Groundwork Ideas - no poles!

This week will be a focus on groundwork for me! I was riding on Wednesday and my horse tripped at the canter, was unable to regain her footing, and went totally down with me. She is ok (I gave her some banamine but she seemed fine), but I am still limping around with very painful ribs and a sore ankle. I did get back on and finish my lesson, as my trainer had driven up 1.5hr 😂 I think we're all a little crazy. Anyone have any good groundwork exercises to share that don't require lifting poles or anything too strenuous for me? And yes, I'm going to lunge with lots of transitions to get OFF the dang forehand 🫣🤦🫠
