Shay Mitchell (Emily) looked dazzling in her swimwear during her recent Hawaiian getaway, but how does she have such a rockin' bikini bod? No, it isn't just from running away from "A" and doing swim laps on-screen.

The Pretty Little Liars actress took to Instagram yesterday (July 10), revealing her newest workout routine. Along with a photo of herself and a friend looking stylish on stationary bikes, Shay wrote, "Workout done with @michaelablaney at @aurapulse #auracycle !!! #zoomzoom." If taking spin classes is the secret to getting in Shay shape, then we think we just discovered our love for biking!

Plus, aside from just sweating it out during spinning, Shay can also be seen jogging around her neighborhood. Hey, between all of this exercising and maybe some martial arts lessons from Jake (Ryan Guzman), Shay's character Emily will be ready to fight off "A" any day!

What do you think of her fun workout routine? Weigh in below.
