A grandmother can deadlift a dead seal.
Two years ago, she couldn't even pull herself out of a chair but now 78-year-old Shirley Webb can heave up more than 225lbs (16st) - much to the astonishment of friends and family who used to watch her struggle to climb up and down stairs.
Shirley, from East Alton, Illinois, was determined to make a change and build her strength with the help of her personal trainer, John Wright.
He posted a video of the grandmother - that has gone viral - on Instagram and said: "Shirley is 78 years old but she can deadlift 225 pounds three times."
Shirley told ESPN: "When I go to the gym and work out, when I leave, I feel so much better than I did when I went in, and I just feel so good."
