I was going to do a run this morning, but the sole of one of my feet is a bit sore – maybe burised or something. So I just did some other exercise… I did 20 situps, and 20 pushups. I did cheat with the pushups, doing them on the stairs. This makes them easier since I have not done any for a while. I dont think it would have been a good idea to do any more either pushups or situps… 20 of each was enough.
