Documentary exploring the ageing population through the eyes of 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. Cameras also follow Jimmy, who is desperate to reclaim the title from Eric, and 76-year-old Roger, who is determined to succeed with the help of his right-hand lady Joan.
