Will my horse get more graceful at jumping?

I know a horse that was the same and instead of lunging, get on your horse and go over some 18 inch crossrails. Make sure you use pvc piping instead of wooden poles. your horse could get hurt if you use wooden poles. Just keep going over them, he will get better. Raise the jumps after he feels comfortable. I wouldn't keep lunging that teaches him to jump without weight on his back. He will probably react differently then when you are riding him. So it is better to train him under saddle. it depends if he is reliable or not. If you dont feel comfortable, than go back to lunging!
