Grandmother Mary Duffy becomes international powerlifting champion in her 60s

Mary Duffy, 71, from Trumbull, Connecticut, (pictured L-R, inset) started working out at the age of 59 after piling on weight following the death of her mother in 2007, losing nearly 50lbs within one year. She quickly became hooked on weight lifting and now spends around 20 hours a week pumping iron in six hour gym sessions, and has more than 30 state and world records to her name - insisting she feels better than she did 30 years ago (bottom inset).
