The Ashleys are having a gym showdown!

Both Ashley Tisdale and Ashley Greene hit their West Hollywood and Studio City gyms, respectively, Thursday in oversized black shades, cropped leggings and ponytails, but they seemed to have sweated it out very differently.

A very blonde Tis looked like she barely broke a sweat as she showed over her svelte figure in a white tank, while the Twilight star was practically drenched from head to toe.

Hey, everyone works out differently!
