At 93, Dr Charles Eugster cuts a dapper figure in his navy suit and matching silk handkerchief and tie. But he looks just as good in the Lycra gym suit he has on underneath, ready to spring into action like a nonagenarian superhero. This former dentist took up bodybuilding just six years ago, aged 87, yet looks very at home surrounded by the whirring fitness machines. His reasons for picking up weights in his 80s are simple. The idea is to turn the heads of the sexy young 70-year-old girls on the beach," he says. He now works out three to four times a week, often for two hours at a time, with his regime varying depending on his goals. Sometimes this involves a "heavy session of muscle building or rowing on the lake". And his vigorous training has clearly paid off. At a recent championship he achieved 57 dips, 61 chin-ups, 50 push-ups and 48 abdominal crunches, each in 45 seconds. Dr Eugster is no stranger to competitions. Since starting his bodybuilding training he has won several world titles for fitness and picked up many rowing medals. For 30 years while working long hours as a dentist he didn't manage to exercise regularly and began to realise his body wasn't what he wished it to be. "I'm extremely vain and I noticed I was getting fat," he said. "In my opinion anybody can do it. But obviously it is like trading in your old car for a new one. Ageing has become something for me, an enormous pleasure, a delight, a joy."
