These super fit mums are superwomen - juggling motherhood with their quest for body beautiful.

They're yummy mummy's raising the bar, taking it to the extreme and losing their baby weight by entering bodybuilding competitions.

It will be Suzi Farrell's first time.

“Whenever I think of myself I think of the bigger girl until I do look in the mirror and it's just like wow if I can do it anybody can do it,"Suzi said.

From just two years ago - plus 60-kilos of post baby bulge - her transformation's nothing short of inspirational.

“I've gone from a size 22 to currently a size 8,"Suzi said.

She says now when she looks in the mirror she sees herself as “strong and confident”.

Sara Lochert, 36, has dropped five dress sizes thanks to pumping iron and her three kids.

“It just makes you a better mother if you try to put yourself not first but equal," Sarah said.

But it's not for the faint hearted. These women spend up to three hours a day in the gym and watch everything they eat - that is between cooking, cleaning, working, washing, and school pick-ups.

“You have to get up early in the morning before the kids get up, cardio three times a day and a weights session as well. I have to pick up my kids, help them with their homework and I have to do the housework, make their beds, get them ready for school, put them to bed on time - a workout in itself," Stephanie Ferretti said.

Today Tonight met mum-of-three Stephanie three years ago. Since then she's won two figure titles and now she's got the bodybuilding bug.

“I liked the euphoria i got from it, the release I got with the frustrations from being a single mum. Bodybuilding in general is an extreme sport - it's not for everyone," Stephanie said.

Suzi and Sara are now personal trainers and want to inspire other mums. Here are their top tips: eat protein with every meal and try to eat every 2-3 hours.

“That way your metabolism just keeps on burning all day," Stephanie said.

“I say to my clients, who are mothers, you just have to treat yourself like you would your child. You wouldn't send them off to kindy or school without food and yet a busy mother will walk off to work, shopping, whatever and she takes nothing and then she puts herself in the position that she's so hungry that she'll just eat whatever's in front of her," Sara said.

Carbs are a no-no after 4pm and don't just rely on cardio.

“Until you actually pick up a weight and do some resistance training you just cannot change those legs, you might lose weight but you're not going to get toned," Sara said.

In a few weeks they'll be showing off their sculpted, post-baby bodies, posing in a bikini on stage.

“I feel strong, I feel like I can stand with great posture and be a great role model to my kids and my clients," Sara said.

Top tips to get started

• Keep a food and exercise diary. This helps us be accountable for the food we have eaten, see where/when we are going wrong. eg. Eating late at night, the dodgy 3pm snack or simply make us stop & think before we grab that 3rd Tim tam, because we have to write it down.

• Cut down sugar intake

• Eat breakfast to get that metabolism started from the start of the day

• Get a calorie & fat counter booklet. This will help you make better choices eating at home or dining out & is a good eye opener, to where you may be going wrong available at news agencies for approx $7-$9. Contains calorie and fat content of all fast food and anything you would purchase in the supermarket.

• Set small achievable goals. Goals help give us focus and achieving them helps maintain the motivation to continue.

• Get out of your comfort zone for results. Increase intensity of work outs as you get fitter & stronger & learn to love sweat.

• Take measurements instead of just going by the scales. Your body composition can change overnight and sometimes we don’t see the hard work paying off on the scales but we have lost centimetres.

• Learn how to read nutrition labels on food & drink packaging, including the serving size.

• Avoid cutting out certain food groups, our bodies need them all to function at its best. Everything in moderation

• Get moving! Take any & every opportunity to increase physical activity, whether it be that spot of gardening, housework or walking the kids to school instead of driving. Every bit does help.
