Ok, so I started running again after about 10 years of not doing anything. I have been following a couch to 10K program and it is working pretty darn good. The problem is, I am on week 3 about to move into week 4 and I tore my calf muscle. Granted it's a grade 2 and it will heal in aroughly 4-6 weeks, but in the mean time what can I do to help speed up the healing and what can I do when I start back running to prevent it from happening again. I know that I have to start slow and work back up to where I was, but I just don't want this to happen again because I genuinely love to run. Also, what is something that I can do while standing to get my heart rate up? I was thinking about a modified form of shadow boxing where I just move my upper body. Thanks.
