Jenna Dewan hits the gym hard!

The 37-year-old actress took to Instagram on Wednesday to share a taste of her workout routine with JJ Dancer -- and it's clear she's not messing around. "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. 

The mother of one knocks out some intense barbell hip thrusts, yoga ball tuck ups, lunges and deadlifts in the video, before Dancer documents Dewan's signature late-night move: "Jenna squats." 

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

While Dewan let her followers into her exercise routine, her ex, Channing Tatum, made his first red carpet appearance since their split at CinemaCon at The Colosseum at Caesars Palace in Las Vegas, Nevada, on Tuesday. Tatum and Dewan announced their separation after eight years of marriage earlier this month. 

The former couple has remained friendly, however, with Tatum even "liking" one of Dewan's recent Instagram posts, in which she posed in sexy lace lingerie.
