Fitness has acquired a lot of admin.

There are classes to book, rings to close, zones to reach, programmes to follow and watches that congratulate you for standing up as though you have personally overcome adversity.

All useful, perhaps.

But somewhere along the way, ordinary movement started to look slightly unofficial.

A walk to the station became transport. A walk across London became something you happened to do. Carrying shopping home apparently stopped counting the moment nobody called it functional training.

That is strange.

Your body is less interested in the branding.
