I have a lovely but slightly lazy warmblood. When I am schooling her I am finding she really hollows especially through transitions. I am trying to ride her forward & make her work her work from behind. She has a lovely soft mouth & I don't want to be hauling at her mouth. The only way I can get her long & low is if my hands are really low and too far apart. I don't want to ruin her with my rubbish riding. Just looking for some tips, advice to get her nice & forward and not go round looking like a big orange giraffe.
