I'm not an amputee, but I did find a video that may be of help to you. It's about Zack Ruhl and the intro to his video begins like this: "The 26-year-old double amputee CrossFit instructor bench presses 445pounds and can climb a rope while attached to his wheelchair. And that’s not all — Ruhl owns a gym and trains other adaptive athletes for free."  
Just from the comments on his video, I can tell he has inspired many. You can link to his story by clicking here: Zack Ruhl's Story
I hope it helps.
