In other news, my leg is still sore, but people keep giving me cake, so that’s good. I went back to work today, on my crutches, and it was completely exhausting. On the other hand, it’s probably giving my arms some good exercise, which might just make up for not going to circuit training this week (I’ve been forbidden from doing so on account of my injuries, despite my protests that I’d be perfectly capable of doing shuttle runs and squats and exercise bikes like this, right?).
