Heather Rae El Moussa has revealed the secret to the washboard abs she has achieved after giving birth to her son Tristan.

The 37-year-old and her husband Tarek El Moussa got married in 2021 and then welcomed their little boy into the world in January 2023.

Since then, Heather has been working with trainer Paulina Hefferan on a regimen that has honed her body back into exquisite shape.

She treated her more than three million Instagram followers to a jaw-dropping snap of her chiseled abs, next to a pH๏τo of her softer midriff taken on an earlier date.

In her caption, she unveiled the ‘exact routine’ she relied on to enhance her ‘gut health’ and her ‘digestion’ and attain the figure she wanted.

‘Honestly, after my baby I struggled with bloating & I never had before, healing my gut changed everything: here’s my exact routine-,’ she wrote.

Her ‘Supplement PM routine’ consists of two capsules of Reset PM Gut Cleanse from her trainer’s own line Paulina Fitness.

Tagging Paulina, Heather gushed that ‘I swear by these’ supplements and added that she and her husband ‘are both obsessed’ with the product.

Meanwhile, Heather’s ‘AM routine’ is comprised of taking a ‘Probiotic’ and ensuring that she has mixed ‘Electrolytes into my water.’ 

In a picture of her supplements, she disclosed that she is partial to the Ultima Replenisher Broad Spectrum Electrolyte Mix in the watermelon flavor.

She also apparently enjoys the Organifi Original Glow raspberry lemonade mix, which is billed as providing ‘natural collagen support.’

Heather’s other tips include ‘Limiting gluten, limiting soy (a lot of vegan food contains a lot of soy), and daily walks in the AM with Tristan improved my digestion so much!’ she gushed in her Instagram caption.

Her Instagram album about her gut health included a glimpse into her ab workouts – a video of her performing a set of knee lifts with a medicine ball.
