Ow! Don't you hate when that happens? You're doing what you can to get yourself back in shape, and then you get injured. Frustrating!
I'm hoping to get back into running, but right now it's too hot. So, I got myself a jump rope and I have yet to give it a go. I think you're just the inspiration I need to start hoppin'!
Keep it up - you'll be back to it in no time!
