GREAT!! Two days into my plan....I went for a brisk walk this morning and decided to use the hills at the local park for some added resistance. Popped a muscle in my calf. It felt like I was hit with a steel pipe. It floored me. I struggled to get home and I've finished icing it and it's now in a tensor. How am I going to get decent enough exercise now for the next few weeks?

Upper body resistance band training from seated position? Can't stand that's for sure.

Any tips on maintaining some form of fitness while nursing a leg injury?
