WATCH: Kevin Hart's Wife Eniko Parrish Works Out While 9 Months Pregnant

Kevin Hart's wife Eniko Parrish was shown on video Monday exercising while nine months pregnant. Parrish took to Instagram to show fans her pregnancy workout regimen and prominent baby bump in a brief video.

On the video, Parrish is shown completing a series of bar pushups, squats, lunges and bicep curls, among other intervals. Her growing belly was on full display in the gym footage as she wore a sports bra and grey workout leggings.

"Zo loves it! he be in there just kicking away," Parrish captioned the Instagram video, referring to the baby she and Hart plan to name Kenzo.

Kenzo will be the first child of 33-year-old Parrish. Hart, 38, is a father to daughter Heaven, 12, and son Hendrix, 9, whom he had with his first wife, Torrei Hart, 39.

"Thanking God for this beautiful strong woman that I am lucky enough to still be calling my wife today," Hart wrote about Parrish on Instagram Oct. 11. "You are truly amazing....Love you. #WCW."

Parrish isn't the only celebrity mom that hit the gym while pregnant. Jessica Alba, Ciara, Nikki Reed, Heidi Montag, and Kourtney Kardashian are among a list of Hollywood moms that have kept up with their workout regimen as expectant mothers.

"I intend to keep exercising for as long as possible while pregnant," Serena Williams told The Telegraph of her own pregnancy in August. "I want the baby to be healthy and for that, you need a healthy life."

It is safe to workout throughout the course of a pregnancy, in most cases, if done properly. Expectant mothers are only recommended to avoid exercising if they're experiencing an abnormal pregnancy.

"Physicians aren't trained to counsel pregnant women about exercise," James Pivarnik, vice president of the American College of Sports Medicine, told Parents magazine. "It's a rare bird who keeps up with the exercise and pregnancy literature. If a woman is having a normal pregnancy, she can continue to exercise, and the upper limit of the level can be reasonably close to what she was doing before pregnancy."

There have been reported benefits to working out when pregnant, including improved mood, increased energy, reduced backaches and better sleep.

"I tell my clients to think of pregnancy like a running a marathon," Joanie Johnson, co-founder Fit Pregnancy Club (FPC) in New York City, told Shape magazine Oct. 17. "You wouldn't run a marathon without training, so why would you go into the most physically taxing event of your life without conditioning your mind and body for it first?"
