Man, 67, fights cancer with 'superhuman exercises'

Impressive footage of a 67-year-old man fighting colon cancer with an extreme work-out he's developed himself.

The video, filmed in Louisville, Kentucky, USA on October 9, shows Robert Durbin, talking viewers though his story since his diagnosis earlier this year.

Doctors were surprised he was able to work out at all while undergoing chemotherapy, but as this clips shows, he can do more than most healthy people can at the gym.
