The gym

You wander into the gym and take a look around. It's still early morning so not particularly busy but there's enough people here to give you some ideas. In one corner two women are working out on some kind of weights machine, clearly competing with each other. On the other side of the room a slightly overweight man is running on a treadmill, an attractive woman talking to him, presumably his coach or something similar. From the edge of the room you can also hear voices from the changing rooms too.
