How does “Arrow” star Stephen Amell keep those incredible Oliver Queen muscles ready for superhero duty? A video posted to Facebook by the actor makes it clear that a lot of hard work goes into those abs.

Amell posted a video of himself working out at the Tempest Freerunning Academy in Los Angeles on Thursday (June 4). In it, the “Arrow” star runs all over an obstruction-filled gym, leaping and climbing his way up and down walls. He even fits in a salmon ladder!

Alas, the final jump proves to be a little too much even for Amell, leaving the actor hanging — literally.

Maybe he’ll make it next time though — because Amell will definitely need to be back if he wants to be in-shape for “Arrow” Season 3 in the fall.
