Success: Together, the pair, who share six children together, have lost a combined 29.3 kilograms (65 lbs) - simply by working out regularly and eating clean

Out with the old: According to the pair, if you create new healthy habits, it's all about keeping them

'People who start the program are always saying "what happens if I gain all the weight back after eight weeks" and what we say to everybody is just to be present,' Sharny said.

'It's about creating new habits and then keeping with them for life.' 

Sharny, who started at 69 kilograms, lost an incredible 12.3 kilos (27 lbs) and now sits at 56.7 kilos. 

Amazing: Julius managed to lose an incredible 17 kilograms (37 lbs), dropping from 109.5 kilos (left) to 92.5 kilos (right)

Proud: 'It's amazing because for me it was about feeling good as a mum. Magnus is almost nine months old and I've been breastfeeding the whole time,' Sharny said

Healthy: 'I've cheated a couple of times but most of the time it's just been about hanging with the kids, being healthy, being happy and being present with them,' Julius said

Vanity: He also added that while initially he only wanted to lose 10 kilos, after that, anything was 'vanity'

'It's amazing because for me it was about feeling good as a mum. Magnus is almost nine months old and I've been breastfeeding the whole time,' she said. 

'He's healthy and chubby and happy and I'm thin and amazing. So I know that he was totally fine the entire time.' 

Julius managed to lose an incredible 17 kilograms (37 lbs), dropping from 109.5 kilos to 92.5 kilos.

'I've cheated a couple of times but most of the time it's just been about hanging with the kids, being healthy, being happy and being present with them,' he said.

Success: 'He's healthy and nice and chubby and happy and I'm thin and amazing. So I know that he was totally fine the entire time,' she said

Doting mum: 'As you get leaner people will say to you "oh you're not losing anymore weight are you?" and people have been saying that to me,' Sharny said

'And getting fitter so that I can be a better dad.

'Initially I said I just wanted to lose 10 kilos and anything after that was just vanity.' 

Sharny said she hopes to get as fit as possible.

'As you get leaner people will say to you "oh you're not losing anymore weight are you?" and people have been saying that to me,' she said.

'It's easy to get fat. So I want to go and get as lean as I can to see what my abs look like and what I can achieve and so does Julius because if I want to gain a kilo all I've got to do is have a piece of cake.'

At the beginning of the program, the pair explained that their reason for gaining the weight was to be as transparent and honest with their followers as possible. 

'A long time ago when we came out of our other industries and started in the fitness industry we both said that we would never talk s**t to anyone and always provide transparency,' Julius said in a live video on Facebook.

Transparent: 'We have seen fake people teaching people how to look a certain way even though they aren't doing it that way,' Julius said in August

'So Sharn and I have gotten nice and fat for ourselves.' 

The couple revealed that they had relaxed their strict diet and exercise plan and eaten whatever they wanted so they could do their programs all over again.

'We want to actually do it again and to do that we have to get fat. We now know that we have gotten into that dangerous place of eating because we're not just eating to get fat we've actually really enjoyed it,' Julius said.

'We are eating so much that it has become addictive. Today has been our last bender and it's been fun but it's got to stop because we are not here forever.' 

'We have noticed a difference in our kids while we have been junky junkies and we have become lazy and sort of brain dead.'

In it together: 'We want to actually do it again and to do that we have to get fat,' Julius said

Early days: Sharny (pictured left before starting her fitness program and right after her fit pregnancies) is an advocate for clean eating and quick and easy workouts 

Determined: Sharny has shared snaps of her working out while breastfeeding in the past 

Speaking to Daily Mail Australia in August about gaining weight, Sharny said she and her husband had been eating as much as they could.

'When it comes to food, we're not connoisseurs, we're gluttons. We had no plan to get fat, all it took was just to let the food take us where it wanted and eat whatever we felt like,' she said.

'Initially it was sickly, but it very quickly became fun, then addiction. We really wanted to go back into the FitMum and FitDad programs as realistically as possible for people.

'We're both now heavily addicted to sugar and junk food. Today is our first day on the program again, and we've both been thinking about junk food all day.'

Honest: Speaking to Daily Mail Australia about gaining weight, Sharny said she and her husband had been eating as much as they could

Big difference: Ms Kieser put the success of her fifth and sixth pregnancies down to what she calls a 'fit pregnancy,' where women stay active throughout their pregnancies

Making a change: ‘After the previous four pregnancies I was overweight and I had this "enough is enough" moment,' Ms Kieser told Daily Mail Australia in 2015

All about the kids: 'We do this for our kids, and going away to the gym loses that impact for them, because they just don't get to see how much fun fitness can really be,' Julius said

The program is eight weeks and is designed for parents with little time to exercise - each workout lasting just 15 minutes or less and able to be done with no equipment.

'They are meant to be done with kids around so they get to witness mum and dad having fun while getting fit,' she said. 

'We do this for our kids, and going away to the gym loses that impact for them, because they just don't get to see how much fun fitness can really be. This is the first time we've done it LIVE with our followers. 

Proud parents: 'They [the exercises] are meant to be done with kids around so they get to witness mum and dad having fun while getting fit,' Sharny said

Ms Kieser put the success of her fifth and sixth pregnancies down to what she calls a 'fit pregnancy,' where women stay active throughout their pregnancies. 

‘After the previous four pregnancies I was overweight and I had this "enough is enough" moment,' Ms Kieser told Daily Mail Australia in July, 2015.

'I looked at myself in the mirror and was like "oh my God who has eaten Sharny" - I felt like this fat old woman and that’s how I saw myself… it was all in my head but I just felt miserable.'

Fresh start: 'We are eating so much that it has become addictive. Today has been our last bender and it's been fun but it's got to stop because we are not here forever,' Julius said
