Khloe Kardashian has been putting in the WORK at the gym.

The Good American cofounder showed off her backside, and no we aren’t talking about her derriere.

We are talking about her actual back.

Khloe took to Instagram to show off her toned body on Tuesday, February 1.

She posted two photos taken about three months apart.

In the first photo she looks super lean and cut. In the second photo you can see Khloe’s muscles bulked up.

She captioned the pics, “About 3 months apart 💪🏽 let’s go we are sculpting my back and arms.”

Koko’s famous friends immediately left words of encouragement in her comment section.

Jen Atkin commented, “My hero. I’m so impressed with your dedication Khloe. Years and years of waking up and committing to YOU. I love u.”
