"Smith!" screamed the shrewish voice from the telescreen. "6079 Smith W.! Yes, you! Bend lower, please! You can do better than that. You're not trying. Lower, please! That's better, comrade. Now stand at ease, the whole squad, and watch me."
A sudden hot sweat had broken out all over Winston's body. His face remained completely inscrutable. Never show dismay! Never show resentment! A single flicker of the eyes could give you away. He stood watching while the instructress raised her arms above her head and -- one could not say gracefully, but with remarkable neatness and efficiency -- bent over and tucked the first joint of her fingers under her toes.
"There, comrades! That's how I want to see you doing it. Watch me again. I'm thirty-nine and I've had four children. Now look." She bent over again. "You see my knees aren't bent. You can all do it if you want to," she added as she straightened herself up. "Anyone under forty-five is perfectly capable of touching his toes. We don't all have the privilege of fighting in the front line, but at least we can all keep fit. Remember our boys on the Malabar front! And the sailors in the Floating Fortresses! Just think what they have to put up with. Now try again. That's better, comrade, that's much better," she added encouragingly as Winston, with a violent lunge, succeeded in touching his toes with knees unbent, for the first time in several years.

thank you. This is pretty much what I recalled when I read the article.
