Mary Duffy Deadlift

We witness some incredible feats of strength almost every day, but when they are performed by a 73-year-old, they become even more impressive. In this case, Mary Duffy surprised the fitness and strength communities, by hitting a deadlift that is 2.5x her bodyweight. Despite the fact that Mary performed the deadlift on a trap bar, it was still incredibly heavy, weighing in at 250 pounds (113.4 kilograms) and an additional 50 pounds (22.7 kilograms) of chains

To make it even more impressive, Mary Duffy’s deadlift was raw, since she only used a lifting belt and wrist wraps. It was not easy by any means, as Mary really had to grind to lock it out, but it paid off in the end. Mary captioned the Instagram post as “Finally!!!!!”, making it evident that she has been chasing 300 pounds (136 kilograms) for a while.
