horse carrying more weight

Question
Hello sir, is there any exercise for racehorses to make them strong enough to carry extra weight than the original weight??

Answer
HI  THE WEIGHTS ARE ASSIGNED FOR THE RACE THAT THE HORSE MUST CARRY. THE CONDITIONS ALSO PLAY A PART ON HOW MUCH WEIGHT THE HORSE HAS TO CARRY IN A RACE.  YOU CAN ALWAYS USE A BIGGER EXERCISE BOY IN THE MORNING TO GALLOP THE HORSES AND THAT WILL BUILD UP THE HORSES MUSSELS AND BREATHING FOR THE RACING. HOPE THAT HELPS YOU  THANKS Ed Hess
