Collection without bit?

Try a leather bitless with a chain over and under the nose to act as an outer bit. Just don't pull the reins that much. To get him collected. This is what i learned, keep your rib cage down, sit down on your but, shoulders back, and use your knees as if you were lifting the saddle up with you. Keep your thighs squeezing down on the saddle as well use these aids and you horse is going to get collected for sure. To check if your using the aids right apply them one by one, watch his ears. Hope that helped
