Her online influence is as hefty as the iron she pumps, with tens of thousands of followers. Jen Sinkler, powerlifter and trainer at the Movement Minneapolis, regularly posts jaw-dropping photos and videos of herself and her workout buddies dead lifting, bench pressing and back-squatting with enormous weights. Images of her bulging biceps and juicy quads run counter to the waif-like female aesthetic in our culture. But make no mistake: Sinkler embodies strong and feminine, hoisting barbells while sporting perfect makeup and fashion-forward gear. Her Twitter profile pretty much says it all: "Never, ever without lip gloss." jensinkler.com
