Sporting apparatus training aid

A sporting apparatus training aid comprising:

• a unitary and portable body having a proximal end defining an enclosed proximal opening, a distal end opposing the proximal end and defining an enclosed distal opening, a body length separating the proximal and distal ends, an enclosed central wall having an inner surface, an outer surface opposing the inner surface of the central wall, having a plurality of plate-like side fins radially extending outwardly from the outer surface of the central wall, and having a plate-like base fin interposed between each of the plurality of plate-like side fins and having an upper surface and a lower surface opposing the upper surface of the plate-like base fin and disposed at an obtuse angle with respect to the outer surface of the central wall, the plurality of plate-like side fins and the plate-like base fin each having a length and a width greater than a thickness of said plurality of plate-like side fins and plate-like base fin.

In combination with a handheld sporting apparatus having an elongated shaft for gripping by a user and defining a longitudinal axis and a longitudinal plane oriented in a shaft direction and through a centroid on the longitudinal axis, wherein the improvement comprises:

• a unitary body coupled to the sporting apparatus and having a proximal end, a distal end opposing the proximal end, a body length separating the proximal and distal ends, a central wall having an inner surface, an outer surface opposing the inner surface of the central wall, having at least one plate-like, side fin radially extending outwardly from the outer surface of the central wall, with a proximal end, a distal end opposite the proximal end of the at least one plate-like side fin, and opposing side surfaces defining outer side-tin planes oriented in the shaft direction, and having a plate-like base fin with a lower surface and an upper surface opposite the lower surface of the plate-like base fin, the upper surface of the plate-like base fin having the distal end of the at least one plate-like side fin directly coupled thereto and with the upper surface of the plate-like base fin oriented at an obtuse angle with respect to the outer surface of central wall, the at least one plate-like side fin and the plate-like side fin and plate-like base fin.
