I want to start Crossfit to get fit, lose weight. I am a 2-year colon cancer survivor. Chemo caused nerve damage in my feet (neuropathy) to the point that most of my feet are numb causing balance issues. I also have a handful of titanium in my lower back (10+ years ago), a torn ACL in my left knee that never got repaired (Navy doctors!)(20+ years ago). Woefully out of shape & overweight.
Is Crossfit possible for me?
