Growing A 'Thut'?  Our lazy lifestyles are causing a rise in the thigh-butt.  No, really, I'm not kidding you. 

Its not that I don't believe the problem exists,  just  that it seems like most people, or, should I really say most women (because the thut is a girl thing), don't need one more body part to obsess over.

Fitness experts say that our sedentary lifestyles mean more women are losing the definition between their thighs and their butt than ever before.

 

 

 

The thut is when the muscles on the back of a woman's legs are undeveloped… leading their butt and thigh to appear as one.

 

 

 

The 'thut' as it was coined  by http://NYmag.com, is when the muscles on the back of a woman's legs are undeveloped - leading their butt and thigh to appear as a single piece of anatomy.

According to experts, the issue is caused by a lack of targeted muscle tone and does not reflect the physical anatomy for a flat derrière.

'It's not the same thing,' Cynthia Shipley, an instructor with True Pilates told MailOnline. 'You have to look for definition, if the hamstrings are developed and if the buttocks is lifted.'

The thut's muscular origins are part of a postural support group that help dictate standing, lifting, and walking movements.

The grouping's lack of development can be attributed to a shift in working culture, where many Americans sit in a desk chair all day rather than working in manual-labor-intensive occupations.

Experts say there are several different ways to get rid of the thut including squats and lifting, rowing or floor exercises.
