PCT No. PCT/GB90/00414 Sec. 371 Date Oct. 3, 1991 Sec. 102(e) Date Oct. 3, 1991 PCT Filed Mar. 19, 1990 PCT Pub. No. WO90/11966 PCT Pub. Date Oct. 18, 1990.An equestrian training aid comprises a chain 10, having spring clips 14, 15 for attachment to the side rings 12, 13 of a horse's bit 11. A plurality of weights 16, in the form of cylindrical bodies each with an axial hole, are carried on the chain, with the chain 10 threaded through the holes of the weights. The number and total mass of the weights are selected to impose a load on the horse's bit and bridle to encourage a desired carriage of the head and promote correct muscular development. The weights will be worn below the horse's jaw behind the chin. The effective length of the chain 16 can be varied by moving one or both of the clips to selected links of the chain, to suit the jaw width of individual horses. The weights may be enclosed in a resilient covering 17 and retained by a resilient disc at each end 18.
