A type of horse that is of a medium build. Most riding and sport horse breeds are Warmbloods. There are over 100 breeds worldwide that can be described as a Warmblood type. The expression 'Warmbloods' originates from the Anglo-French usage of this term to differentiate the light riding horse breeds from the even lighter 'Hotbloods' (Thoroughbreds and Arabs) and the heavier 'Coldbloods' (heavy draught breeds).
