Apparently I have a defective buttock. I have been reliably informed, by my Pilates instructor, that it has gone to sleep to the point of being comatose which means that my right buttock cheek is having to carry the lazy little bastard. What this means, in practical terms, is that my right buttock is constantly poking my pain sensors in a desperate attempt to get my attention and tell me to give it a rest for a couple of days.
The human body is pretty canny and, whilst your brain is busy telling you that exercise = feeling great, your body is saying ‘hang on a minute I’m knackered’. At this point, as our bodies are infinitely more intelligent than we give them credit for, they will force us into a period of rest whether we like it or not.
