from excersize that is....well..I should also say that I can feel the soreness coming on as I type. a week before Christmas, I had full ACL reconstructive surgery using part of my patelar tendon as a donar.. PT is going well so far. Prior to my injury, cycling was a big hobby of mine, so getting back on the bike is a big deal for me. I am into week 12 and today decided to step up my cycling on the stationary recumbant. 45minutes on level 7. I am damn proud of myself. Just thought I'd share that with you. ..oh..and today I got permission from my orthopedic surgeon to actually ride my bike (on controlled surface streets for now)!!! woohoo!!!
