In her 30s Kiran Dembla was a full-time stay-at-home mum living in the Indian city of Hyderabad. She spent her days cooking and cleaning and caring for her children. Kiran always had the sense that something was missing, she describes feeling a 'blankness', but it was only when she discovered that she had a blood clot in her brain that she decided to do something about it.

The medication she was taking was causing her to put on weight so she joined the gym. That decision set her on the path to completely transforming her life - these days she's a celebrity trainer and a star bodybuilder. But it hasn't been an easy road - cultural and family expectations have often been at odds with her own aspirations.

Also on the programme, our reporter Saskia Edwards goes in search of the elusive creator of what must be one of the most maddening games - the Rubik's Cube. On route she meets one of the fastest cubers in the world, Feliks Zemdegs. He can solve the puzzle in a matter of seconds but even he can't tell Saskia where she can find its inventor - Erno Rubik.
