TEEN Mom Mackenzie McKee has shown off her toned physique in a sports bra and tiny shorts in fiery new photos.
The reality star took to Instagram to post the sexy snaps.
In one, Mackenzie, 28, posed in a lunge while flexing her strong arms at the camera.
She rocked a blue tie-dye bra top, black booty shorts, and her blonde locks styled in two French braids.
The photo appeared to be taken in the living room of her Florida home where she resides with her three children: Gannon, 11; Jaxie, nine, and Broncs, six, whom she shares with her ex-husband, Josh McKee, 29.
In the following snap, she shared her healthy snack of a bowl filled with various fruits, topped with nuts and chia seeds.
And the last pic captured Mackenzie again flaunting her rock-solid abs in workout gear and multiple water bottles tied around her waist.
She appeared to have just concluded a run as she sported no makeup, and her hair in a ponytail, giving two thumbs up at the lens.
The Body By Mac founder included a lengthy caption encouraging her followers to adopt healthy habits for their mental and physical well-being.
Mackenzie regularly shows off her fit figure and intense exercise regimen on social media.

Earlier this month, the Teen Mom OG alum showcased her strong arms and legs while performing deadlifts in a social media video.
She also shared a video of herself working out with dumbbells while encouraging her fans to work out with her.
The young mom suggested different exercises to do with the dumbbells to help strengthen the muscles.
Mackenzie’s love for fitness also appears to have rubbed off on her children.
The Oklahoma native and her eldest son, Gannon, recently stunned fans after exposing their impressive abs.
In the first photo, the mother-son duo lifted their shirts to expose their mid-sections, where they each had six-pack abs.
A second snap showed them flashing their biceps while standing side-by-side.
Gannon turned his head to the side 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, with both standing to the side, making faces at the lens.
Lastly, Mackenzie and Gannon struck yet another pose with their arm muscles exposed.
The boy, for his part, smiled and looked straight on while his mom held up both arms in a pose and smiled wide.
She captioned it: “My boy may have better abs than me, but I can still out run him. Ok but why is he getting so big?”
The posts came after Mackenzie admitted to fans that she couldn’t get ahold of her children’s father, Josh.
It happened during an Instagram Q&A when one fan asked about her custody arrangement with her ex-husband.
The MTV alum responded: “Can’t even reach him,” with a shrugging emoji, “Wish him well though.”
Mackenzie and Josh split last year after almost a decade of marriage.
The exes have since moved on as Mackenzie debuted her new man in December and has shared photos of him bonding with her kids.
