Jenna Dewan Shows off Extreme Body Workout After Channing Tatum Breakup

Jenna Dewan is working on her fitness amid her divorce from Channing Tatum.

The actress took to Instagram Wednesday to share a snippet of her workout routine with JJ Dancer, and rookies should probably not try it at home.

"Late night gym sessions with @iamjjdancer are NO JOKE," Dewan captioned a snippet on her Instagram, before linking to the full clip on her YouTube channel.

First reported by Entertainment Tonight, the mother of one knocks out some intense barbell hip thrusts, yoga ball tuck ups, lunges and deadlifts in the video.

"I'm officially dead," the Step Up star tells her fans after the workout. "Thank you JJ Dancer for the late night workout. Mama's gotta get it in!"

Dewan also sported a "Year of the Woman" t-shirt from the My Sister campaign against sex trafficking. The organization aims to prevent sex trafficking, empower the population, provide after-care for survivors and offer growth opportunities to at-risk women through the sale of their statement-making apparel and accessories.

The World of Dance host and Tatum announced their split on April 2, after nine years of marriage. They have one child, daughter Everly.

"We have lovingly chosen to separate as a couple. We fell deeply in love so many years ago and have had a magical journey together. Absolutely nothing has changed about how much we love one another, but love is a beautiful adventure that is taking us on different paths for now," the couple said in a statement shared on their social media accounts.

"There are no secrets nor salacious events at the root of our decision -- just two best-friends realizing it's time to take some space and help each other live the most joyous, fulfilled lives as possible," the couple said. "We are still a family and will always be loving dedicated parents to Everly."

They continued, "We won't be commenting beyond this, and we thank you all in advance for respecting our family's privacy."

Since then, Dewan has been seen in Los Angeles without her wedding ring on. She dropped her Taum's last name from her social media accounts and has gotten backlash for beginning to post photos in her lingerie on Instagram.

"That was fast. Most people are not in a hurry but it seems like she been over it for awhile," one fan wrote, notes PEOPLE.

Another wrote, "Remove Channing check. Remove Tatum from name check. Remove clothes for [Instagram] pic check."

However, most of the comments defended Dewan's right to post whatever she wants on her own Instagram page. Some noted that we do not really know what led to their break-up, as the couple have been very private about their split.

"How funny people complaining your in your underwear, but would probably have no problem seeing Channing in his," one supporter wrote.

"To the haters, did you get lost in all that typing to see she I promoting intimate wear and working, you have no idea how this woman feels in regards to her break up," another fan wrote. "Unless you walked a minute in her choose then stop bullying her for doing what she does to make a living."
