The TOWIE babe broke into a sweat while raising her heart rate during a gruelling exercise session.

Hitting the park with her personal trainer, the Essex babe was put through her paces lifting weights, jogging on the spot, and doing squats.

Wearing grey leggings and a teeny black sports bra, Lucy showed off her trim physique during the high action afternoon.

Despite sweating out her toxins, the fitness guru found room for a little glamour, injecting a splash of colour with pink nails.

The reality star has been focusing on her entrepreneurial skills, building her Results With Lucy business.

Speaking about her body shape as a teen, Mario Falcone's ex-fiancée said that she grew up being a beanpole.

She revealed: "Growing up in Brentwood I was always tall and skinny, and I kept that body shape through into my twenties.

"But as I got older I started to notice Cellulite developing on my bum and upper legs, and what I realised was that although I was still slim somehow I was carrying excess fat."

Lucy credits her trainer Cecilia with teaching her how to eat healthily and tone her body into being a strong lean machine rather than a size zero red carpet shadow.

She added: "Cecilia has taught me that healthy eating, coupled with regular exercising is the ONLY way to have the body that I want.

"Toned, strong and flexible, but without looking like a female weight lifter.

"One of the other great things about working out regularly is that you need to give more thought to what you eat.

"You can’t have the body of your dreams if you’re feeding it junk… I still have and love my cheat days, but the best thing is, they’re now guilt-free as I know that I’m on top of it!"
