Lara Trump has left her fans so stunned by her bulging biceps that some are asking if they are AI generated.

The 43-year-old Fox News host, who is married to President Donald Trump's son Eric Trump, impressed her social media following with her eye-popping muscle definition earlier this week.

Taking to Instagram, Florida mother-of-two Lara showed off her toned arms and ripped abdominals as she posed in a red crop top from her clothing line.

Lara wore the striking garment, which featured 'USA' in large white font and the flag underneath.

Captioning the upload, she wrote: 'American spirit never goes out of style.'

Taking to the comments, dumbfounded followers couldn't help but comment on her enviable physique.

'Are those guns legal in America?' one asked while another simply wrote, 'insane muscles.'

A third continued: 'I love everything about it! The hat, the shirt, the abs, the arms. Looking good Lara.'

'You get more beautiful and more ripped every time I see you,' observed another.

'Is your body real or AI generated?' asked a fifth.

Lara has made it no secret that she pours blood, sweat and tears into her fitness regime. 

Last year, she took the Daily Mail around the fitness center and movement studio at Trump's Jupiter golf club in Florida.

There, she revealed her go-to moves include hammer curls and meticulous bicep curls, which have helped to get her signature arm muscles.

But she advised anyone trying to emulate her routine to make sure they work their shoulders to get the defined look she touts.

To get shredded abs, high, low and side planks are a must.

Daily squats are also essential, Trump claimed, since legs and glutes make up several of the largest muscles in the body and must be maintained.

She revealed that one of the biggest time wasters at the gym is spending time staring and scrolling on a cell phone – like she joked her husband Eric does and ends up doubling the time needed for his gym sessions.

Beyond the gym, Trump said she also will try to make it to Crossfit and pilates classes and will compete in triathlons to provide variety and make sure that staying in shape is fun.

Lara has not been shy about showing off her workout routines with her followers online and regularly posts herself in athleisurewear.

Over the past six months, she has posted online about hitting the mat for Brazilian Jiu-Jitsu training, indulging in crossfit training and doing a weighted workout with her husband.

In May, she showed Fox News viewers inside her morning cycling routine which begins at 6.10am.

In a video that was aired on the network, she revealed that she began her day with coffee with collagen and creatine.

Lara launched her fitness apparel brand, the Lara Trump Collection, in November 2024.

Inspiration for the brand, she said, came from a desire to show that women 'could do anything the guys could do.'

'In a world of fast fashion and outsourced production, Made in America clothing stands as a powerful statement — of integrity, craftsmanship, and national pride,' her website reads.

'At the Lara Trump Collection, we're proud to say every piece is designed and manufactured right here in the USA.'
