Groundwork ideas for building trust with new horse
I'm interested in doing some groundwork with my horse.
I've only had him a little over two months. A few days ago, I came off him after a bucking fit and I injured my ankle pretty badly, so I won't be riding for a little while! I'd like to get to know him better on the ground and do some things with him while I heal. He's an 11 y/o TB with a healthy respect for people, but he won't hesitate to check out your hands if he thinks you've got apples hidden in them! He's quite good to lunge, too, he doesn't really need a lunge whip.
Any suggestions for things I could work on? I don't have access to a round pen. I did try to join up with him a few times, I got him to the licking and chewing phase, but whenever I went passive, he would keep going around the circle. So I pushed him out again, but after a while, we both got tired, he would try to rest in the corners of the makeshift pen, and we both gave up. So it didn't really work. :/ No hate please, I'm a new owner and still figuring out what I can do with my horse! I'm open to ideas for light stuff I can do to get to know him better while I'm unable to ride.
