What's your excuse?

I've heard quite a few excuses from my clients as why they didn't show up for a training session, why they didn't do or only did part of their program of exercises, why they're not keeping a food diary ...
I know an excuse when I hear it, but often when you're the one making the excuse you believe that it's the reason.
I tore a calf muscle several weeks ago and used that as an excuse to have a week of lay days. The reason I didn't do any exercise at all (I could have worked on upper body flexbility or strength) was because the injury put me into a funk - I had built up my barefoot running distance to 6km since the beginning of the year with no problems and then could barely walk. So the excuse 'I'm injured' was not the real reason; the real reason was that I needed some time to get to the doctor's for diagnosis and treatment and put a recovery plan in place. Three weeks later I'm running again.

Excuses are just that, excuses. Rather than come up with an excuse, come up with the reason. If you can't come up with the reason, 'the dog ate my homework' is as good  an excuse as any :)
