Nor are their moves, as they break into carefully
choreographed, though unfamiliar, dance routines.
With their big build, turbans and beards, the Sikhs are a stark
contrast to the clean shaven, lean models preferred by designers all
over the globe.
But under the watchful eye of their mentor, Gurmeet Singh Gill,
they hope to change the face of fashion.
Hitting back
The whole idea for his Sikh agency was inspired by his own rejection.
"I started this agency because I wanted my Sikh brothers to walk on
the ramp in their turbans.
"Basically I was rejected by one of the leading modelling agencies in
Delhi. I told them that I want to be a model, please give me a chance
- but they refused me.
"They use to laugh at me, now I'm laughing at them," he says.
The 18 would-be male models get up at 0530 every morning to undergo
the rigours of the gym.
They may be pushing against prejudice, but there is no doubting their
commitment.
Each has paid $500 for the week-long course.
The one thing they are not lacking is self belief.
'Macho'

Jaskirat Singh Rekhi, 19, is one of the aspiring models.
"Sikh models are very macho, very masculine and very passionate. They
are not like those hanky-panky guys, you know those girl-like guys,"
he says.
But part of their training is to practise the not very masculine art
of yoga.
Most of them have never tried it before.
But it's seen as essential for flexibility and what is described as
"grooming the inner self".
It's hoped that all this will help change the minds of India's
designers.
Fashion Guru Aki Narula, himself a Sikh, shaved off his beard and
threw away his turban six years ago.
But he now thinks he may have found a new look for his autumn
collection.
"I'm definitely going to use some of them," he told the BBC.
"I think they need little bit of grooming in terms of lessening the
whole macho image, being less aggressive more down to earth, you know
more easy with their bodies.
"I think they are ready to rock actually."
Glamour life
After 100 hours of training that includes advice on camera facing
techniques, deportment and even etiquette they are let loose in a
Delhi nightclub.
The organisers say most of them have never experienced this kind of
atmosphere before.
And to the few Westerners left watching, 18 young Sikh men taking to
the dance-floor in unison is indeed a curious sight.
But for these aspiring models it's a chance to taste the kind of life
they soon hope to be leading.
A life of parties and glamour that has until now largely been denied.
They are ready to conquer the world of fashion - but it's still not
clear whether it is ready for them.
