Mike Montgomery (Cody Christian) is taking martial arts lessons on Pretty Little Liars and it looks like he's been working on his muscles in real life too.

The PLL actor took to Instagram yesterday (August 5), posting a photo of himself during a hike in Idaho. Along with the shirtless pic, he wrote, "beauty surrounds us. It's the matter of whether you take the time to see it." Oh, we most definitely see it now, Cody!

Check out the photo below of Cody showing off his toned biceps and chiseled back, and then let us know what you think in the comments. Are you crushing on this brunette hottie, or are you too preoccupied with what's happening with him on-screen? Sound off in the comments!

Catch the next episode of Pretty Little Liars on Tuesday, August 6, 2013 at 8 p.m. ET/PT onĀ ABC Family.
