A conundrum

I'm confusing my physical therapist. He can't quite figure out the exact problem and how to make it better. I have a new exercise. This one has me bending backward. Amazingly, it seems to help. I can still do the press ups. He was pressing on my spine and had me doing them. I'm going to be an arm wrestling champ by the time I'm done. I can't bend down, but I can bend backward and have super strong arms!
