I already got Missy to rebound off a tree in just a few minutes. I had her rebound me a few times than patted a tree. At first she was just putting her front feet on it than bam she rebound off of it. I had her do it three more times and stopped to end on a good note. And I've been teaching Piper to rebound off me and she's catching on pretty quick. I'm pretty sure though when I get to where I'm standing I'll need something soft to land on... I'm only 113 pounds and Piper is 50 pounds. I already get pushed back from 35 pound Missy.
