Arms of steel!

Khloé Kardashian showed off her incredible arm (and back, and ab!) muscles as she destroyed her workout on Snapchat.

“If I can do it. You can do it. It all starts with day 1!” she captioned a video of the snap, posted on Instagram.

Kardashian, 32, ab rolled her way to a tighter core (though it looks seriously ripped already!) on Thursday, and took to the hills for a sweaty run on Friday.

In a series of Snapchat videos, Kardashian did a hardcore trail run up a mountain with her trainer Don – all in a black long-sleeved shirt and pants.

“That was so hard today but Don and I made it back safe, we want you guys to know,” she says in the video. “Happy Friday, and I feel like I’m dying!”

Clearly Khloé is ready for the weekend!
