Abs factor: Fleur revealed her toned tummy as she performed on on the first live show  

The 26-year-old from East London told Women's Health that there are no quick fixes - it's all down to exercising regularly and eating well.

She said: 'I normally hit the gym five times a week. I tend to do half an hour of cardio – on the treadmill or a spin class – then head for the weights. I do a lot of core work, obviously!'

Appreciation: The judges were impressed with Fleur's performance as well as her figure

Beginners should start by trying to hold the position for 30 seconds. It involves lying face down on the floor, positioning your arms under your shoulders, and then lifting your body up so you're balanced on your toes and forearms. The stomach should be held it and beginners may be feel wobbly - it's certainly a move that's harder than it looks.

Variations include doing the plank side on, balancing on one forearm and the outside of the foot. 

Personal trainer and author of the Fat Burn Revolution Julia Buckley told MailOnline that Fleur is wise to do the plank for a toned tummy.

She said: 'The plank is one of the best exercises for tightening the tummy because it works the whole midsection of your body, including the deep abdominal muscles. It is also great for improving posture and balance and will build core strength to help you perform better many other exercises.'

Now Fleur is strong enough to hold the position for two minutes, Julia recommends she takes it further by adding some movement.
