For anyone who doesn't know who Paige Hathaway is, this is a woman who is purely memorable.

Hathaway is one of Instagram's most popular hits with more than three million followers. She's to promote health and fitness on her page where she shows off her slender figure and hard muscles.

Over the weekend, she added a photo that shows off her strong abs and massive biceps. She stands outside with a little dog as she dons a black and white top with tight pants.

With her hair braided backwards, Hathaway flexes her arm and flaunts her hard stomach muscles that show how hard she works to get that way.

In the caption, she wrote that this is her "favorite type of Saturday."

While her arms and belly are completely fit, she's muscular in other areas of her body too whether it's her legs, behind or back. See some of her popular photos below.
