Yep, there are enough 70-year-olds with six packs out there to make a documentary about it. In this one-off special for Channel 4, we meet some of Britain's oldest muscle men, as they work towards the competitive World Bodybuilding Finals in Miami. The programme takes an alternative look at what it is like to be old in today's rapidly changing world, and meets contestants including 79-year-old Eric Dowie, who is the oldest man in the competition and hopes to retain his 2014 title of Over-70s World Champion.
