Montana Brown poses in underwear to show off her 12 months postpartum figure as she documents her fitness transformation after giving birth to her second child

Montana Brown showed off her 12-month postpartum figure on Instagram on Monday.

The former Love Island star, 30, who welcomed a baby girl with her fiancé, Mark O'Connor, around this time last year, took to social media to document her fitness transformation after giving birth to her second child. 

In one short video clip, Montana looked incredible in a seamless blue underwear set, posing up a storm in her bathroom mirror. 

Documenting her fitness journey over the past year, Montana shared with her followers several clips of herself working out in the gym with weights, going on outdoor runs, and doing cryotherapy.

In another short video clip, Montana showed off her toned figure in a seamless lilac bra and blue bottoms. 

She captioned the post: 'Falling back into fitness has been my saviour this year. It’s been such hard work but there is some pretty incredible fitness communities around.

She continued: '@aeptgym thanks for supporting me from 2 months postpartum #fitness #postpartum.' 

AEPT gym is based in Aston Clinton and run by Alex and Emma Morgan.

Montana's post comes after she revealed she is ending her breastfeeding journey.

The Love Island star is mother to Jude, two, and Miley, who turns one next month, with her fiancé Mark, and often chronicles her parenting online. 

Earlier this month, she shared a lengthy post revealing she was stopping breastfeeding Miley, as feeding and co-sleeping had left her 'irritable, impatient and angry' while suffering poor mental health due to 'not sleeping in three years'. 

In a post over the weekend, Montana showcased her incredible figure in a bikini and discussed how she is 'committed to feeling her best'. 

In her post regarding prioritising herself, she wrote: 'I feel like I’ve co-slept for 3 years, breast fed and just given every damn inch of myself to those babies and it has felt really nice to spend more time to focus on personal goals.' 

In the post, Montana wrote: 'How I really feel about stopping breastfeeding… Completely Relieved! I’m going to be honest, I have really not enjoyed breastfeeding the last 4 months... 

'I have persisted because I know it’s good for Miley and we’ve had things planned which I know it would be more convenient to continue...

'It’s a truly beautiful and natural thing which I’m extremely grateful to be able to have done for both my children HOWEVER personally it has ALWAYS come at a cost of my mental health...

'I think because I’ve breastfed AND coslept I have always reactively fed with little routine because I do not like the idea of scheduled feeding...

'I’ve not slept properly in 3 years… because I breastfed Jude for 10 months and Miley nearly a year and the lack of sleep has made me feel like an insane person...

'More irritable, less patience, more anger. I just want to say here and now, there is no award for breastfeeding the longest, I have really struggled with my sleep on both occasions due to breastfeeding through the night...

'So if you’re a mum struggling breastfeeding please know it is ok to stop and prioritise yourself if it’s making you unhappy. Happy mum, happy baby. I’m so glad I’m done. Thank you and goodnight.'

She previously shared her bikini-clad, in which she followed the social media trend of listing what she is 'walking into 2026 with'. 

Her list comprised: 'More focus, better fitness, less f**ks to give, more girl time, more boundaries, therapy, less toys for my kids, more adventure, better health, better phone ettiquette, more cooking with my kids'. 

She added a caption reading: 'Proud of myself for committing to feeling my best after 2 babies back to back. I don’t know if any other mothers relate but I felt so shell shocked after Miley and was desperate to feel back to myself and have some confidence...

'I feel like I’ve co-slept for 3 years, breast fed and just given every damn inch of myself to those babies and it has felt really nice to spend more time to focus on personal goals...

'Mums, don’t feel guilty you have brought humans into this earth and you deserve some time to focus on yourself'.
