I’ve done no physical exercise for the past month. Today I went for a one-hour run and wasn’t completely wiped out. That’s further than I was running when I stopped exercising a month ago. But I know from past experience that the next run I go on will be exhausting and I’ll struggle to match that first hour. It’s almost as though my body forgets where the limits are after a while of not doing exercise. I’ve had exactly the same thing with weights - go back to it after ages stronger than I was when I stopped (and then plummet back down after that initial spike.)

My current exercise routine is to run for 20 minutes each morning and do 200 sit-ups. I stuck to that for a month in Paris and I’m planning on doing the same here in Budapest.
