In her latest YouTube video where she shared her morning routine, Anfisa also showed her fans a peek into her unbelievable ab workout!

Anfisa's morning routine

The video, which Anfisa said was filmed by her husband Jorge, shows the Russian native waking up and getting ready for the day. Anfisa keeps a bottle of water on her bedside table so she can get hydrated even before getting out of the bed.

According to the reality star, one of her beauty and fitness secrets is that she tries to drink at least two liters of water every day.

Before having breakfast, Anfisa makes sure to do a short tummy workout, which she calls the "vacuum exercise." She demonstrated this in the video and it looked truly astonishing. Watch the video below to see for yourself!

"It helps to make your midsection tighter and waist smaller," Anfisa said.

What is the 'Stomach Vacuum' exercise?

In the video, Anfisa can be seen doing this type of exercise by sucking in her breath and wiggling around her ab muscles. It looked crazy and intense--but judging from the sexy star's bare midsection, this exercise must totally work!

According to, the stomach vacuum exercise is being practiced by fitness enthusiasts including yoga, CrossFit practitioners, and even bodybuilders. It's done by sucking in your belly and exhaling all the air out of the lungs and diaphragm. Tighten your abs and hold for a full minute.

This technique will not only give you a flat midsection; experts say that the vacuum exercise is a powerful and effective way to strengthen your core and give you good posture.

Best of all, anyone can do it anywhere and anytime.

In her video, Anfisa said that she still hasn't mastered this workout. But it seems that the "90 Day Fiance" star totally knows what she's doing! By the end of her clip, Anfisa showed off her toned body by wearing a form-fitting top and skinny jeans.

Jorge and Anfisa return to reality TV

Anfisa is surely enjoying her new-found fame on YouTube. Inside of just two months, since she created her channel, she's already reached 100,000 subscribers. This is no simple feat--most YouTubers attain this status after months and months of posting content.

Of course, Anfisa has her "90 Day Fiance" fame to thank for her online success. On Sunday, she and her husband Jorge will be back on the controversial reality show for another season. In the new season sneak peek, Anfisa is seen worrying over the possibility that Jorge has fathered a child with his ex-girlfriend.

“If this kid is really his, I don’t want to have anything to do with Jorge ever again,” Anfisa says in a confessional.

It looks like fans are in for more drama and hysterics between Jorge and Anfisa! "90 Day Fiance: Happily Ever After?" Season 3 premieres this Sunday, May 20, at 8 PM on TLC.
