<img alt="" class="inlineimg" src="/images/smilies/sad.gif" style="border:0px solid;" title=""> So, in preparation for my latest marathon (supposed to be today), I decided to do a short run on Sunday morning just to improve my flexibility and keep my "edge" up. Beautiful day, wonderful run, felt fast and good. Until I was .25 miles from home and suddenly found myself lying on the asphalt in horrible pain. I don't know what happened, but I heard a jingling noise as I went down and sort of came to lying on a random metal hoop (think the top hoop of a tomato cage - that's what it looked like), so I assume I tripped. All day Sunday I limp around the house, my left knee swollen and the cap sticking out like a goose egg. So yesterday morning I went to the doctor and though nothing is broken, a torn ACL looks likely. I'm on crutches until next Wednesday at least and am forbidden to do anything that would use my leg or put pressure on it. No running (obviously), no cycling, not even swimming. I need to do something or I'm going to go nuts. I don't belong to a gym (though I might join one briefly if I have to). I do have a pilates ball and access to workout vids at the local library. Can anyone recommend some kind of killer upper-body-only exercise? I'll definitely do some strength training but is there some kind of aerobic upper body exercise? I hope to be able to get into swimming again next Wednesday. But going from 60 mpw to 0 in one fell swoop makes Cassiel go crazy.
