She admitted earlier this year that she is desperate to get into the best shape possible ahead of the summer.
But it seems Imogen Thomas might be pushing herself too far, judging by the 29-year-old star's message to followers on her Twitter page today.
The Welsh model was seen looking exhausted as she left a Bikram yoga studio in London, and admitted the workout had definitely taken its toll on her.
Pushing herself to the limit: Imogen Thomas admitted she was 'knackered' after a 2.5 hour workout today
She wrote on Twitter: 'WOW! I'm knackered. I've worked out for 2.5 hrs! Done the gym then a hardcore bikram session! #shaking.'
Imogen was seen heading home after the yoga class wearing a pair of tight black leggings and a cropped bra top with a black vest top tied at the waist over the top.
She had a towel slung over her gym bag and gulped water from a huge bottle after the difficult class – which sees attendees pushed even further in a yoga class completed in 105F heat.

Whoops! Imogen once again revealed too much as she bent over in her sheer leggings
However, despite her apparent exhaustion, Imogen still managed to primp and pose for the waiting photographers outside the studio.
After getting shots of her looking red-faced and puffed-out following the class, the snappers were treated to a shot of the former Big Brother contestant bending over.
And, given that her leggings were more than a little sheer, Imogen ended up revealing a bit too much as she bent down to pick up a bottle of water from the ground.
As well as working herself hard at yoga classes, Imogen has also been using weight loss aid SlimSticks to help shed the pounds.
Imogen has even been named the face of the drink sachets, which are intended help users eat 30 per cent less calories a day.
She said on the company's website: 'Slimsticks has been easy to incorporate into my daily routine and
since taking them my clothes are much looser on me.
'I've also noticed
that I haven’t stopped eating the foods I like, I'm just eating a bit
less of them.
'Hopefully, if I continue taking them I can lose that bit
of extra weight without loosing my curves.'
