Want a body like Denise's? Ms Richards revealed the secret behind her slim frame as she was spotted working out while wearing a pair of Zaggora Viva HotPants in Los Angeles earlier this week
She's got a figure that most women would die for.
And now Denise Richards has revealed the secret behind her slim figure - specialist weight loss trousers.
The 41-year-old actress was photographed wearing a pair of Zaggora Viva HotPants - believed to also be favoured by stars including Tess Daly - as she went for a run in Los Angeles earlier this week.
Limbering up: Denise teamed the trousers with a cropped white bra top to show off her enviable figure
Denise teamed the blue and orange half-length trousers with a cropped white bra-top to show off her washboard stomach and muscular physique.
The mother-of-three finished her outfit off by wearing her long blonde hair tied in a loose side ponytail, and clutched a bottle of water to ensure she stayed hydrated throughout her workout.
Just as with the original HotPants and the rest of the Zaggora range, the summer bright Viva HotPants range target the thighs, stomach and bottom, and claim they can help wearers lose two jean sizes in two weeks.

The shorts work by increasing perspiration - and the manufacturers say the results have been 'lab-proven' by scientists, after researchers from the Chelsea School of Sport at Brighton University found weight loss to be four times greater in subjects who exercised wearing the HotPants.
The core temperature in HotPants increased by an average of 18 per cent compared to the control, they found - with the effects ongoing after activity has ceased.
And Dessi Bell, Founder of Zaggora and the brain behind the product's advanced technology, said: 'We wanted to develop new products that our customers really wanted. Nothing is more powerful than putting customers in the driving seat.
'So, that is exactly what we have done and we are so proud of the results. Happy calorie burning!'
