Claim 1
Independent Claim
153 words
A sports training apparatus which comprises: (a) a support base comprising a body having movable weights positionable in one or more vertical cavities formed by an upper wall in said body wherein (i) said upper wall of said cavities have a horizontal groove extending partially around said upper wall and have a vertical slot connecting said groove and the top surface of said support base, and (ii) said weights having a protruding tap, shaped to pass down said slot and rotatable into said groove, (b) an extendable pole vertically attached to said support base and having an arm member perpendicularly attached to said pole and of a length to extend beyond said support base, (c) a ball attached by a flexible line to said arm member, and (d) a player positioning means adjustabley attached to said support base such that a portion thereof will protrude at a pre-determined distance from said support base.
