Holly Willoughby makes rare outing in her gym gear

She's famed for her faultless sense of style, frequently leaving fans in awe of her chic ensembles.

But Holly Willoughby made a rare outing in her gym gear as she made her way into the ITV studios in a very relaxed outfit ahead of her stint on This Morning on Wednesday.

The 37-year-old TV presenter showed off her slim physique in black leggings and a coordinating black T-shirt as she made a high-spirited arrival at the venue. 

Holly's choice of top even flashed a glimpse of her bright pink sports bra thanks to its netted, mesh inserts above and beneath the bust.   

She toughened up the look with a black leather jacket and over-sized shades, while simple black running trainers completed her workout style. 

While Holly has remained tight-lipped on her fitness plan, insiders told New! magazine earlier this year that the mother-of-three is a fan of kickboxing, 

They claimed the Celebrity Juice star has been throwing herself into the intense sport to stay in shape - with each workout shedding a whopping 500-600 calories every hour.

The TV host has managed to fashion herself into something of a style icon thanks to her daily outfit posts which exhibit her polished style and weight loss - which is also said to be the result of mostly vegetables in her diet.   

A source said: 'Holly loves kickboxing and finds it an easy way to stay trim. She even has a kickboxing bag in her spare room, so she can work out at home.
