Think you know what old people look like? Frail, walking unsteadily and their back bent over from the weight of their head? Spindly arms and legs, bulbous elbow- and knee-joints? Think again!

Have a listen to what 77-year-old powerlifting grandmother Willie Murphy has to say about lifting weights, how the work in the gym makes such a difference to her life out of it.
And as for Darshan Singh Gill, he is equally impressive.
Maybe you don't want to go in the gym and lift weights 6 times a week, but then again maybe you don't want to be able to leg-press 1,200 pounds, either. Put in the work required to get to where you want to get to.
