2Fly, I?m not an expert so take my advice as opinion rather than fact. The way I understand it, weight training is anaerobic and cardio (elliptical, stairs, etc) is aerobic. You can?t replace one for the other, they both have different values to you. So while you are waiting for your stitches you will miss out on the anaerobic and have to focus solely on the aerobic (although I would think you could do some isolated arm bicep/triceps work). As for the intensity of the aerobic as a replacement for time, it sounds reasonable but I just don?t know for sure.
