Mary Kalisy, a Russian beauty with a lithe 47kg, 171cm frame, enters the Fit18 studio for a casting session that's as much about her physical prowess as her looks. She stretches and warms up, her skin glistening with sweat as she goes through a series of exercises, her toned muscles contracting and releasing. Dick Long watches, his eyes appreciating the Russian model's form, the tension in the room palpable as Mary's fitness outfit clings to her body, leaving little to the imagination.
