The sports training aid includes an arm attachment (2) having a metal plate in a secure fastened plate pocket (3A) of a sleeve (4) with straps (5A, 5B, 5C, 5D). A pair of shafts (6A and 6B) extend from the plate (3). Attached to the ends of the shafts (6A, 6B) is an arm rest in the form of generally rectangular plate (7) which is substantially C-shaped in cross section. A strut (8) between the shafts (6A, 6B) gives rigidity to the structure. The arm attachment device and arm rest (7) taper towards each other, e.g. at an angle of about 30 degrees. The arm attachment device, arm rest and shafts (6A, 6B) and strut (8) lie generally in the same plane. The sports training aid may include an extendible shaft or shafts and the sports training aid may have means to adjust the angle of the arm attachment relative to the arm rest.
