Claim:
1. A collapsing portable apparatus for the training and adjustment of forward, lateral and rotational movement in sports activity which comprises a) a main vertical body which is substantially mandolin shaped having an upper neck and a lower bout, said upper neck is solid and having a generally square horizontal cross section with a plurality of leg arch attaching bolts protruding from a front surface of the upper neck, said lower bout is hollow and generally triangular having a horizontal base and semi-vertical legs of equal length, said lower bout having an axle bore pair perforated through and near to a nexus of the lower bout and the upper neck, said lower bout having a runner bore perforated through and near to an approximate center of the horizontal base; b) a leg arch which is generally arcuate and having a concave surface and a convex surface demountably attached to the upper neck of the apparatus by the joining of a plurality of complimentary bolt keyholes along an approximate center of the convex surface to the leg arch attaching bolts of the upper neck, said leg arch having a removable leg arch pad which is compressible and deformable attached to the concave surface, c) an elongated runner having a generally flat cross section, a curved bow end and a foot plate end, said elongated runner having a support strut attachment bore perforated through and near to an approximate center of the curved bow end, a main vertical body attachment bore perforated through and near to an approximate center of the foot plate end, and a stowage bore perforated through an approximate center of the elongated runner and between the foot plate end and curved bow end, said elongated runner having a foot plate grip zone which is generally rectangular in shape and is attached along a top surface of the foot plate end, d) an extending support strut which is generally cylindrical in shape and is formed by an upper exterior extension pole and a lower interior extension pole which are hollow thereby forming an interior void within each, said lower interior extension pole inserted into the interior void of the upper exterior extension pole thereby allowing variable sliding motion along a single shared central axis relative to and within the interior void of the upper exterior extension pole, said upper exterior extension pole having at least one pair of interior axle bore holes near to an end proximal to the lower bout of the apparatus when assembled and a pair of upper spring clip locking holes near to an end distal to the lower bout of the apparatus when assembled, said lower interior extension pole having a pair of lower spring clip locking holes near to an end proximal to the upper exterior extension pole when assembled and a threaded end cap inserted into an end proximal to the elongated runner when the apparatus is assembled, e) a spring clip with spring clip buttons inserted into the interior void of the lower interior extension pole with spring clip buttons inserted in the lower spring clip locking holes and upper spring clip locking holes thereby joining and locking said extending support strut in an extended configuration when the apparatus is assembled, f) a rivet axle passing through an exterior axle bore of the lower bout of the apparatus and through the interior axle bore holes of the upper exterior extension pole thereby fixing the upper exterior extension pole to the lower bout of the apparatus and allowing rotational and angular movement about the rivet axle and relative to the lower bout, said rivet axle is held in place with a complimentary receiving axle screw, g) a first threaded bolt passing through the support strut attachment bore and into the threaded end cap of the lower interior extension pole thereby attaching the elongated runner to the extending support strut, and h) a second threaded bolt passing through the main vertical body attachment bore of the elongated runner and the runner bore of the lower bout of the apparatus thereby attaching the elongated runner to the main vertical body, said second threaded bolt firmly fixed in position by a complimentary wing nut.
