Jockey Training: How to Effectively Change Horse Leads (Without a Whip)

Question
hi sir. can you please teach me how can an apprentice jockey(who cannot a whip in the race) ask his stead to change its lead either from left to right or viceversa?

Answer
hi you usualy teach the horse to change leads by using your heal on command and also use your weight when you switch your body left or right. also you can use the reins on the side of the neck for left or right leads. thanks ED HESS
