherein the second elongate member is shorter than the first elongate member, and wherein a distal end of the second elongate member is sharply tapered to a point, wherein the junction includes a frangibility feature, wherein in response to applying an impact force to the first elongate member, the first elongate member is separated from the junction with the second elongate member by shearing at the frangibility feature.

2. The golf swing training device of claim 1 , wherein the ratio of the length of the first elongate member to the second elongate member is about 1:1.2.

3. The golf swing training device of claim 1 , wherein an interior angle defined by an intersection between the center lines of first elongate member and the second elongate member is between 85° and 95°.

4. The golf swing training device of claim 1 , further comprising a flanged portion projecting radially from the second elongate member.

5. The golf swing training device of claim 4 , wherein the flanged portion includes a frustoconical portion.

6. The golf swing training device of claim 4 , wherein the flanged portion is removable.

7. The golf swing training device of claim 1 , wherein the second elongate member comprises a detent.

8. The golf swing training device of claim 1 , wherein the junction includes a web portion extending between the first elongate member and the second elongate member.

9. The golf swing training device of claim 1 , wherein the frangibility feature includes at least one of a cutout portion or a shear line.

10. A method of providing golf swing feedback, comprising:

aligning a first elongate member of a swing training device above a golf ball;

selecting a desired height of the first elongate member above the golf ball;

applying an insertion force to a second elongate member of the swing training device and, in response, inserting a distal end of the second elongate member below a substrate;

removing the insertion force in response to at least one of a tactile feedback, a visual feedback, or contacting a flanged portion with the substrate; and

applying an impact force to the first elongate member and, in response to the impact force, shearing the first elongate member from a junction between the first elongate member and the second elongate member.
