I understand your feelings. I had surgery on my knee also because I fell off my bike. This was a very terrible experience for me. Anyway, I started to recover from the surgery. I bought a folding treadmill where I was exercising every day. Anyway, it was hard for me to choose the best one. But, I found an article where are described the
best folding treadmills. After I've read all the details from there I easily made this decision. I exercise a lot on it. The best advantage is the fact that I can fold it and store it.
