Another muscular male back is the focal point of this image of a workman hauling on a strap.
Manual labour is not highly valued in economic terms but gay men can appreciate it as a priceless expression of masculinity, one that most of us can only realise through the artificial process of gym exercise.
Shame about the baggy jeans though.
It's by the artist Steve Huston who makes something of a speciality of images like this,
involving boxers and workmen.
