Ok.. so I have been riding at this stable for about a year now and have been practicing sholder ins for about 3 months!!! I ride a regular lesson horse that is widly used. But I have also ridden this other horse that is better for me in size and ability. He is also a dressage horse. Better for practicing sholder ins? I know he does it when I tell him to but by myself I don't know. My trainer usually tells me if he is or isnt doing it. Is there a way that I can sit or anything that will help me know that he is doing the sholder in??
