I spotted this in one of my local patches of green space as I walked home from the [overly-expensive] gym:
Inspired treadmill design:
I do like the idea of free gym equipment, and most of the weight stuff works using your own body weight so no need for changeable weights etc. I can't imagine actually using this equipment because I don't really like the idea of people watching me work out. But still, I'll be interested to see if people do use it.
