Glow sticks at the ready! Lose weight and tone up with fitness craze that is all the rave

Slap on your shiny leggings and smear on some neon paint for the latest fitness trend

Club yourself fit at a rave exercise class

FLUORESCENT tubes and sweaty faces glow in the dark as the music pumps out of the speakers.

Welcome to the latest craze in fitness - having a good old rave.

Alcopops are swapped for water but leggings, neon, sweatbands and glow-sticks are positively encouraged in the classes by Fitness-Freak.com, which helps people sign up for fitness classes more easily.

The classes mean you can tone your body and burn calories while clubbing

"Fitness should be fun so we've made it that way," says founder Sandra Tochia.

"At the Fitness Freak RAVE, you don't even know you're working out."

Two pop-up classes are being held on September 17 and 18 in Camden, London.

A DJ spins old skool classics throughout the workout

This is an intense choreographed aerobic session to a live DJ spinning "old skool" 1990s dance classics.

The class starts with a pumping routine to get the heart rate up, followed by a mix of cardio,conditioning, toning and stretching.

"Prepare to burn some serious calories and expect to sweat," adds Sandra.

Ready, steady… glow!
