TEEN Mom alum Mackenzie McKee took to social media after a grueling workout to flaunt her toned physique.
The latest Instagram photo of Mackenzie, 28, showed her in a dark navy sports bra that exposed her entire toned midriff.
The former MTV star’s social media snap appeared to have been taken in front of the mirror inside a gym locker room.
In the caption to the mum-of-three’s story, she wrote: “2 1/2 hours at [gym]the gym is my therapy.”
From the looks of the fitness trainer’s photo, her workout routine was rigorous as her skin looked flushed and her hair was sticking out of her pulled back bun.
Lately, the 16-year-old and pregnant former has been in the news about her fitness lifestyle, especially when it comes to exercise.
Recently, the 28-year-old fitness trainer led a workout in Sarasota, Florida through her fitness brand Body by Mac.
After Mackenzie hosted her Body by Mac training session, she took to her Instagram to post a photo from the event on her profile.
In each of the images, the former reality TV star looked cheerful as she led her fitness class participants, smiling and waving her arms wide to help cheer her trainees on.
The fitness fanatic captioned her Body by Mac photo slideshow, “When I see you hitting that minute plank, I party for you! [strong arm emojis].”

Before this one, Mackenzie held another Body by Mac fitness class in September.
For this session, she kept a happy attitude as she and the group battled the hot Florida sun.
Afterwards, she posted on Instagram, “Great training, great participation! Thanks everyone for coming.”
Mackenzie has focused on training since her split from husband Josh McKee, 29.
However, fans are growing increasingly concerned that she’s overdoing it, especially after revealing her significant weight loss in a disturbing social media post.
Earlier in September, while sharing a photo of herself wearing a bikini, she confessed that she had lost a lot of weight since the photo was taken.
“I weighed 112 [pounds] here. And weigh 103 [pounds] today eating twice as much,” Mackenzie explained.
“Don’t wreck your metabolism my friends,” the former TV star added.
Mackenzie often shares photos of her fit figure online, posing in swimsuits and fitness gear.
Some fans believe Mackenzie’s fitness and health craze came after her split from Josh.
In fact, she’s always been into fitness, according to her Body by Mac website.
“I’ve always had a passion for fitness,” she wrote on her website.
Mackenzie further explained on her site that at the age of 12 she was “diagnosed with type 1 diabetes”, which “forced” her to “learn everything about healthy living”.
