"It's been three months now working out with @senada.greca. We lift weights for two hours daily and do 5 or 6 days a week... This exercise is called a 'split stance good morning.'"

The SKIMs owner explained that her initial goal "was to gain muscle and be strong," and as of late, she has begun seeing results.

"I see such a difference already. I'm proud of our commitment together. It always starts with small goals," she wrote in another video.

The reality star could be seen jamming to a few hits during the session, including Taylor Swift's You Need to Calm Down.
