Thanks I will try taking away the stirrups and gripping with my legs. :)
Grip with your legs! I also recommend not using stirrups at first, try to go as slow as possible but still maintaining a trot
Train, train and train! Torture yourself again and again😄
Try not to sit on your bum, because that will make it more bouncy. Don't hold with your knees; instead, hold with your calves. That will give you more stabilization. And always make sure the horse isn't going too fast!
