Do you have ‘office bum?’ Nutritionist sounds the alarm on rise in flat posteriors — here’s what you can do

This could be a danger to your health – let’s not talk about it.

A nutritionist is sounding the alarm over ‘office bums’, saying a flat posterior could pose serious medical problems.

Expert Annabelle Smith says shapeless boots are extremely common due to our sedentary lifestyle, with many workers sitting continuously for up to 9 hours straight.

“The combination of not having an active life outside of work or specifically exercising the glutes – often coupled with a poor diet – will see even the best posteriors suffer in terms of a flat, untoned butt,” Smith explained in an interview with The Mirror on Thursday.

She claimed that big, generous butts are idolized in our culture, which causes anxiety in those who are not lucky enough to have such a posterior.

However, a flat “office bum” doesn’t just pose aesthetic problems.

According to The Mirror, this “can lead to more dangerous conditions”, including “dead butt syndrome”.

Healthline states that this condition “results from the gluteal muscles essentially ‘forgetting’ their primary purpose: supporting the pelvis and keeping your body in proper alignment.”

The syndrome can cause stiffness not only in the glutes but also in other parts of the body, causing chronic pain.

Smith says you can build a pert posterior – but you’ll have to work hard (or, more accurately, at it).

“Build muscle, keep body fat at a reasonable level and stay active,” she implored, saying that sitting at a desk is no excuse for having a flat butt.

Meanwhile, other experts told the Mirror that squats, side planks and lunges will specifically help strengthen the glutes and develop your butt.

A move known as the “monster walk” will also help.

“Start by placing a resistance band around your ankles and position your feet slightly wider than hip-width apart,” an expert from British fitness company Mirafit told the Mirror. “Take small steps forward at a slow pace. You should feel a burning, activating sensation in the outer muscles of your glutes.
