If you're sincere, keep in mind that more than half of her job is being a spy. Overly muscular women, unfortunately, stick out quite a bit, which is the opposite of what being a good spy is. Particularly when it seems like she's put into roles where it's not expected that she'd have an outward appearance of strength.
She's fit, and she probably has the benefit of the Soviet version of the super soldier serum to increase her fitness past what her appearance would be. (I don't think we know that for sure MCU; I usually just go with it when I'm writing her)
