Teen mum Mackenzie McKee has a flex-off with son Gannon, 11, as the couple flaunt bulging muscles and abs in new pictures
TEEN Mom star Mackenzie McKee and her son Gannon have left fans stunned with a new photo that shows off her impressive abs.
The MTV grad has been flaunting her fit physique on social media for some time, promoting her fitness classes and showing off her progress.
Mackenzie, 28, took to Twitter to pose alongside her eldest child, leaving fans in awe of not only how much the boy has grown but also how strong he and his mum are.
In the first photo in the bunch, the Oklahoma native and Gannon, 11, lifted their shirts to reveal their abs.
Both showed well-trained six-packs.
A second snap showed them each flashing their biceps while standing side by side.
Gannon cocked his head to admire his muscles while Mackenzie smiled straight into the camera.
The pair again flashed their bicep muscles for the camera in a third snap, this time both standing to the side and pulling faces at the lens.
Finally, Mackenzie and Gannon struck another pose with arm muscles exposed.
For his part, the boy smiled and looked straight ahead while his mother held both arms up in a pose and smiled broadly.
The caption read: “My boy may have better abs than me but I can still pass him. Ok, but why is he getting so big?[?]”
Fans flocked to the comments to rate both her fitness progress and Gannon’s adult looks.
One fan wrote: “Sweetie.”
Another commented: “No way is he that grown up!! Goes so fast.”
A third fan chimed in: “He’s getting so big! And you’re doing great with your kids. I’ll never understand why MTV took you off the show.”
Another commented: “Oh very cute! I used to think he was Josh’s twin, but now I’m seeing a lot of you guys as he’s getting older!”
Earlier this week, Mackenzie wowed fans again, this time with her own fitness advances.
The star shared a video of herself working out with dumbbells on Instagram and urged her fans to join her in her workouts.
She showed different exercise routines that her followers could do with the dumbbells to strengthen different muscles.
The Teen Mom star also promoted her online personal exercise service, Body By Mac.
In the video, she showed off her figure while wearing a blue skin-tight sports bra along with a pair of black booty shorts and matching sneakers.
Fans are now used to seeing Mackenzie’s workouts and physique.
Last month, she flaunted her muscular physique while enjoying a little downtime by a Florida river.
She stunned fans with a series of photos showing her paddling.
Mackeznie flaunted her abs and toned legs in a sparkling blue bikini.
In some of the photos, she smiled defiantly as she stood on her pink board and raised her paddle over her head and into the sky.
Another photo showed her painted toenails as she relaxed on the board in the calm water.
A final pair of pictures showed the star sitting and paddling on her boat.
In one shot, her butt was partially exposed.
She proudly captioned the post, “Sunshine and salt water give me LIFE!”
