TEEN Mom Mackenzie McKee has flaunted her fit figure in a new social media post.

The mom-of-three showcased her washboard abs while flexing in booty shorts and a sports bra.

Promoting her personal fitness business, BodyByMac, 27-year-old Mackenzie took to Instagram to share some reflections with her followers.

In the accompanying picture, she flexed her bicep alongside the other two personal trainers who work for BodyByMac.

Mackenzie, who is married to Josh Mckee, showcased her stunning abs and bulging muscles as she smiled for the picture.

A black sports bra allowed the MTV star to fully showcase her impressive physique.

In the caption, she wrote: “It’s been an entire year since this business went from one trainer to 3. 

“Adding strength training and muscle building was the icing on the cake here.”

In her Instagram Stories, the health fanatic also responded to a follower’s question asking: “How do you get abs? Struggling with love handles.”

She replied: “Abs are made in the kitchen.”

The latest update from gym-rat Mackenzie comes after she showcased her butt and toned tummy while paddleboarding.

The reality star updated her fans as she enjoyed some time in “Florida’s nature”.

Taking to Instagram, Mackenzie shared a series of images of her and her friends on the lakes in Sarasota.

In one image, she showcased her immaculate abs in a purple sports bra that featured a zip at the front.

In another, she gave fans a look at her behind, wearing just floral bikini bottoms.

She went make-up free and tied her hair back in a ponytail as she enjoyed her time outdoors.

The Oklahoma native also flaunted her tiny frame earlier this month in a leopard print bikini.

Mackenzie adopted an impressive yoga pose for one of the saucy snaps.
